Description

Technical Field

[0001] The present invention relates to the technical field related to satellite power supplies, and in particular to a power supply system bus architecture, an energy scheduling control method and a system. Background Art

[0002] In payload satellites such as synthetic aperture radar and laser, the power supply system is required to have the ability to output short-term, pulsed, and high power. Figure 1 The single, unregulated bus power architecture shown in the figure has a bus directly connected to a battery pack, and the on-orbit bus voltage fluctuates with the battery voltage. When pulse loads are operating, their power is provided by the power controller (Package Control Unit, PCU) and direct discharge from low-resistance batteries. Because the bus does not require closed-loop voltage regulation, this solution offers advantages such as fast response, simple structure, compact size and weight, and low cost. However, pulse loads can cause significant electromagnetic interference to the bus, impacting the normal operation of stable loads (single units with high bus stability requirements). Traditionally, a single battery pack configuration can result in a loss of power to the entire satellite payload and platform in the event of a battery pack failure, creating a single point of failure that can impact the satellite's lifespan and lead to poor stability and low reliability of the entire power system. Summary of the Invention

If either module fails, energy can be shared between the two buses through the other, improving system reliability and stability, increasing the power system's output power, and enhancing energy efficiency. The energy scheduling control module collects the voltages of the fully regulated platform busbar, the unregulated platform busbar, and the load busbar, and separately adjusts the operating states of the solar array power regulation module, the platform battery charge-discharge regulation module, and the energy conversion module to maintain the voltage of the fully regulated platform busbar within a preset stable range. The energy scheduling control module controls the intermittent operation of the power modules in rotation, simplifying converter design and extending the life of the power system. The power system busbar architecture of the embodiment of the present invention can solve the problems of poor stability and low reliability of the existing power system.

[0014] According to some embodiments of the present invention, the energy conversion module includes:

[0015] A load bus converter is connected between the platform fully adjustable bus and the load bus, and is used to convert the voltage output by the platform fully adjustable bus into a voltage and transmit it to the load bus;

[0016] The platform bus converter is connected in parallel with the load bus converter, and is used to convert the voltage output by the load bus into voltage and transmit it to the platform full-regulation bus.

[0019] The platform battery discharge electronic regulation module is used to receive the voltage output by the platform battery module, perform voltage conversion, and then transmit it to the platform full-regulation bus.

[0020] An energy scheduling control method according to an embodiment of the second aspect of the present invention is applied to the energy scheduling control module as described in the embodiment of the first aspect above, wherein the energy scheduling control module includes an energy scheduling inner loop and a load bus voltage stabilization inner loop; the energy scheduling control method includes the following steps:

[0027] According to some embodiments of the present invention, executing the energy scheduling strategy according to the total output power, the required power, the platform discharge operating condition, the discharge adjustment operating condition, and the load discharge operating condition includes the following steps:

[0028] If the total output power is lower than the required power, and the platform discharge condition indicates that the platform battery module is in a faulty condition, or the discharge regulation condition indicates that the platform battery charge and discharge regulation module is in a faulty condition, and the load discharge condition indicates that the load battery module is in a normal condition, the first scheduling strategy is executed.

[0035] According to some embodiments of the present invention, executing the third scheduling strategy according to the total output power, the required power, the platform charging power, and the load charging power includes the following steps:

[0036] If the total output power is greater than the sum of the required power and the platform charging power, and less than the sum of the required power, the platform charging power, and the load charging power, the third scheduling strategy is executed.

[0037] An energy dispatching and control system according to an embodiment of a third aspect of the present invention is applied to the energy dispatching and control module as described in the embodiment of the first aspect above, wherein the energy dispatching and control module includes an energy dispatching inner loop and a load bus voltage stabilization inner loop; the energy dispatching and control system includes:

[0038] a system state acquisition unit, configured to acquire the required power of the stable load, the total output power output by the solar cell array, the platform discharge operating condition of the platform battery module, the discharge regulation operating condition of the platform battery charge and discharge regulation module, and the load discharge operating condition of the load battery module;

[0039] An energy scheduling strategy execution unit is configured to execute an energy scheduling strategy based on the total output power, the required power, the platform discharge operating condition, the discharge regulation operating condition, and the load discharge operating condition, the energy scheduling strategy including a first scheduling strategy and a second scheduling strategy; wherein the first scheduling strategy includes the following steps: controlling the energy conversion module to schedule energy from the load bus and transmit it to the platform fully regulated bus, so that the platform fully regulated bus supplies power to the stable load, and the platform fully regulated bus sequentially supplies power to the low-power pulse load through the platform battery charge and discharge regulation module and the platform unregulated bus; and adjusting the operating states of the energy conversion module and the platform battery charge and discharge regulation module so that the voltage of the platform fully regulated bus remains within a preset fully regulated stable range; and the second scheduling strategy includes the following steps: disconnecting the energy scheduling inner loop from the energy conversion module, and selecting the load bus voltage stabilization inner loop to control the energy conversion module to schedule energy from the platform fully regulated bus and transmit it to the load bus, so that the voltage of the load bus remains within a preset load stable range and supplies power to the high-power pulse load.

[0040] The energy scheduling and control system according to the embodiment of the present invention has at least the following beneficial effects:

[0041] The system status acquisition unit can obtain the total output power of the solar cell array, the power demand of the stable load, the platform discharge condition of the platform battery module, the discharge regulation condition of the platform battery charge and discharge regulation module, and the load discharge condition of the load battery module. When the total output power of the solar cell array is lower than the demand power, the platform battery charge and discharge regulation module is required to discharge the platform battery module to the platform fully regulated bus, thereby providing operating voltage for the stable load. If the platform battery module or the platform battery charge and discharge regulation module fails, the load battery module will continue to operate normally. By controlling the energy conversion module to dispatch energy from the load bus and transfer it to the platform fully regulated bus, the voltage of the platform fully regulated bus can be stabilized, thereby supplying power to the stable load. Power can also be supplied to low-power pulse loads through the platform fully regulated bus, sequentially through the platform battery charge and discharge regulation module, and the platform unregulated bus. During this process, the operating states of the energy conversion module and the platform battery charge and discharge regulation module are adjusted to keep the voltage of the platform fully regulated bus within a preset stable range, thereby maintaining the normal operation of the power system. If the load battery module fails, the platform battery module and the platform battery charge-discharge regulation module continue to operate normally. By disconnecting the energy dispatch inner loop from the energy conversion module and selecting the load bus voltage stabilization inner loop to control the energy conversion module to dispatch energy from the platform fully regulated bus and transmit it to the load bus, the load bus voltage can be maintained at a normal level, ensuring the normal operation of high-power pulse loads. The energy dispatch control system of this embodiment of the present invention can ensure the normal operation of the power supply system by sharing energy between the platform fully regulated bus and the load bus when a platform battery module or platform battery charge-discharge regulation module fails, or when a load battery module fails. This improves system reliability and stability, increases the output power of the power supply system, and improves energy utilization efficiency.

[0063] The following will be combined Figures 1 to 3 A clear and complete description is given of the busbar architecture of the power supply system of the embodiment of the first aspect of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0064] The power system bus architecture according to the first embodiment of the present invention includes a bus architecture, a solar array power regulation module 500, a platform battery charge and discharge regulation module, a platform battery module 710 and a load battery module 720, an energy conversion module and an energy scheduling control module 900.

[0065] The busbar structure includes a platform fully regulated busbar 110, a platform unregulated busbar 120, and a load busbar 130. One end of the platform fully regulated busbar 110 is used to connect to the solar cell array 200, and the other end is used to connect to the stable load 300. One end of the platform unregulated busbar 120 is connected to the platform fully regulated busbar 110, and the other end is used to connect to the low-power pulse load 410. One end of the load busbar 130 is connected to the platform fully regulated busbar 110, and the other end is used to connect to the high-power pulse load 420.

[0066] The solar array power regulating module 500 is used to receive the total output voltage of the solar cell array 200 and supply power to the stable load 300 through the platform full regulation bus 110;

[0067] The platform battery charge and discharge regulation module has a charging input terminal, a discharging output terminal, and a platform unregulated bus 120 connection terminal. The charging input terminal and the discharging output terminal are both connected to the platform fully regulated bus 110. The platform unregulated bus 120 connection terminal is used to connect to the platform unregulated bus 120.

[0068] The platform battery module 710 and the load battery module 720 have one end connected to the platform unregulated bus 120 connection end and the platform unregulated bus 120, respectively, and the other end connected to the ground. The platform battery module 710 is used to store energy and supply power to the low-power pulse load 410 through the platform unregulated bus 120. The load battery module 720 has one end connected to the platform fully regulated bus 110 and the load bus 130, respectively, and the other end connected to the ground. The load battery module 720 is used to store energy and supply power to the high-power pulse load 420 through the load bus 130.

[0069] An energy conversion module is connected between the platform full-adjustment bus 110 and the load bus 130 and is used to control the direction of energy flow between the platform full-adjustment bus 110 and the load bus 130;

[0070] The energy scheduling control module 900 is used to collect the voltage of the platform's fully regulated bus 110, the voltage of the platform's unregulated bus 120, and the voltage of the load bus 130, and to adjust the operating states of the solar array power regulation module 500, the platform's battery charge and discharge regulation module, and the energy conversion module, respectively, so that the voltage of the platform's fully regulated bus 110 remains within a preset fully regulated stable range.

[0071] like Figure 3 As shown, solar cell array 200 outputs energy during the sunlit period and does not operate during the Earth's shadow period. During the sunlit period, the solar cell array 200 prioritizes energy output as follows: first, the solar array power conditioning module 500 supplies power to the stable load 300; second, the platform battery charge and discharge conditioning module charges the platform battery module 710; and third, the energy conversion module charges the load battery module 720. Excess energy is either short-circuited or consumed in an open circuit.

[0072] The solar array power regulation module 500 can adopt an S3R topology based on direct energy transmission or a DCDC converter based on Maximum Power Point Tracking (MPPT). Figure 3 As shown, the solar array power regulation module 500, the platform battery charge and discharge regulation module and the energy conversion module can all be connected in parallel to expand the conversion power. The specific number can be selected according to actual needs and should not be regarded as a limitation of the present invention.

[0073] The energy dispatch control module 900 utilizes a fully regulated bus error amplifier. By collecting the voltages of the platform's fully regulated bus 110, the platform's unregulated bus 120, and the load bus 130, it generates an energy dispatch signal through internal PID calculations. This signal controls the operating modes of the solar array power regulation module 500, the platform's battery charge-discharge regulation module, and the energy conversion module, achieving energy dispatch and ensuring that the voltage of the platform's fully regulated bus 110 remains within a preset fully regulated stability range under both steady-state and dynamic conditions. In some embodiments, the fully regulated bus error amplifier can employ triple or quad redundancy to improve reliability, but this is not intended to be a limitation of the present invention. The solar array power regulation module 500, the platform's battery charge-discharge regulation module, and the energy conversion module are all voltage-controlled constant current sources, meaning their output current amplitude is linearly proportional to the energy dispatch signal.

[0074] In some embodiments, the voltage of the platform fully regulated bus 110 is 42V, the voltage of the platform unregulated bus 120 is 26V to 38V, and the voltage of the load bus 130 is 80V to 120V, but the specific voltage values ​​cannot be regarded as limitations of the present invention.

[0075] The solar array power regulation module 500 is responsible for regulating the power of the solar cell array 200 during the sunshine period, and the platform battery charge and discharge regulation module is responsible for regulating the charge of the platform battery module 710 during the sunshine period and the discharge of the platform battery module 710 during the earth shadow period. The two modules work intermittently to generate the platform fully regulated bus 110 and the platform unregulated bus 120. First, the energy conversion module isolates the platform fully regulated bus 110 and converts it into charging for the load battery module 720, and generates the load bus 130. Figure 2As shown, the energy scheduling control module 900 internally includes an energy scheduling inner loop and a load bus voltage stabilization inner loop, and the energy conversion module has two corresponding operating modes. Under normal operating conditions, the output of the energy conversion module is connected to the load battery module 720, and the load battery access signal is in the on state. Under the control of the energy scheduling inner loop, the energy conversion module charges the load battery module 720 in a constant current and constant voltage mode according to a preset sequence. In the event of an open circuit fault in the load battery module 720, the load battery access signal is disconnected, and the energy conversion module outputs a stable voltage under the control of the load bus voltage stabilization inner loop, continuously supplying power to the high-power pulse load 420. Secondly, the energy conversion module isolates and transforms the load bus 130 to generate the platform fully regulated bus 110. Only when the platform battery module 710 fails due to open circuit or the platform battery charge and discharge regulation module fails, resulting in insufficient output power during the earth shadow period, the energy conversion module dispatches energy from the load bus 130 and transmits it to the platform fully regulated bus 110, so that the platform fully regulated bus 110 supplies power to the stable load 300, and the platform fully regulated bus 110 supplies power to the low-power pulse load 410 in turn through the platform battery charge and discharge regulation module and the platform unregulated bus 120.

[0076] The power system busbar architecture of the embodiment of the present invention adopts dual battery energy storage of the platform battery module 710 and the load battery module 720. When a single battery fails, energy can be released through the other group of batteries, and energy sharing between the platform full-regulation busbar 110 and the load busbar 130 is achieved through the energy conversion module, thereby improving system reliability. At the same time, compared with the traditional single-battery structure, the dual-battery structure improves the output power of the power system and has a high energy utilization rate.

[0077] In some embodiments, the energy conversion module and the load battery module 720 can be expanded as a whole, the input ends of the whole are connected to the platform full-regulation bus 110, and each of the wholes generates a load bus 130, thereby supplying power to multiple groups of high-power pulse loads 420.

[0078] According to the power system bus architecture of an embodiment of the present invention, a three-bus architecture consisting of a platform fully regulated bus 110, a platform unregulated bus 120, and a load bus 130 isolates the stable load 300, the low-power pulse load 410, and the high-power pulse load 420, thereby reducing electromagnetic interference from the stable load 300 when the low-power pulse load 410 and the high-power pulse load 420 are operating. The platform battery module 710 and the load battery module 720 form a dual-battery structure. The platform battery charge and discharge regulation module and the energy conversion module enable bidirectional energy flow between the platform fully regulated bus 110 and the load bus 130. If either the platform battery module 710 or the load battery module 720 fails, energy can be shared between the platform fully regulated bus 110 and the load bus 130 through the other, thereby improving system reliability and stability, increasing the output power of the power system, and improving energy utilization efficiency. The energy scheduling control module 900 can collect the voltage of the platform's fully regulated bus 110, the voltage of the platform's unregulated bus 120, and the voltage of the load bus 130, and separately adjust the operating states of the solar array power regulation module 500, the platform's battery charge and discharge regulation module, and the energy conversion module to maintain the voltage of the platform's fully regulated bus 110 within a preset stable range. The energy scheduling control module 900 controls the various power modules to operate intermittently in turn, reducing the design difficulty of the converter and extending the service life of the power system. The power system bus architecture of the embodiment of the present invention can solve the problems of poor stability and low reliability of existing power systems.

[0079] In some embodiments of the present invention, reference Figure 3 The energy conversion module includes a load bus converter 810 and a platform bus converter 820. The load bus converter 810 is connected between the platform fully regulated bus 110 and the load bus 130. The load bus converter 810 is used to convert the voltage output by the platform fully regulated bus 110 and transmit it to the load bus 130. The platform bus converter 820 is connected in parallel with the load bus converter 810. The platform bus converter 820 is used to convert the voltage output by the load bus 130 and transmit it to the platform fully regulated bus 110.

[0080] Under normal operating conditions, the load bus converter 810 isolates and converts the platform's fully regulated bus 110 to charge the load battery module 720, generating the load bus 130. Under the control of the energy scheduling inner loop, the load bus converter 810 charges the load battery module 720 in a constant current and constant voltage mode according to a preset sequence. In the event of an open-circuit fault in the load battery module 720, the load bus converter 810, under the control of the load bus voltage stabilization inner loop, outputs a stable voltage, continuously supplying power to the high-power pulse load 420.

[0081] Under normal operating conditions, the platform bus converter 820 does not operate. Only when the platform battery module 710 fails due to an open circuit or the platform battery charge and discharge regulation module fails, resulting in insufficient output power during the earth shadow period, does the platform bus converter 820 dispatch energy from the load bus 130 and transfer it to the platform fully regulated bus 110, allowing the platform fully regulated bus 110 to supply power to the stable load 300 and, in turn, to the low-power pulse load 410 via the platform battery charge and discharge regulation module and the platform unregulated bus 120.

[0082] Both load bus converter 810 and platform bus converter 820 can employ isolated topologies such as push-pull, full-bridge, and LLC, and can be connected in parallel to achieve power expansion. However, the specific structure and number of parallel converters are selected based on practical needs and should not be considered limitations of the present invention.

The specific working principles of the platform battery charge sub-regulation module 610 and the platform battery discharge sub-regulation module 620 are prior arts known to those skilled in the art and are not described in detail here.

[0084] The following will be combined Figures 1 to 4 The energy scheduling control method of the embodiment of the second aspect of the present invention is described clearly and completely. Obviously, the embodiment described below is only a part of the embodiments of the present invention, not all of the embodiments.

[0085] The energy scheduling control method according to the second embodiment of the present invention is applied to the energy scheduling control module 900 of the first embodiment. The energy scheduling control module 900 includes an energy scheduling inner loop and a load bus voltage stabilization inner loop. The energy scheduling control method includes the following steps:

[0086] Obtaining the power demand of the stable load 300, the total output power output by the solar cell array 200, the platform discharge condition of the platform battery module 710, the discharge regulation condition of the platform battery charge and discharge regulation module, and the load discharge condition of the load battery module 720;

[0087] Executing an energy scheduling strategy based on the total output power, the required power, the platform discharge condition, the discharge adjustment condition, and the load discharge condition, wherein the energy scheduling strategy includes a first scheduling strategy and a second scheduling strategy;

[0088] The first scheduling strategy includes the following steps: controlling the energy conversion module to dispatch energy from the load bus 130 and transmit it to the platform fully regulated bus 110, so that the platform fully regulated bus 110 supplies power to the stable load 300, and the platform fully regulated bus 110 supplies power to the low-power pulse load 410 through the platform battery charge and discharge regulation module and the platform unregulated bus 120 in sequence; adjusting the working states of the energy conversion module and the platform battery charge and discharge regulation module so that the voltage of the platform fully regulated bus 110 remains within a preset fully regulated stable range;

[0089] The second scheduling strategy includes the following steps: disconnecting the energy scheduling inner loop from the energy conversion module, and selecting the load bus voltage stabilization inner loop to control the energy conversion module to schedule energy from the platform full-regulation bus 110 and transmit it to the load bus 130, so that the voltage of the load bus 130 remains within the preset load stability range and supplies power to the high-power pulse load 420.

[0090] like Figure 3 As shown, the solar array 200 outputs energy during the sunlit period and does not operate during the Earth's shadow period. During the sunlit period, the solar array 200 prioritizes energy output as follows: first, the solar array power conditioning module 500 powers the stable load 300; second, the platform battery charge and discharge conditioning module charges the platform battery module 710; and finally, the energy conversion module charges the load battery module 720. Excess energy is short-circuited or consumed in an open circuit. During the Earth's shadow period, when the platform discharge, discharge conditioning, and load discharge conditions are all normal, the platform battery charge and discharge conditioning module regulates the discharge of the platform battery module 710, generating the platform fully regulated bus 110 to power the stable load 300. Under the control of the energy scheduling inner loop, the energy conversion module charges the load battery module 720 in a constant current and constant voltage mode according to a preset sequence, and generates the load bus 130 to power the high-power pulse load 420.

[0091] When the platform discharge condition or discharge regulation condition is a fault condition and the load discharge condition is a normal condition, energy is dispatched from the load bus 130 through the energy conversion module and transmitted to the platform full-regulation bus 110, so that the platform full-regulation bus 110 supplies power to the stable load 300, and the platform full-regulation bus 110 supplies power to the low-power pulse load 410 in turn through the platform battery charge and discharge regulation module and the platform unregulated bus 120.

[0092] When the platform discharge condition and the discharge regulation condition are both normal conditions and the load discharge condition is a fault condition, the energy conversion module outputs a stable voltage under the control of the load bus voltage stabilization inner loop, and always supplies power to the high-power pulse load 420.

[0093] It should be noted that if Figure 2 As shown, the energy scheduling control module 900 includes an operating mode selector. The energy scheduling control method of the embodiment of the present invention is implemented through the operating mode selector. The operating mode selector has a first input terminal, a second input terminal, a selection control terminal, and a selection output terminal. The first input terminal is connected to the energy scheduling inner loop, the second input terminal is connected to the load bus voltage stabilization inner loop, the selection output terminal is connected to the load bus converter 810, and the selection control terminal is used to input a load battery access signal. The load battery access signal is used to represent the load discharge condition of the load battery module 720, that is, the access status of the load battery module 720.

[0094] The energy scheduling control method of the embodiment of the present invention can release energy through another group of batteries when a single battery fails, and realize energy sharing between the platform full-regulation bus 110 and the load bus 130 through the energy conversion module, thereby improving system reliability. At the same time, compared with the traditional single-battery structure, the dual-battery structure improves the output power of the power supply system and has a high energy utilization rate.

[0095] According to the energy scheduling control method of an embodiment of the present invention, when the total output power of the solar cell array 200 is lower than the power demand of the stable load 300, the platform battery charge and discharge regulation module is used to discharge the platform battery module 710 to the platform fully regulated bus 110, thereby providing an operating voltage for the stable load 300. If the platform battery module 710 or the platform battery charge and discharge regulation module fails, the load battery module 720 continues to operate normally. By controlling the energy conversion module to dispatch energy from the load bus 130 and transmit it to the platform fully regulated bus 110, the voltage of the platform fully regulated bus 110 can be stabilized, thereby supplying power to the stable load 300. Power can also be supplied to the low-power pulse load 410 through the platform fully regulated bus 110, the platform battery charge and discharge regulation module, and the platform unregulated bus 120. During this process, the operating states of the energy conversion module and the platform battery charge and discharge regulation module are adjusted to maintain the voltage of the platform fully regulated bus 110 within a preset stable range, thereby maintaining the normal operation of the power system. If the load battery module 720 fails, the platform battery module 710 and the platform battery charge and discharge regulation module continue to operate normally. By disconnecting the energy scheduling inner loop from the energy conversion module and selecting the load bus voltage stabilization inner loop to control the energy conversion module to dispatch energy from the platform fully regulated bus 110 and transmit it to the load bus 130, the normal voltage of the load bus 130 can be maintained, ensuring the normal operation of the high-power pulse load 420. The energy scheduling control method of the embodiment of the present invention can ensure the normal operation of the power supply system by sharing energy between the platform fully regulated bus 110 and the load bus 130 when the platform battery module 710 or the platform battery charge and discharge regulation module, or the load battery module 720, thereby improving system reliability and stability, increasing the output power of the power supply system, and improving energy utilization efficiency.

[0096] In some embodiments of the present invention, reference Figure 3 , the energy scheduling strategy is executed according to the total output power, required power, platform discharge condition, discharge adjustment condition and load discharge condition, including the following steps:

[0097] If the total output power is lower than the required power, and the platform discharge condition indicates that the platform battery module 710 is in a fault condition, or the discharge regulation condition indicates that the platform battery charge and discharge regulation module is in a fault condition, and the load discharge condition indicates that the load battery module 720 is in a normal condition, the first scheduling strategy is executed.

[0098] During the Earth's shadow, the solar array 200 is inactive, and the total output power is lower than the required power. The platform battery charge and discharge regulation module regulates the discharge of the platform battery module 710, generating a platform fully regulated bus 110 to power the stable load 300. Under the control of the energy scheduling inner loop, the energy conversion module charges the load battery module 720 in a constant current and constant voltage mode according to a preset sequence, and generates a load bus 130 to power the high-power pulse load 420. When the platform discharge condition or the discharge regulation condition is a fault condition and the load discharge condition is a normal condition, the platform fully regulated bus 110 loses its power source. At this time, energy is dispatched from the load bus 130 through the energy conversion module and transmitted to the platform fully regulated bus 110, so that the platform fully regulated bus 110 supplies power to the stable load 300, and the platform fully regulated bus 110 supplies power to the small power pulse load 410 in turn through the platform battery charge and discharge regulation module and the platform unregulated bus 120. Energy sharing between the platform fully regulated bus 110 and the load bus 130 is achieved through the energy conversion module, thereby ensuring the normal operation of the power supply system when a fault occurs in the platform battery charge and discharge regulation module or the platform battery module 710, thereby improving system reliability and stability, increasing the output power of the power supply system, and improving energy utilization efficiency.

[0099] In some embodiments of the present invention, reference Figure 2 and Figure 3 Executing an energy scheduling strategy based on total output power, demand power, platform discharge conditions, discharge regulation conditions, and load discharge conditions also includes the following steps: If the load discharge condition indicates that the load battery module 720 is in a faulty operating condition, executing a second scheduling strategy. If both the platform discharge condition and the discharge regulation condition are normal, and the load discharge condition is a faulty operating condition, the energy conversion module outputs a stable voltage under the control of the load bus voltage stabilization inner loop, consistently supplying power to the high-power pulse load 420 and no longer being controlled by the energy scheduling inner loop. Regardless of whether the solar cell array 200 outputs sufficient energy, the energy conversion module consistently outputs voltage to the load bus 130 to ensure that the high-power pulse load 420 can still function normally even under the faulty load battery module 720.

[0100] In some embodiments of the present invention, reference Figure 3 , the energy scheduling strategy also includes a third scheduling strategy, and the energy scheduling control method further includes the following steps:

[0101] Obtaining the platform charging power required for charging the platform battery module 710 and the load charging power required for charging the load battery module 720;

[0102] If the total output power is greater than the sum of the required power and the platform charging power, but less than the sum of the required power, the platform charging power, and the load charging power, the third scheduling strategy is implemented;

[0103] Among them, the third scheduling strategy includes the following steps: controlling the solar array power regulation module 500 to output voltage to the platform full-regulation bus 110, so that the platform full-regulation bus 110 sequentially supplies power to the stable load 300, charges the platform battery module 710 through the platform battery charge and discharge regulation module, and charges the load battery module 720 through the energy conversion module; adjusting the input current of the energy conversion module so that the voltage of the platform full-regulation bus 110 is maintained within a preset full-regulation stable range.

[0104] The energy output of the solar cell array 200 exceeds the combined energy requirements of the stable load 300 and the platform battery module 710. The surplus energy cannot meet the energy requirements of the load battery module 720. At this point, the solar array power conditioning module 500 outputs all of the energy from the solar cell array 200 to the platform fully regulated bus 110, powering the stable load 300 and charging the platform battery module 710. The surplus energy is then passed through the load bus converter 810 to charge the load battery module 720. Under the control of the energy scheduling control module 900, the load bus converter 810 stabilizes the platform fully regulated bus 110 voltage at 42V by regulating its input current. The input current of the load bus converter 810 is proportional to the amplitude of the energy scheduling signal. The platform bus converter 820 and the platform battery discharge sub-regulation module 620 are inoperative.

[0105] In some embodiments of the present invention, the energy scheduling strategy also includes a fourth scheduling strategy, a fifth scheduling strategy, and a sixth scheduling strategy. If the total output power is greater than the sum of the required power, the platform charging power, and the load charging power, the fourth scheduling strategy is executed: the solar array power conditioning module 500 is controlled to output voltage to the platform fully regulated bus 110, and the energy transmitted from the solar cell array 200 to the platform fully regulated bus 110 is reduced by shunting to the ground or disconnecting the path. At this time, the platform bus converter 820 and the platform battery discharge sub-regulation module 620 are inoperative; the platform battery charge sub-regulation module 610 draws power from the platform fully regulated bus 110 to charge the platform battery module 710 and power the low-power pulse load 410, while the load bus converter 810 draws power from the platform fully regulated bus 110 to charge the load battery module 720 and power the high-power pulse load 420.

[0106] If the total output power is greater than the required power, but the surplus energy cannot meet the platform charging power required to charge the platform battery module 710, the fifth scheduling strategy is implemented: the solar array power regulation module 500 is controlled to output all power to the platform fully regulated bus 110 to power the stable load 300. Surplus energy is used to charge the platform battery module 710 through the platform battery charging sub-regulation module 610. Under the control of the energy scheduling control module 900, the platform battery charging sub-regulation module 610 stabilizes the platform fully regulated bus 110 voltage at 42V by adjusting the input current of the platform battery charging sub-regulation module 610. The input current of the platform battery charging sub-regulation module 610 is proportional to the amplitude of the energy scheduling signal. The load bus converter 810, the platform bus converter 820, and the platform battery discharge sub-regulation module 620 do not operate.

[0107] If the total output power is less than the required power, the sixth scheduling strategy is executed: the solar array power regulation module 500 is controlled to output all power to the platform full-regulation bus 110, and the platform battery module 710 is controlled to discharge. The platform battery discharge sub-regulation module 620 replenishes energy for the platform full-regulation bus 110 and stabilizes the voltage of the platform full-regulation bus 110 at 42V. The output current of the platform battery discharge sub-regulation module 620 is inversely proportional to the amplitude of the energy scheduling signal. The platform battery charge sub-regulation module 610, the load bus converter 810, and the platform bus converter 820 do not operate.

[0108] The following will be combined Figures 1 to 4 The energy dispatching and control system of the embodiment of the third aspect of the present invention is described clearly and completely. Obviously, the embodiment described below is only a part of the embodiments of the present invention, not all of the embodiments.

[0109] According to the energy scheduling and control system of the third aspect embodiment of the present invention, the energy scheduling and control module 900 of the above-mentioned first aspect embodiment is applied, and the energy scheduling and control module 900 includes an energy scheduling inner loop and a load bus voltage stabilization inner loop; the energy scheduling and control system includes a system state acquisition unit and an energy scheduling strategy execution unit.

[0110] A system status acquisition unit, configured to acquire the power demand of the stable load 300, the total output power of the solar cell array 200, the platform discharge condition of the platform battery module 710, the discharge regulation condition of the platform battery charge and discharge regulation module, and the load discharge condition of the load battery module 720;

[0111] An energy scheduling strategy execution unit is configured to execute an energy scheduling strategy based on the total output power, the required power, the platform discharge operating condition, the discharge regulation operating condition, and the load discharge operating condition, wherein the energy scheduling strategy includes a first scheduling strategy and a second scheduling strategy. The first scheduling strategy includes the following steps: controlling the energy conversion module to schedule energy from the load bus 130 and transmit it to the platform fully regulated bus 110, so that the platform fully regulated bus 110 supplies power to the stable load 300, and the platform fully regulated bus 110 supplies power to the low-power pulse load 410 via the platform battery charge and discharge regulation module and the platform unregulated bus 120 in sequence; and adjusting the operating states of the energy conversion module and the platform battery charge and discharge regulation module so that the voltage of the platform fully regulated bus 110 remains within a preset fully regulated stable range. The second scheduling strategy includes the following steps: disconnecting the energy scheduling inner loop from the energy conversion module, and selecting the load bus voltage stabilization inner loop to control the energy conversion module to schedule energy from the platform fully regulated bus 110 and transmit it to the load bus 130, so that the voltage of the load bus 130 remains within a preset load stable range and supplies power to the high-power pulse load 420.

[0112] like Figure 3 As shown, the solar array 200 outputs energy during the sunlit period and does not operate during the Earth's shadow period. During the sunlit period, the solar array 200 prioritizes energy output as follows: first, the solar array power conditioning module 500 powers the stable load 300; second, the platform battery charge and discharge conditioning module charges the platform battery module 710; and finally, the energy conversion module charges the load battery module 720. Excess energy is short-circuited or consumed in an open circuit. During the Earth's shadow period, when the platform discharge, discharge conditioning, and load discharge conditions are all normal, the platform battery charge and discharge conditioning module regulates the discharge of the platform battery module 710, generating the platform fully regulated bus 110 to power the stable load 300. Under the control of the energy scheduling inner loop, the energy conversion module charges the load battery module 720 in a constant current and constant voltage mode according to a preset sequence, and generates the load bus 130 to power the high-power pulse load 420.

[0113] When the platform discharge condition or discharge regulation condition is a fault condition and the load discharge condition is a normal condition, energy is dispatched from the load bus 130 through the energy conversion module and transmitted to the platform full-regulation bus 110, so that the platform full-regulation bus 110 supplies power to the stable load 300, and the platform full-regulation bus 110 supplies power to the low-power pulse load 410 in turn through the platform battery charge and discharge regulation module and the platform unregulated bus 120.

[0114] When the platform discharge condition and the discharge regulation condition are both normal conditions and the load discharge condition is a fault condition, the energy conversion module outputs a stable voltage under the control of the load bus voltage stabilization inner loop, and always supplies power to the high-power pulse load 420.

[0115] It should be noted that if Figure 2 As shown, the energy scheduling control module 900 includes an operating mode selector. The energy scheduling control system of the embodiment of the present invention is implemented by the operating mode selector. The operating mode selector has a first input terminal, a second input terminal, a selection control terminal, and a selection output terminal. The first input terminal is connected to the energy scheduling inner loop, the second input terminal is connected to the load bus voltage stabilization inner loop, the selection output terminal is connected to the load bus converter 810, and the selection control terminal is used to input a load battery access signal. The load battery access signal is used to indicate the load discharge condition of the load battery module 720, that is, the access status of the load battery module 720.

[0116] The energy dispatching and control system of the embodiment of the present invention can release energy through another group of batteries when a single battery fails, and realize energy sharing between the platform full-regulation bus 110 and the load bus 130 through the energy conversion module, thereby improving system reliability. At the same time, compared with the traditional single-battery structure, the dual-battery structure improves the output power of the power supply system and has a high energy utilization rate.

[0117] According to an embodiment of the energy dispatch and control system of the present invention, the system status acquisition unit can obtain the total output power of the solar array 200, the power demand of the stable load 300, the platform discharge condition of the platform battery module 710, the discharge regulation condition of the platform battery charge and discharge regulation module, and the load discharge condition of the load battery module 720. When the total output power of the solar array 200 is lower than the demand power, the platform battery charge and discharge regulation module is required to discharge the platform battery module 710 to the platform fully regulated bus 110, thereby providing an operating voltage for the stable load 300. If the platform battery module 710 or the platform battery charge and discharge regulation module fails, the load battery module 720 will continue to operate normally. By controlling the energy conversion module to dispatch electrical energy from the load bus 130 and transmit it to the platform fully regulated bus 110, the voltage of the platform fully regulated bus 110 can be stabilized, thereby supplying power to the stable load 300. Furthermore, power can be supplied to the low-power pulse load 410 via the platform fully regulated bus 110, the platform battery charge and discharge regulation module, and the platform unregulated bus 120. During this process, the operating states of the energy conversion module and the platform battery charge and discharge regulation module are adjusted to maintain the voltage of the platform fully regulated bus 110 within a preset stable range, thereby maintaining the normal operation of the power system. If the load battery module 720 fails, the platform battery module 710 and the platform battery charge and discharge regulation module continue to operate normally. By disconnecting the energy scheduling inner loop from the energy conversion module and selecting the load bus voltage stabilization inner loop, the energy conversion module is controlled to dispatch energy from the platform fully regulated bus 110 and transmit it to the load bus 130. This ensures the normal voltage of the load bus 130 and ensures the normal operation of the high-power pulse load 420. The energy scheduling and control system of this embodiment of the present invention can ensure the normal operation of the power system by sharing energy between the platform fully regulated bus 110 and the load bus 130 when the platform battery module 710 or the platform battery charge and discharge regulation module, or the load battery module 720, thereby improving system reliability and stability, increasing the output power of the power system, and improving energy utilization efficiency.
