Description

Technical Field

[0002] The energy storage inverter system integrates an inverter, a photovoltaic controller, and a battery charge and discharge controller, and can provide two power supply modes for the load: inverter and mains. The inverter power supply energy can come from the energy storage battery and the photovoltaic system. When the photovoltaic energy is sufficient, the system will give priority to using photovoltaic energy to power the load and charge the energy storage battery. When the photovoltaic energy is insufficient, the system will switch to using the energy storage battery to provide energy. However, even in the absence of load, the inverter itself has static losses, resulting in power loss of the energy storage battery.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a structural schematic diagram of an embodiment of the energy storage inverter system provided by the present invention. Figure 2 It is a flow chart of an embodiment of the intelligent adjustment method for standby power consumption provided by the present invention. Figure 3It is a module schematic diagram of the battery charging and discharging unit and the inverter unit provided by the present invention. The energy storage inverter system includes a photovoltaic panel 11, an MPPT (Maximum Power Point Tracking) unit 12, an energy storage battery 13, a battery charging and discharging unit 14 and an inverter 15. The photovoltaic panel 11 is connected to the MPPT unit 12, the energy storage battery 13 is connected to the battery charging and discharging unit 14, and the battery charging and discharging unit 14 and the MPPT unit 12 are both connected to the inverter 15. The photovoltaic panel 11 is a device for directly converting sunlight into electrical energy. Through the photovoltaic effect, the photovoltaic panel 11 can convert solar energy into direct current electrical energy. The MPPT unit 12 is used for maximum power point tracking, that is, by adjusting the working point of the photovoltaic panel 11, its output power reaches the maximum value. The energy storage battery 13 is used to store the electrical energy generated by the photovoltaic panel 11. In this way, power can continue to be supplied at night or when there is insufficient light. The battery charging and discharging unit 14 is used to control the charging and discharging process of the energy storage battery 13 to ensure the safe operation of the energy storage battery 13 and extend the battery life. The inverter 15 is used to convert DC power into AC power so as to transmit the power to a power grid or provide the power to a load 16 for use.

[0038] The battery charging and discharging unit 14 includes a high-voltage power circuit 141, and a high-voltage drive circuit 142 connected to the high-voltage power circuit. The high-voltage power circuit 141 includes a high-voltage diode circuit (not shown), a low-voltage power circuit 143 and a low-voltage drive circuit 144 connected to each other. The inverter unit 15 includes an inverter power circuit 151 and an inverter drive circuit 152 connected to each other. The interconnection and cooperation of these components can realize the charge and discharge control of the energy storage battery and the DC to AC power conversion of the inverter. The high-voltage and low-voltage parts can handle the power of the voltage range of different energy storage batteries, thereby effectively managing the battery charge and discharge process.

[0039] The intelligent adjustment method for standby power consumption provided by the present invention comprises the following steps:

[0040] S101: Acquire the current working mode of the energy storage inverter system according to a preset period, and acquire the current photovoltaic voltage of the photovoltaic panel and / or the current load power of the inverter unit.

[0041] In a specific implementation scenario, a plurality of different working modes are preset for the energy storage inverter system, and the working modes include energy-saving modes and non-energy-saving modes, and the energy-saving modes include a plurality of different N-level energy-saving modes, N∈{1,2,3…}. In different energy-saving modes, the high-voltage drive circuit, the high-voltage diode circuit, the low-voltage drive circuit and the inverter drive circuit are turned on and off. It can be understood that the more drive circuits are turned off, the lower the power consumption of the energy storage inverter system. Specifically, in this embodiment, the working modes include: any one of non-energy-saving mode, the first energy-saving mode, the second energy-saving mode, and the third energy-saving mode. In different levels of energy-saving modes, the system flexibly adjusts the control strategy according to the load demand and the change of photovoltaic voltage to minimize unnecessary energy consumption. In this way, the energy efficiency and energy saving of the system can be improved while ensuring the power supply of important loads, and more efficient energy utilization can be achieved.

[0042] When the energy storage inverter system is in the first energy-saving mode, the high-voltage drive circuit is driven to turn off, the high-voltage diode circuit is turned on, the low-voltage power circuit and the low-voltage drive circuit are turned on, and the inverter power circuit and the inverter drive circuit are turned on. In the first energy-saving mode, even if the high-voltage drive circuit of the battery charging and discharging unit is turned off, the high-voltage diode circuit in the high-voltage power is in a conducting state, and the high-voltage discharge path of the energy storage battery is not completely closed. By starting the high-voltage diode circuit, the energy storage battery can still provide energy to the load through this path. This method can ensure that even in the first energy-saving mode, the energy storage inverter system can still flexibly adjust the energy output to adapt to load changes. Turning off the high-voltage drive circuit of the battery charging and discharging unit can reduce the power consumption on the high-voltage side of the energy storage inverter system, thereby reducing the standby power of the entire energy storage inverter system. This can reduce the energy consumption of the system when the load is low and improve the energy efficiency of the system.

[0043] When the energy storage inverter system is in the second energy-saving mode, the low-voltage drive circuit is further driven to work intermittently on the basis of the first energy-saving mode. By making the low-voltage side drive of the battery charge and discharge control unit work intermittently, the system can further reduce energy consumption. When the load power is low, reducing the operating frequency of the battery charge and discharge unit can effectively reduce the power consumption of the system, thereby achieving energy-saving effects.

[0044] When the energy storage inverter system is in the third energy-saving mode, the inverter drive circuit is further driven to shut down on the basis of the second energy-saving mode. By shutting down the inverter drive circuit of the inverter unit, the system can reduce power consumption to a minimum. In the case of low load power, shutting down the inverter drive circuit of the inverter unit can effectively reduce the energy consumption of the system and achieve more efficient energy-saving effects.

[0045] After the inverter drive circuit is turned off, the inverter drive circuit is started periodically to detect the load access status of the energy storage inverter system and obtain the load power of the access load, so that the mode can be switched in time according to the change of the load power.

[0046] In this embodiment, the current photovoltaic voltage of the photovoltaic panel and / or the current load power of the inverter unit are periodically obtained to ensure that the system can monitor the load changes in time so as to switch the mode in time when the load changes, so that the system can flexibly adjust the working state of each circuit according to the real-time load conditions. This intelligent control can help the system better balance the energy supply and load demand, thereby improving the energy efficiency and performance stability of the system. At the same time, it can more accurately match the power supply and load demand. This helps to avoid energy waste and unnecessary energy consumption. In this way, it can effectively save electricity, improve energy utilization efficiency, and quickly adjust the working state of each circuit according to real-time data to ensure that the mode can be switched in time when the load changes, provide sufficient power support, and ensure that the system operates at the highest efficiency at all times.

[0047] In one implementation scenario, voltage sensors are equipped, which can directly measure the voltage of the photovoltaic panels. Through these sensors, the energy storage inverter system can obtain real-time data on the photovoltaic voltage. The inverter unit is usually equipped with a current sensor to measure the current of the load. By measuring the product of current and voltage, the system can calculate the power of the load. Some inverter systems may also be directly equipped with power sensors to measure the power of the load. This sensor can directly provide real-time data on the load power. Some control algorithms are also used to monitor and manage the operating status of the system. These algorithms can calculate the photovoltaic voltage and load power based on parameters such as voltage and current.

[0048] In one implementation scenario, the energy storage inverter system uses a state machine to manage different operating modes. A state machine is a mathematical model that describes the transition rules between different states of the system. The system controller determines the current operating state based on input signals and internal logic. Alternatively, the energy storage inverter system is equipped with a control algorithm to determine the current operating mode based on sensor data and set parameters.

[0049] S102: Obtaining a target mode of the energy storage inverter system based on the working mode, photovoltaic voltage and / or load power.

[0050] In a specific implementation scenario, an energy-saving strategy is set for each different mode according to the energy-saving needs, and the judgment conditions corresponding to each energy-saving strategy are set, such as photovoltaic voltage threshold, load power threshold, etc. Based on the real-time collected data and the set conditions, a logical judgment is performed to determine whether the energy-saving mode should be switched. In this implementation scenario, combining multiple factors for judgment can reduce the risk of misjudgment. Relying on a single factor for judgment may increase the possibility of misjudgment, and comprehensive consideration of multiple factors can improve the accuracy of judgment. Comprehensive consideration of energy-saving mode, photovoltaic voltage and load power can help the system more accurately judge the current working status, avoid unnecessary energy-saving strategy adjustments, and improve the stability and energy-saving effect of the system.

[0051] When the working mode is non-energy-saving mode, if the photovoltaic voltage is less than the preset threshold voltage, and the load power is less than the preset first threshold power for a duration longer than the preset first duration, the target mode is the first energy-saving mode. When the photovoltaic voltage is lower than the preset threshold voltage and the load power is low, it may mean that the system is currently under a lighter workload. Switching to the first energy-saving mode can reduce the standby power of the system, save energy and extend the use time of the energy storage battery. This helps to reduce energy waste and improve the energy efficiency performance of the system. In addition, reducing the energy consumption of the system can reduce the operating pressure of the system and improve the stability and reliability of the system.

[0052] When the working mode is the first energy-saving mode, if the load power is less than the preset second threshold power, the target mode is the second energy-saving mode, and the second threshold power is lower than the first threshold power. When the load power is lower than the second threshold power, it proves that the load of the inverter system is lower at this moment, so it is necessary to switch to the second energy-saving mode, and intermittently start the low-voltage side drive on the basis of turning off the high-voltage side drive. This can reduce the standby power of the system, thereby reducing the energy consumption of the system. When the load is low, adjusting in this way can effectively reduce the static power consumption of the system. In addition, it can also reduce the operating pressure of the equipment, reduce the wear and loss of the equipment, and thus extend the service life of the equipment.

[0053] In some cases, the system may need to respond quickly to changes in load. By keeping the low-voltage side drive circuit intermittently started, the system can respond more quickly to changes in load demand, thereby maintaining system stability and performance, and also ensuring that the system remains operational, avoiding the energy consumption and time delay when the system is completely shut down and restarted. This helps maintain system continuity and stability.

[0054] When the working mode is the second energy-saving mode, if the load power is less than the preset third threshold power for a duration longer than the preset second duration, the target mode is the third energy-saving mode, and the third threshold power is lower than the second threshold power. When the load power is lower than the third threshold power, it means that there is almost no load at present, so the inverter drive circuit of the inverter can be turned off. Turning off the inverter drive circuit of the inverter can significantly reduce the energy consumption of the system. In the case of almost no load, maintaining the operation of the inverter drive circuit will consume a certain amount of energy, and turning off this part of the circuit can save energy. The standby power of the system can also be reduced. When the load is extremely low or almost no load, keeping the inverter drive circuit running will cause the static power consumption of the system to increase, and turning off this part of the circuit can effectively reduce the standby power. In addition, it can reduce the operating pressure of the equipment, reduce the wear and loss of the equipment, and help extend the service life of the equipment.

[0055] In one embodiment, in order to ensure that the system can smoothly and orderly return to normal working state when exiting the energy-saving mode, taking into account the stability, performance and energy-saving effect of the system, the energy-saving mode is exited step by step according to the steps of entering the energy-saving mode. That is, exit from the third energy-saving mode to the second energy-saving mode, then exit from the second energy-saving mode to the first energy-saving mode, and then exit from the first energy-saving mode to the non-energy-saving mode. Exiting step by step can ensure that the system is gradually adjusted when returning to the normal working mode, avoiding the sudden load change or system state change from affecting the system stability. Exiting the energy-saving mode step by step can help the system maintain stable operation. In the process of gradually increasing system load, exiting step by step can ensure that the system can adapt to the change of load and avoid the impact of sudden load increase on system stability. Exiting the energy-saving mode step by step can ensure that the system can still maintain a certain energy-saving effect when exiting the energy-saving mode. By exiting step by step, the system can gradually return to normal working state while maintaining energy saving, avoiding energy waste. In addition, exiting the energy-saving mode step by step according to the reverse path can ensure that the system can maintain good performance during the switching process between different working states. This method can better control the operating state of the system and improve the performance and efficiency of the system.

[0056] In one implementation scenario, when the working mode is the third energy-saving mode, the inverter drive circuit is periodically turned on for a short time to detect the load power. If the load power is lower than the preset first return power, the inverter drive circuit is turned off to maintain the third energy-saving mode. If the load power is greater than the preset first return power, the target mode is the second energy-saving mode. When the load power is greater than the preset first return power, it proves that the system has a certain load demand, so it is necessary to start the inverter drive circuit. The system will switch to the second energy-saving mode. The second energy-saving mode slightly increases power consumption than the third energy-saving mode to meet the load demand, but still maintains the basic principle of energy saving. The system can maintain a certain energy-saving effect while meeting the load demand.

[0057] In one implementation scenario, when the working mode is the second energy-saving mode, if the load power is greater than the preset second return power, the target mode is the first energy-saving mode, and the second return power is greater than the first return power. When the load power exceeds this second return power, the system will consider that the load demand has become more significant. The system will switch to the first energy-saving mode to provide sufficient energy to meet the higher load demand while maintaining the energy-saving principle as much as possible. By switching to the first energy-saving mode when the load power exceeds the second return power, the system can maintain a certain level of energy saving while ensuring that the load demand is met. The first energy-saving mode can provide more energy to ensure that the system operates stably under higher load conditions.

[0058] In one implementation scenario, when the working mode is the first energy-saving mode, if the load power is greater than the preset third return power, the target mode is the first energy-saving mode, and the third return power is greater than the second return power. When the load power exceeds the third return power, the system will consider that the load demand has become very significant. Staying in the first energy-saving mode can ensure that the system maintains stable operation under higher load conditions, and has sufficient energy supply to meet high load demands, avoiding system failure or performance degradation due to insufficient energy supply.

[0059] In one embodiment, when the working mode is any one of the first energy-saving mode, the second energy-saving mode and the third energy-saving mode, if the photovoltaic voltage is greater than the preset exit threshold, the target mode is the non-energy-saving mode. When the photovoltaic voltage is higher than the preset exit threshold, the system may indicate that the photovoltaic power generation system is generating too much electrical energy. Once the photovoltaic voltage exceeds this threshold, the system may need to take measures to avoid damage or overload. When the photovoltaic voltage is higher than the preset exit threshold, the system will switch to the non-energy-saving mode. The non-energy-saving mode is usually the normal operating mode of the system, and the system will provide enough energy to meet the load demand. This strategy helps protect the system from the risks that may be caused by excessive photovoltaic voltage and ensures that the system operates stably within a safe range.

[0060] It can be seen from the above description that in this embodiment, the energy-saving mode of the energy storage inverter system is intelligently adjusted according to the current working mode, photovoltaic voltage and load power. Different energy-saving measures are taken according to different energy-saving modes, and various circuits of the energy storage inverter system, such as high-voltage drive circuit, low-voltage drive circuit, inverter drive circuit, etc., are controlled to be turned off or turned on accordingly according to the target mode to reduce the standby power consumption of the energy storage inverter system, thereby effectively avoiding the waste of electricity.
