Description
Technical Field
[0001] The present invention relates to the field of power generation and energy storage technology, and specifically to an intelligent multi-source input new energy control system based on a 240V DC architecture. Background Art
[0002] In recent years, multi-source input power generation systems have attracted widespread attention due to their ability to integrate multiple renewable energy sources. Such systems usually combine solar energy, wind energy, and other forms of renewable energy to improve power generation efficiency and reliability. However, traditional multi-source input power generation systems still have some problems, such as low energy conversion efficiency, high system complexity, and high failure rate.
[0003] Traditional multi-source input power generation systems often require multiple power conversion units to adapt to different types of input energy, which usually involves multiple power conversion processes. For example, the output of solar cells needs to be regulated by a DC / DC converter, and wind power generation needs to be converted into AC power through a DC / AC inverter. This type of multi-stage conversion not only increases energy loss, but also makes system design more complicated and difficult to maintain.
[0004] In addition, existing systems usually lack intelligent management methods and cannot dynamically adjust energy distribution according to changes in environmental conditions and load demand. When encountering sudden loads or failures, the system may not be able to respond in time, causing equipment damage or downtime. In addition, data collection and status monitoring of traditional multi-source systems are mostly passive and lack real-time prediction functions, which in turn affects the life management of equipment, increases maintenance costs and system instability.
[0005] In order to solve the above problems, there is an urgent need for a new system that can improve the conversion efficiency of multi-source input power generation systems, reduce energy losses, and achieve intelligent dynamic management. The system should have high-efficiency power conversion technology and combine intelligent data analysis and status prediction to achieve adaptive energy allocation and extend equipment life.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0050] See also Figure 1-Figure 12 The present invention provides an intelligent multi-source input new energy control system based on a 240V DC architecture, including a power generation module, a 240V DC bus, an energy storage module, a load module and an energy intelligent management and control module, wherein the new energy power generation module includes hydropower generation and geothermal power generation.
[0051] The power generation module includes a photovoltaic power generation module, a wind power generation module, a fuel cell module, a mains power module and a diesel engine module; wherein the energy storage module is used to store electric energy when the power demand is less than the power generation, and output electric energy when the power demand is higher than the power generation; the load module is used to provide a load for the circuit to simulate the actual usage scenario, and change in real time according to the user's demand for electricity; the energy intelligent management and control module is used to monitor the system circuit and the environment, obtain power allocation control parameters, calculate and regulate the circuit through the system, obtain and make adaptive adjustments to the system circuit according to the actual system circuit situation and the environment.
[0052] The photovoltaic power generation module comprises a photovoltaic array and a first DC / DC conversion module. The photovoltaic array is connected to a 240V DC bus access unit after being rectified by the first DC / DC conversion module.
[0053] Furthermore, the first DC / DC conversion module has a built-in maximum power point tracking (MPPT) control unit to ensure that the photovoltaic power generation system can achieve maximum power output under different light intensities and ambient temperatures, thereby optimizing power generation efficiency.

[0056] The local energy storage unit includes impact-resistant energy storage devices such as compressed air energy storage devices and flywheel energy storage devices. When the power generation power of the wind turbine group is higher than the load power, part of the generated electricity is used to supply power to the 10kV AC bus, and the other part is used to charge the local energy storage unit. When the power supply power of the wind turbine group is lower than the load power, the local energy storage unit is used as a supplementary power source to supply power to the load at the same time.
[0057] The oil engine module includes a high-voltage 10kV oil engine or a low-voltage 0.4kV oil engine. The high-voltage oil engine is connected to a 10kV AC bus input unit, and the low-voltage oil engine is connected to a 0.4kV AC bus input unit.
[0058] The energy storage module includes energy storage battery group 1, energy storage battery group 2, ..., energy storage battery group n, and the energy storage module monitors and controls the energy storage state through a battery management system (BMS). The energy storage battery group adopts a high-efficiency lithium battery group, and realizes charge and discharge management through a bidirectional DC / DC module.
[0059] When the load demand is low or there is excess photovoltaic power generation, the energy storage module will store excess energy; when the load demand increases or power generation is insufficient, the energy will be supplemented through the 240V DC bus. The energy storage module also has rapid response capabilities and energy allocation functions, and is connected to the energy intelligent management and control module through a power electronic converter to ensure system load stability.
[0060] The load module includes existing AC and DC loads and newly added loads. Specifically, the load module includes 48V DC loads, 220V AC loads, and newly added 240V equipment loads.
[0061] The energy intelligent management and control module is the core management unit of the entire system. Further, the energy intelligent management and control module includes a data receiving submodule, an impact parameter prediction submodule, a data evaluation prediction module submodule, and a power control submodule.
[0062] Furthermore, the data receiving submodule is used to receive the environmental data set and the power data information;
[0063] The impact parameter prediction submodule is used to combine the environmental data set and the power data information to calculate the impact of various parameters in the environmental data set on the power data information and obtain the impact parameters;

[0069] A stability control unit is used to obtain stability control parameters according to the optimal energy allocation parameter set and the power data information set; and output the stable current parameters, optimal energy allocation parameters, protection control parameters and stability control parameters as an optimal power control scheme.
[0070] The energy intelligent management and control module enables the proposed system to have multiple operation modes to adapt to different load requirements and environmental conditions:
[0071] Independent power supply mode: When the mains is disconnected, the system uses photovoltaic, wind power and energy storage modules to independently supply power to the load, ensuring continuous operation even in an environment without mains. Grid-connected operation mode: When the mains is connected, the system automatically adjusts the power supply ratio of different power sources according to real-time load demand, and feeds excess power back to the grid through the grid-connected interface. This mode can input excess power into the grid when the photovoltaic and wind power generation is high, so as to achieve efficient use of energy.
[0072] Intelligent switching mode: When photovoltaic and wind power cannot meet the load demand, the system automatically switches to the energy storage module or fuel cell module to ensure the stable operation of critical loads. The switching process in this mode is controlled by the energy intelligent management and control module, which automatically judges the power input situation to perform seamless switching and avoid power interruption.
[0073] It is worth noting that in order to improve the reliability of this system, the energy storage module adopts a redundant design. The energy storage module is equipped with several battery modules. When one battery module fails, the system automatically switches to other battery modules to ensure continuous power supply of the system.
[0074] Furthermore, in order to improve the reliability of the operation of the energy storage module, it is necessary to prevent the normal operation of the energy storage module from being affected by interference from the external environment. Figure 1-Figure 12 As shown, the battery module includes a temperature-controlled battery compartment 1 and a battery (not shown) arranged in the temperature-controlled battery compartment 1, the temperature-controlled battery compartment 1 includes a rectangular frame 2 and a liquid-cooling plate component 3 fixedly assembled on both sides of the rectangular frame, an opening 21 is provided on one side of the rectangular frame 2, and a sealing plate 22 is detachably provided at the opening 21.
[0075] Multiple batteries connected in series can be placed in the temperature-controlled battery compartment 1. The temperature-controlled battery compartment 1 and the multiple batteries connected in series inside it can constitute a battery pack. During the battery charging and discharging process, the liquid cooling plate component 3 is tightly attached to both sides of the battery to cool the battery by heat transfer to prevent the battery temperature from being too high and affecting the normal operation of the energy storage module.
[0076] like Figure 5 and Figure 6 As shown, the liquid cooling plate component 3 includes a positioning plate 31 and a movable liquid cooling plate 32; Figure 7 As shown, the positioning plate 31 is evenly penetrated with strip-shaped through grooves 311 along its length direction, and the cross section of the strip-shaped through grooves 311 decreases from one side of the battery to the other side to form a cone-shaped structure, and the positioning plate 31 between adjacent strip-shaped through grooves 311 is evenly provided with supporting prisms 312 on the side close to the battery, and the first contact surface 313 contacting the battery is formed on the side of the supporting prisms 312 on the positioning plate 31 away from the positioning plate 31;
[0077] like Figure 5 and Figure 8As shown, the movable liquid cooling plate 32 includes a strip portion 321 adapted in the strip through groove 311 and a connecting portion 322 evenly arranged between adjacent strip portions 321, and a conical through hole 323 is formed between two adjacent strip portions 321 and two adjacent connecting portions 322. The movable liquid cooling plate 32 is located on the side of the positioning plate 31 close to the battery, and a flat second contact surface 324 is formed on the side of the movable liquid cooling plate 32 close to the battery;
[0078] like Figure 5 and Figure 6 As shown, the movable liquid cooling plate 32 can slide between the first position and the second position in a direction perpendicular to the positioning plate 31 under the drive of the driving component; when the movable liquid cooling plate 32 is in the first position, the outer wall of the strip portion 321 of the movable liquid cooling plate 32 is in contact with the inner wall of the strip through groove 311, the inner wall of the conical through hole 323 is in contact with the outer wall of the corresponding supporting prism 312, and the second contact surface 324 is located on the side of the first contact surface 313 away from the battery (i.e., Figure 5 As shown in FIG. 1 ), when the movable liquid cooling plate 32 is in the second position, the second contact surface 324 is flush with the first contact surface 313 (ie, as shown in FIG. 1 ). Figure 6 as shown).
[0079] The present invention can enable the temperature-controlled battery compartment 1 to dissipate heat and keep the battery warm according to different environments (ie, in summer and winter).
[0080] Specifically, in summer, due to the high ambient temperature, the external battery will generate heat during the charging and discharging process. In this stage, the movable liquid cooling plate 32 can be driven by the driving component (which can be an electric push rod) to move the movable liquid cooling plate 32 to the second position. At this time, the second contact surface 324 of the movable liquid cooling plate 32 is in close contact with the battery side wall to improve the cooling effect on the battery. In this process, the movable liquid cooling plate 32 and the positioning plate 31 are separated, and the outside air can contact the battery through the strip-shaped through groove 311 and the conical through hole 323, further improving the cooling effect on the battery (i.e., Figure 4 as shown).
[0081] In winter, due to the low ambient temperature, although the battery generates heat during the charging and discharging process, the battery does not generate heat when it is not working. In this stage, the movable liquid cooling plate 32 can be driven by the driving component (an electric push rod can be used) to move the movable liquid cooling plate 32 to the first position. At this time, the movable liquid cooling plate 32 is in contact with the positioning plate 31, and the strip portion 321 of the movable liquid cooling plate 32 can block the strip through groove 311 of the positioning plate 31. The supporting prism of the positioning plate 31 can block the conical through hole 323 of the movable liquid cooling plate 32, so that the temperature-controlled battery compartment 1 is in a closed state, and the first contact surface 313 of the movable liquid cooling plate 32 is separated from the battery (i.e., Figure 3 As shown), heat exchange between the air in the temperature-controlled battery compartment 1 and the outside air is avoided to achieve the purpose of keeping the battery warm.
[0082] like Figure 3 , Fig.10 and Fig.12 As shown, further, fixed columns 4 are fixed at the four corner positions of the positioning plate 31 away from the battery side, and a coolant inlet pipe 5 and a coolant outlet pipe 6 are respectively fixed between the two fixed columns 4 at both ends of the positioning plate 31, and the coolant inlet pipe 5 and the coolant outlet pipe 6 are respectively located at the strip-shaped through grooves 311 at both ends of the positioning plate 31, and the coolant inlet pipe 5 and the coolant outlet pipe 6 are connected to the movable liquid cooling plate 32 through a plurality of telescopic connecting pipes 8, and the movable liquid cooling plate and the coolant inlet pipe 5 and the coolant outlet pipe 6 are evenly provided with preload springs 7.
[0083] Based on the above design, in summer, the coolant circulation system supplies liquid to the coolant inlet pipe 5. After the coolant enters the coolant inlet pipe 5, under the pressure of the coolant, the telescopic connecting pipe 8 will extend so that the movable liquid cooling plate 32 moves to the second position and stretches the preload spring 7, automatically realizing the cooling treatment of the battery. In winter, the coolant circulation system stops working. At this time, under the elastic force of the preload spring 7, the movable liquid cooling plate automatically moves to the first position to achieve the sealing of the temperature-controlled battery compartment 1 and the heat preservation treatment of the battery.
[0084] Furthermore, air flow grooves (not shown) are evenly arranged on the second contact surface 324. External air can flow in the air flow grooves to improve the cooling efficiency of the battery.
[0085] Through experiments, it was found that the response time of the system during peak load demand periods is controlled at the millisecond level, which significantly improves the stability and reliability of the system. The system is predicted by monitoring environmental information and combining power parameters. The prediction results are used to determine the regulation of various new energy equipment in the next stage, so that the current power supply system is in a pre-action state to prevent a major impact caused by an adverse condition. At the same time, the reduction in the life of the equipment or device is predicted based on the changes in various parameters. In addition, the battery module of the energy storage module has high stability and avoids battery aging caused by environmental influences, thus extending the service life of the battery module.
[0086] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
