[0039] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, system, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, system, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, system, article or device including the elements.

[0041] like Figure 1 As shown, the present invention provides a park power allocation method, which includes steps S11-S13:

[0042] In step S11, the output power of the park clean power source and the total power of the park load are obtained in real time, wherein the park clean power source includes any one or more of wind power generation, photovoltaic power generation and hydropower generation;

[0043] In step S12, when the output power of the park clean power source is greater than the total power of the park load, the excess portion of the output power of the clean power source is stored in the park energy storage device;

[0044] In step S13, when the output power of the park clean power supply is less than the total power of the park load, the electric energy in the park energy storage device is used preferentially.

[0045] In one embodiment, the output power of the park's clean power supply and the total power of the park's load are first monitored in real time. The clean power supply may include any one or more combinations of wind power generation, photovoltaic power generation, and hydropower generation. When the output power of the clean power supply exceeds the total power of the park's load, the excess electric energy will be stored in the park's energy storage device to cope with the peak energy demand that may occur in the future. When the output power of the clean power supply is not enough to meet the total power of the park's load, the system will give priority to using the electric energy in the energy storage device, ensuring that the park can continue to operate without immediately relying on external energy when the clean energy supply is insufficient. When the total output power of the clean power supply, energy storage device, area grid power supply, and emergency power supply still cannot meet the total power of the park's load, the emergency power supply is used for power supply. If there is still a problem of insufficient power supply, the power supply of the low-priority power loop line is suspended step by step according to the priority of the power loop line in the park, giving priority to ensuring that the critical load can get power supply first. Through the industrial control switch with the Internet of Things function, the switch of any power loop line can be accurately controlled. The Internet of Things function allows remote monitoring and control, which improves the flexibility and response speed of the entire technical solution. Through real-time monitoring, energy storage, priority scheduling and IoT control, the park's energy use is optimized, energy efficiency is improved, and the stability and reliability of energy supply are ensured. In addition, it can reduce dependence on non-renewable energy to a certain extent, and bring certain economic benefits by incorporating clean energy into the power grid or other parks, promoting the park's transformation to a greener and more sustainable energy use model.

[0046] The technical solution in this embodiment can scientifically and reasonably allocate the output power of the park's clean power supply, while ensuring the safe and sufficient power supply of the park's power loads, and at the same time ensuring the maximum utilization rate of the park's clean power supply.

[0047] In one embodiment, Figure 2 As shown, the following steps S21-S22 are also included:

[0048] In step S21, the power output of the park clean power is allocated by the first-level power dispatching device;

[0049] In step S22, the park's power input is allocated through the second-level power dispatching device, and the park's power input includes any one or more of the park's clean power supply, the power supply in the park's energy storage device, the substation grid power supply and the emergency power supply, and the emergency power supply includes any one or more of the fuel cell power generation and fossil fuel power generation in the park.

[0050] In one embodiment, the main task of the first-level power dispatching device is to allocate the power output of the park's clean power. The dispatching device is responsible for controlling the output power of clean energy such as wind power generation, photovoltaic power generation and hydropower generation to meet the power demand of the park or perform corresponding power storage. The role of the second-level power dispatching device is to more widely allocate the power input of the park. It includes not only the clean power in the first level, but also the power in the park's energy storage device, the power grid power in the substation area and the emergency power supply.

[0051] The park has a variety of power input sources, which can be selected according to actual conditions. Clean power sources, such as wind, photovoltaic and hydroelectric power. Energy storage devices, which store excess clean power for use during peak demand or other power shortages. Substation grid power, connected to the wider grid, as a supplement to the power supply. Emergency power supply, which provides backup power, including fuel cell power generation and fossil fuel power generation. Emergency power supply is to ensure that the power supply of the park is not interrupted in an emergency. Use hydrogen or other fuels to generate electricity through chemical reactions, or use fossil fuels such as coal, oil or natural gas to burn and generate electricity.

[0052] The power dispatching device needs to decide the distribution of electric energy based on factors such as the actual power demand of the park, the availability, priority and efficiency of the power supply. Usually, clean power is preferred because it has less impact on the environment and has low electricity costs. When clean power is not enough to meet the demand, energy storage devices and substation grid power will be used as supplements. In an emergency, the emergency power supply will be enabled to ensure the power supply of critical loads. The design of the entire power dispatching system realizes the reliability, flexibility and sustainability of the park's power supply. The technical solution in this embodiment can optimize the cost of using electric energy, reduce the impact on the environment, and ensure a stable power supply in all situations.

[0053] In one embodiment, Figure 3 As shown, the following steps S31-S33 are also included:

[0054] In step S31, when the output power of the park clean power source is greater than the total power of the park load, and the storage capacity of the park energy storage device reaches a preset saturation power threshold, the excess output power of the clean power source is transmitted to the gain area, and the gain area includes the substation power grid and the park external power consumption area;

[0055] In step S32, when the combined output power of the park clean power source and the park energy storage device is less than the total power of the park load, the power grid power source of the substation is used for power supply;

[0056] In step S33, when the combined output power of the park clean power supply, the park energy storage device and the substation grid power supply is less than the total power of the park load, an emergency power supply is used for power supply.

[0057] In one embodiment, when there is a surplus of clean power, when the output power of the park's clean power (such as wind power, photovoltaic power, and hydropower) exceeds the total power of the park's load, and the power of the park's energy storage device has reached a preset saturation power threshold, the energy storage device will not be further charged, but the excess clean power will be delivered to the gain area. The gain area includes the substation power grid and the power consumption area outside the park. Part of the substation power grid can deliver electricity to a wider power grid for power supply or storage in other areas. Part of the power consumption area outside the park can deliver electricity to other power consumption areas outside the park, which may be used for commercial transactions or to support the power needs of neighboring parks or communities.

[0058] When the output power of the clean power source is not enough to meet the load of the park alone, but the storage capacity of the energy storage device has not reached the saturation threshold, the energy in the energy storage device will be used first. However, once the energy storage device reaches saturation, the system will no longer charge the energy storage device from the clean power source, but will transfer the excess energy to the gain area.

[0059] When the combined output power of the park's clean power supply and the park's energy storage device is less than the total power of the park's load, the system will use the area's grid power supply for supplementary power supply. When clean energy and energy storage resources are insufficient, the grid power supply will be used as a secondary power source to ensure that the park's power needs are met. If the total output power of the park's clean power supply, the park's energy storage device, and the area's grid power supply is still less than the total power of the park's load, the system will enable the emergency power supply to supply power. The emergency power supply is designed as a last resort to provide power in extreme situations to ensure the uninterrupted operation of critical facilities and loads.

[0060] The technical solution in this embodiment realizes a multi-level and multi-source energy supply system. Through intelligent management and optimized scheduling, it improves the flexibility and reliability of energy use in the park, helps reduce dependence on a single energy source, improves energy utilization efficiency, and enhances the park's ability to adapt to power supply fluctuations. At the same time, the excess clean power supply is transmitted to the gain area, which not only improves the economy of energy, but also helps reduce energy waste and promotes the sustainable use of energy.

[0061] In one embodiment, Figure 4 FIG. 1 is a block diagram of a park power allocation device according to an exemplary embodiment. Figure 4 As shown, the park power allocation device includes an acquisition module 41, a storage module 42 and a priority module 43.

[0062] The acquisition module 41 is used to acquire the output power of the park clean power source and the total power of the park load in real time, wherein the park clean power source includes any one or more of wind power generation, photovoltaic power generation and hydropower generation;

[0063] The storage module 42 is used to store the excess output power of the clean power source in the park energy storage device when the output power of the park clean power source is greater than the total power of the park load;

[0064] The priority module 43 is used to give priority to using the electric energy in the park energy storage device when the output power of the park clean power source is less than the total power of the park load.

[0065] The acquisition module 41, the storage module 42 and the priority module 43 included in the block diagram of the park power allocation device are controlled to execute the park power allocation method described in any of the above embodiments.

[0066] In one embodiment, Figure 5 The invention is a schematic diagram of a park power dispatching system according to an exemplary embodiment, and the park power dispatching system includes a first-level power dispatching subsystem and a second-level power dispatching subsystem. The park is divided into a source area, a gain area and a load area, and the partitioning is for better execution of the subsequent power dispatching method. The source area is the power collection area of ​​the entire solution, which includes the power grid power of the substation area, the first-level power dispatching power, the energy storage power, and the emergency power. The above multiple power are uniformly managed by the second-level power dispatching device. The power dispatching device is mainly composed of an energy router, which can integrate multiple different powers and different types of power. When the power from one source is unstable or short of power, it automatically switches to another power to ensure the stable supply of power. At the same time, power output interfaces of various specifications are provided for different types of electrical appliances to work. Emergency power is generally generated by emergency generators. The power in the gain area mainly comes from clean energy, including but not limited to non-polluting power such as photovoltaic power generation, wind power generation, and hydropower station power generation. The power generated by clean energy is first connected to the first-level power dispatching device. After the device collects power, there are three directions of power use, first supplying it to the second-level power dispatching device, then charging it to the energy storage device, and finally flowing to the power grid in the gain area. The load area is the power equipment area of ​​the entire park. Taking the factory park as an example, it is divided into three areas. Each project can increase, decrease or change the area classification according to needs. Each area has multiple circuit loops, and various equipment is mounted under the loops.

[0067] Furthermore, the first-level power dispatching subsystem is used to allocate the power output of the park clean power supply. When the output power of the park clean power supply is greater than the total power of the park load, the excess part of the output power of the clean power supply is stored in the park energy storage device; when the output power of the park clean power supply is greater than the total power of the park load, and the storage capacity of the park energy storage device reaches the preset saturation power threshold, the excess part of the output power of the clean power supply is delivered to the gain area, and the gain area includes the substation power grid and the park external power consumption area. The second-level power dispatching subsystem is used to allocate the park power input, and the park power input includes any one or more of the park clean power supply, the power supply in the park energy storage device, the substation power grid power supply and the emergency power supply, and the emergency power supply includes any one or more of the fuel cell power generation and the fossil fuel power generation in the park; when the combined output power of the park clean power supply and the park energy storage device is less than the total power of the park load, the substation power grid power supply is used for power supply; when the combined output power of the park clean power supply, the park energy storage device and the substation power grid power supply is less than the total power of the park load, the emergency power supply is used for power supply.
