[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Power system flexibility refers to the ability of the power system to quickly adjust its operating status, maintain supply and demand balance, and ensure the stability and reliability of power supply when facing uncertain factors such as load changes, new energy access, and emergencies. Generally, it can adapt to random changes in power generation, power grids, and loads at a certain cost by optimizing and deploying various available resources.

[0045] As an important part of the modern power system, energy storage devices are valued for their rapid response and versatility. They can not only quickly adjust power output in a short period of time to achieve peak load shifting, but also provide backup capacity in emergency situations to ensure the safety and stability of the power system. In response to the volatility and intermittency brought about by the access of new energy systems, energy storage devices can store excess electrical energy and release electrical energy when energy supply is insufficient, quickly respond to the dispatching instructions of the power grid, and ensure the stable operation of the power grid.

[0046] Based on this, the present invention proposes a method for regulating energy storage power, which improves the flexibility of the power system by effectively regulating the power of the energy storage device. Figure 1 , Figure 1 The following is a flow chart of a method for regulating energy storage power according to an embodiment of the present invention. The method includes:

[0047] Step 120: Use the new energy units within the preset range of the target energy storage device as the target new energy unit group corresponding to the target energy storage device.

[0048] There are multiple energy storage devices in the power system. The number of energy storage devices in the power system is not fixed. It depends on many factors such as the scale of the power grid, the proportion of new energy access, and power demand. These energy storage devices play an important role in the regulation of new energy systems and power grids.

[0049] In an embodiment of the present invention, the power regulation method of each energy storage device in the power system can be optimized. Each energy storage device in the power system can support the access and regulation of multiple new energy units. Therefore, it is necessary to divide the new energy units, divide each new energy unit into a corresponding energy storage device, and determine the new energy unit that each energy storage device is responsible for.

[0050] Specifically, the adjustment range of each energy storage device is determined, and the new energy units within the adjustment range of each energy storage device are included in the new energy machine group of the corresponding energy storage device, so that the energy storage device can adjust the power according to the power change of the corresponding new energy machine group. In one embodiment of the present invention, the target energy storage device is any energy storage device among all the energy storage devices in the power system, and the target new energy machine group corresponding to the target energy storage device within the range is determined by specifying the adjustment range of the target energy storage device.

[0051] Step 140: Obtain the power change rate of the target new energy machine group and the capacity of the target energy storage device.

[0052] There will be power fluctuations in daily power grid operation. If the power fluctuations are large, it will affect the normal operation of the power grid, especially when the load fluctuates or the external environment of renewable energy changes, the power fluctuations will be more obvious. Therefore, the power change rate of the target renewable energy group can be obtained to adjust the power of the target energy storage device based on the power change rate of the target renewable energy group to balance the power fluctuations of renewable energy.

[0053] In the embodiment of the present invention, it is also necessary to obtain the capacity of the target energy storage device. The capacity of the energy storage device represents the ability of the energy storage device to store energy and limits the regulation ability of the energy storage device.

[0054] Step 160: construct a power regulation model of the target energy storage device based on the capacity of the target energy storage device.

[0055] Since the inherent conditions of the target energy storage device will limit the power regulation capability of the target energy storage device, a power regulation model of the target energy storage device is constructed by acquiring the capacity of the target energy storage device that limits the regulation capability of the target energy storage device, so that the best power regulation effect can be achieved based on the achievable regulation capability of the target energy storage device.

[0056] Step 180: Substitute the power change rate of the target new energy machine group into the power regulation model for solution to obtain the regulated power of the target energy storage device.

[0057] In an embodiment of the present invention, the power change rate and power regulation model of the target new energy machine group are solved to obtain the optimal power regulation amount that can be achieved by the target energy storage device, thereby achieving effective regulation of the power of the target energy storage device and ensuring the stable operation of the power system.

[0058] The energy storage power regulation method proposed in the embodiment of the present invention divides the new energy units into groups, and divides the new energy units into nearby energy storage devices to realize power regulation nearby, thereby improving the flexibility of the power system; in addition, the power adjustment amount of the target energy storage device is determined by substituting the power change rate of the new energy group in the target energy storage device into the power regulation model, so as to realize that when a local new energy power disturbance occurs in the power system, the power change of the nearby energy storage device can be quickly adjusted, and the system frequency change caused by the new energy power change can be suppressed, thereby ensuring the stable operation of the power system.

[0059] In one embodiment of the present invention, step 120, taking the new energy units within the preset range of the target energy storage device as the target new energy unit group corresponding to the target energy storage device, specifically includes:

[0060] Step 210, taking the position where the energy storage device is connected to the bus as the starting position, and obtaining a target range of bus nodes that is a preset distance of m from the starting position.

[0061] Step 220, divide the new energy units within the target range of the target energy storage device into the target new energy group corresponding to the target energy storage device.

[0062] In an embodiment of the present invention, new energy units around each energy storage device are obtained to generate new energy groups corresponding to each energy storage device. For example, the position where each energy storage device is connected to the bus is taken as the starting position, the starting position is taken as the origin, and the range within m bus nodes from the starting position is taken as the adjustable target range of the energy storage device. The devices connected to each node within the target range of the energy storage device are traversed, and the new energy units are classified into the new energy group corresponding to the energy storage device. For example, the position where the target energy storage device i is connected to the bus is taken as the starting position, and starting from this starting position, the new energy units within the range of 5 bus nodes are all classified as the new energy group R corresponding to the target energy storage device i. i .

[0063] By dividing each new energy unit nearby, the new energy unit is assigned to a nearby energy storage device to achieve local power regulation and improve the flexibility and responsiveness of the power system.

[0064] In order to ensure that each new energy unit can be accurately divided into a corresponding area, an embodiment of the present invention further proposes a method for dividing new energy units. Specifically, Step 220, dividing the new energy units within the target range of the target energy storage device into the target new energy unit group corresponding to the target energy storage device, specifically includes:

[0065] Step 221: When there is a first new energy generating unit within the target range of multiple energy storage devices, the first new energy generating unit is divided into the new energy generating unit group corresponding to the energy storage device closest to it.

[0066] In the embodiment of the present invention, considering that there may be a new energy unit whose distance from two or more energy storage devices is less than m bus nodes, the new energy unit is divided into the new energy unit group corresponding to the energy storage device closest to it. For example, if the first new energy unit is 3 bus nodes away from energy storage device A and 4 bus nodes away from energy storage device B, the first new energy unit is divided into the new energy unit group corresponding to energy storage device A.

[0067] Step 222: When there is a second new energy generating unit within the target range of multiple energy storage devices, and there are multiple energy storage devices closest to the second new energy generating unit, the second new energy generating unit is divided into a new energy generating unit group corresponding to any one of the energy storage devices closest to the second new energy generating unit.

[0068] In the embodiment of the present invention, considering that there may be a new energy unit whose distance from two or more energy storage devices is less than m bus nodes, and there are multiple energy storage devices closest to the new energy unit, then the new energy unit is divided into the new energy unit group corresponding to any one of the energy storage devices closest to it. For example, if the second new energy unit has 2 bus nodes from energy storage device A, 3 bus nodes from energy storage device B, and 2 bus nodes from energy storage device C, the first new energy unit is divided into the new energy unit group corresponding to any one of the energy storage devices A and C.

[0069] Step 223: When there is a third new energy generator set that is not within the target range of any energy storage device, starting from the position of the third new energy generator set, search for the nearest third energy storage device, and classify the third new energy generator set into the new energy generator group corresponding to the third energy storage device.

[0070] In the embodiment of the present invention, considering that there may be a new energy unit that is no less than m bus nodes away from all energy storage devices, then start from the new energy unit and start searching for the energy storage device closest to the new energy unit, and divide the new energy unit into the new energy unit group corresponding to the energy storage device closest to the new energy unit. For example, if energy storage device A is 6 bus nodes away from the third new energy unit, energy storage device B is 8 bus nodes away from the third new energy unit, and energy storage device C is 6 bus nodes away from the third new energy unit, then the third new energy unit is divided into the new energy unit group corresponding to any one of the energy storage devices A and C.

[0071] The embodiment of the present invention ensures that each new energy device can find the best adjustable energy storage device, so that when power fluctuations occur in new energy units in a certain area, the corresponding energy storage device can respond in time, thereby improving the flexibility of power system operation.

[0072] In one embodiment of the present invention, step 140, obtaining the power change rate of the target new energy machine group, specifically includes:

[0073] Step 410, obtaining the output change of each new energy unit in the target new energy group corresponding to the target energy storage device.

[0074] Step 420, calculate the power change rate of the target new energy machine group according to the output change of each new energy machine group in the target new energy machine group.

[0075] In an embodiment of the present invention, the power of the energy storage device is adjusted according to the power change of the target new energy machine group corresponding to the target energy storage device. Specifically, a monitoring device can be installed in the power system to monitor and record the power change of each new energy machine group. Since there may be multiple new energy machines in the target new energy machine group corresponding to each target energy storage device, if you want to obtain the power of the target new energy machine group, you first need to obtain the power change of each new energy machine group in the new energy machine group, and then obtain the power change of the target new energy machine group according to the power change of each new energy machine group.

[0076] In one embodiment of the present invention, the power change rate of the target new energy machine group corresponding to the target energy storage device can be calculated by the following formula:

[0077]

[0078] Where ΔP i (t) is the target new energy fleet R within the preset change time i The power change rate, ΔP g For new energy fleet R i The output change data of each new energy unit in the , Δt is the preset change time.

[0079] In one embodiment of the present invention, step 160, constructing a power regulation model of the target energy storage device based on the capacity of the target energy storage device, specifically includes:

[0080] Step 610: Obtain the upper limit and lower limit of the regulation capability of the target energy storage device.

[0081] The acquisition of the upper and lower limits of the regulation capacity of the energy storage device usually requires consideration of multiple factors such as the technical parameters of the energy storage device, the operating status, and the actual needs of the power grid. The maximum output power of the energy storage device determines its maximum regulation capacity in the power system. The maximum output power is usually determined based on the capacity of the energy storage device, the energy storage technology, and the performance of equipment such as the inverter. The larger the capacity of the energy storage device, the more regulation energy it can provide, and thus the upper limit of the regulation capacity is higher. On the contrary, the minimum output power of the energy storage device determines its minimum regulation capacity in the power system. The minimum output power is also determined based on factors such as the rated capacity of the energy storage device, the energy storage technology, and the control strategy. The less the remaining capacity of the energy storage device, the lower the lower limit of the regulation capacity. It can be understood that the upper and lower limits of the regulation capacity of the target energy storage device constrain the power regulation size of the target energy storage device. Therefore, it is necessary to constrain the power regulation model of the target energy storage device by obtaining the upper and lower limits of the regulation capacity of the target energy storage device.

[0082] Step 620: Determine the power regulation constraint of the target energy storage device according to the capacity of the target energy storage device and the upper and lower limits of the regulation capability.

[0083] The power regulation constraint condition of the target energy storage device is determined through the self-regulation of the target energy storage device.

[0084] In one embodiment of the present invention, the constraint condition for power regulation of the target energy storage device is:

[0085]

[0086] In the formula, st is the constraint condition, u i (t) is the power value of the target energy storage device at time t, is the regulating capacity of the target energy storage device, Δt is the change time, s i is the capacity of the target energy storage device, is the lower limit of the regulation capability of the target energy storage device, is the upper limit of the regulation capacity of the target energy storage device, ΔP i (t) is the power change rate of the new energy cluster corresponding to the target energy storage device.

[0087] Step 630: construct a power regulation model of the target energy storage device based on the power regulation constraints of the target energy storage device and a preset objective function.

[0088] In the embodiment of the present invention, the power regulation model of the target energy storage device is:

[0089] min(f(t)-50) 2

[0090]

[0091] Where f(t) is the frequency of the energy storage device at time t, st is the constraint condition, and u i (t) is the power value of the target energy storage device at time t, is the regulation capability of the target energy storage device, s i Get the capacity for the target energy storage device, is the lower limit of the regulation capability of the target energy storage device, is the upper limit of the regulation capacity of the target energy storage device, ΔP i (t) is the power change rate of the new energy cluster corresponding to the target energy storage device.

[0092] Specifically, the objective function is to minimize the square difference between the frequency at time t and the target frequency of 50 Hz to suppress the frequency change of the energy storage device; the first constraint condition takes into account that the power of the target energy storage device cannot exceed the capacity of the target energy storage device at any time of operation; the second constraint condition takes into account that the regulation capacity of the target energy storage device cannot exceed the upper and lower limits; the third constraint condition takes into account the flexibility balance of the power system.

[0093] In one embodiment of the present invention, step 180, substituting the power change rate of the target new energy machine group into the power regulation model for solving, and obtaining the regulated power of the target energy storage device, specifically includes: substituting the power change rate of the target new energy machine group into the power regulation model, and using a preset optimization algorithm to solve the power regulation model to obtain the regulated power of the target energy storage device

[0094] By substituting the power change rate of the target new energy machine group measured in real time into the power regulation model for solution, the regulated power of the target energy storage device is obtained to adjust the power of the target energy storage device. In one embodiment of the present invention, the optimization algorithm can be a simulated annealing algorithm or a genetic algorithm, etc., and the optimal solution of the power regulation model, that is, the optimal power regulation amount of the target energy storage device, is determined by the algorithm.

[0095] In the embodiment of the present invention, a storage power regulating device is also provided, which can be referred to as Figure 2 , Figure 2 2 is a structural block diagram of an energy storage power regulation device in an embodiment of the present invention. The device includes a data acquisition unit 201 , a data processing unit 202 and a data analysis unit 203 .

[0096] The data acquisition unit 201 is used to take the new energy generator sets within a preset range of the target energy storage device as the target new energy generator group corresponding to the target energy storage device.

[0097] Obtain the power change rate of the target new energy fleet and the capacity of the target energy storage device.

[0098] The data processing unit 202 is used to construct a power regulation model of the target energy storage device based on the capacity of the target energy storage device.

[0099] The data analysis unit 203 is used to substitute the power change rate of the target new energy machine group into the power regulation model for solution to obtain the regulation power of the target energy storage device.

[0100] The energy storage power regulation device proposed in the embodiment of the present invention divides the new energy units into groups, and divides the new energy units into nearby energy storage devices to realize power regulation nearby, thereby improving the flexibility of the power system; in addition, the power adjustment amount of the target energy storage device is determined by substituting the power change rate of the new energy group in the target energy storage device into the power regulation model, so as to realize that when a local new energy power disturbance occurs in the power system, the power change of the nearby energy storage device can be quickly adjusted, and the system frequency change caused by the new energy power change can be suppressed, thereby ensuring the stable operation of the power system.
