[0025] FIG. 1 is a flowchart of a method for energy storage regulation according to an embodiment of the present application. The method can be performed by an energy storage regulation device or an electronic device, which can be implemented by software and / or hardware, and can be integrated into any smart device with network communication function. As shown in FIG. 1, the method for energy storage regulation can include the following steps:

[0026] S101, when the microgrid is disconnected from the main grid, calculating the power absorbed or output by the microgrid in the main grid at the current time.

[0027] In a power system, the microgrid and the main grid refer to two different scale and function power grid systems, and there is a certain interaction and dependence between them. The main grid refers to a large power network in a certain regional range, which is the core part of the power system, responsible for large-scale power transmission and distribution. The main grid is usually composed of high-voltage transmission lines, substations and multiple power plants, and can cover a larger geographical area and connect numerous users and distributed power sources. The main function of the main grid is to ensure the continuous and reliable supply of power, and can exchange and schedule power between different geographical locations. The microgrid is a smaller independent power grid system that can provide power services in a localized area. The design purpose of the microgrid is to improve the reliability, flexibility and efficiency of the power system, especially in remote areas or places with high power quality requirements.

[0028] FIG. 2 is a schematic diagram of a water-light-storage microgrid according to an embodiment of the present application. As shown in FIG. 2, the microgrid can include a water power device, a photovoltaic device, an energy storage device, and a load device. The water power device usually refers to a device that uses water power to generate electricity. In a microgrid environment, the water power device can be a small hydroelectric generator or a micro hydroelectric station. The photovoltaic device refers to a solar photovoltaic power generation system, including solar panels (photovoltaic panels), inverters and other components. These devices directly convert sunlight into electricity and are one of the important renewable power sources in the microgrid. The energy storage device is a device used to store electrical energy, and common energy storage devices include lithium battery packs, lead-acid batteries, super capacitors, etc. They can store excess electricity when the power generation is greater than the power consumption, and release it when needed, thereby balancing the supply and demand relationship and improving the stability of the microgrid. The load device refers to the terminal user equipment or system that consumes electricity, such as household appliances, industrial machinery, lighting systems, etc. In the microgrid, the load device is the power consumer, and its electricity demand determines the operation mode and energy scheduling strategy of the microgrid.

[0029] S102, if the absolute value of the power absorbed or output by the microgrid in the main grid at the current time is less than or equal to the maximum output power of the energy storage device in the microgrid, controlling the energy storage device to output energy to the microgrid at the current time.

[0030] In the specific embodiments of the present application, the power of the micro-grid absorbing energy from or outputting energy to the main grid at the current time can be represented as ΔP, and the maximum output power of the energy storage device in the micro-grid can be represented as P m In this step, when the absolute value of ΔP is less than or equal to P m , the power of the hydroelectric equipment in the micro-grid outputting energy to the micro-grid at the current time and the power of the photovoltaic equipment in the micro-grid outputting energy to the micro-grid at the next time and the power of the load equipment in the micro-grid absorbing energy from the micro-grid at the next time are obtained first, then the power of the energy storage device absorbing energy from or outputting energy to the micro-grid at the next time is calculated according to the power of the hydroelectric equipment outputting energy to the micro-grid at the next time, the power of the photovoltaic equipment outputting energy to the micro-grid at the next time and the power of the load equipment absorbing energy from the micro-grid at the next time, and then the energy storage device is controlled to output energy to the micro-grid at the next time according to the power. For example, the energy storage device can output energy to the micro-grid at the power of |P2-P1|, wherein P1 is the sum of the power of the hydroelectric equipment outputting energy and the power of the photovoltaic equipment outputting energy, and P2 is the power of the load equipment consuming energy.

[0031] S103, calculating the corresponding capacity storage ratio of the energy storage device at the next time of the current time.

[0032] The capacity storage ratio in the embodiments of the present application is the ratio of the energy stored by the energy storage device to its maximum capacity, represented as S, and the condition that S should satisfy is 10%≤S≤90%. Having energy redundancy in the energy storage device is beneficial to prolong the service life of the energy storage device, and is also beneficial to adjust the small changes.

[0033] S104, controlling the energy storage device to absorb energy from or output energy to the micro-grid at the next time according to the corresponding capacity storage ratio of the energy storage device at the next time.

[0034] The minimum capacity storage ratio in the embodiments of the present application is 10%, and the maximum capacity storage ratio is 90%. In this step, if the corresponding capacity storage ratio of the energy storage device at the next time is less than or equal to the minimum capacity storage ratio, the energy storage device is controlled to absorb energy from the micro-grid at the next time, and if the corresponding capacity storage ratio of the energy storage device at the next time is greater than or equal to the maximum capacity storage ratio, the energy storage device is controlled to output energy to the micro-grid at the next time. For example, the energy storage device can absorb energy from or output energy to the micro-grid at the power of |P2-P1|, wherein P1 is the sum of the power of the hydroelectric equipment outputting energy and the power of the photovoltaic equipment outputting energy, and P2 is the power of the load equipment consuming energy.

That is, in the technical solution of the present application, the energy storage device can be controlled to absorb or output energy in the micro-grid according to the corresponding capacity storage ratio of the energy storage device. In the related art, the energy storage device will change between the charging and discharging states quickly and continuously when the energy storage is used for frequency regulation, and such high-frequency change will reduce the service life of the device to some extent.

[0040] S304, if the corresponding capacity storage ratio of the energy storage device at the next time is less than or equal to the minimum capacity storage ratio, controlling the energy storage device to absorb energy in the micro-grid at the next time.

[0041] In this step, the power of the hydropower equipment in the microgrid outputting energy to the microgrid at the next time, the power of the photovoltaic equipment in the microgrid outputting energy to the microgrid at the next time, and the power of the load equipment in the microgrid absorbing energy in the microgrid at the next time can be acquired first; then the power of the energy storage device absorbing energy in the microgrid at the next time is calculated according to the power of the hydropower equipment outputting energy to the microgrid at the next time, the power of the photovoltaic equipment outputting energy to the microgrid at the next time, and the power of the load equipment absorbing energy in the microgrid at the next time; and then the energy storage device is controlled to absorb energy in the microgrid at the next time according to the power.

[0042] S305, if the corresponding capacity storage ratio of the energy storage device at the next time is greater than or equal to the maximum capacity storage ratio, the energy storage device is controlled to output energy to the microgrid at the next time.

That is, in the technical solution of the present application, the energy storage device can be controlled to absorb or output energy in the micro-grid according to the corresponding capacity storage ratio of the energy storage device. In the related art, when the energy storage is used for frequency regulation, the energy storage device will change between charging and discharging states quickly and continuously, and such high-frequency change will reduce the service life of the device to some extent.

[0046] S401, when the micro-grid is disconnected from the main grid, calculating the power of energy absorbed or output by the micro-grid in the main grid at the current time.

[0047] S402, if the absolute value of the power of energy absorbed or output by the micro-grid in the main grid at the current time is greater than the maximum output power of the energy storage device, cutting off one or more load devices in the micro-grid.

[0048] The cut-off load device in the embodiments of the present application refers to removing a device that is consuming power from the micro-grid to prevent overload or other electrical problems. Since the adjustment of the load device is adjusted in series and cannot be continuous, it is often impossible to accurately achieve P1 and P2 in actual situations, so when cutting off the load device, the following conditions should be met: P1≤P2; |P2-P1|≤P m .
