Technical Field

[0001] This invention relates to the field of shared energy storage technology, and in particular to a shared energy storage power distribution method and system based on AGC scheduling commands. Background Technology

[0002] With the continuous increase in the grid connection scale of high-proportion renewable energy bases, the intermittent, random, and low-density characteristics of renewable energy power, as well as the large-scale centralized grid connection mode, have brought problems such as variable grid power flow, difficulties in system peak and frequency regulation, and low renewable energy utilization efficiency to the power grid. The power system faces severe challenges, and there is room for improvement in the utilization efficiency of renewable energy. Energy storage is a very effective means to solve the problem of "wind and solar curtailment." Through the flexible allocation of energy storage, release, and output by energy storage devices, it is possible to perform spatiotemporal energy shifting and smooth output fluctuations of renewable energy power plants, thereby improving the grid's acceptance capacity and reducing "wind and solar curtailment."

[0043] Figure 2 The schematic diagram of the shared energy storage power distribution method based on AGC scheduling instructions provided by the present invention. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The purpose of this invention is to provide a shared energy storage power allocation method and system based on AGC scheduling instructions, so as to realize the conversion and allocation of shared energy storage transaction results from electricity volume to power.

[0046] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1 The present invention provides a shared energy storage power allocation method based on AGC scheduling instructions, the allocation method comprising the following steps:

[0048] Step 101: Calculate the amount of abandoned electricity for each new energy power station participating in the shared energy storage transaction according to the AGC scheduling instructions.

[0049] Step 102: Calculate the total energy storage charging power of all new energy power stations participating in shared energy storage transactions at different times, based on the abandoned electricity and market transaction electricity of each new energy power station.

[0050] Step 103: Calculate the energy storage charging power of each new energy power station participating in the shared energy storage transaction at different times based on the total energy storage charging power.

[0051] Shared energy storage, as an innovative form of energy storage, is of great significance for improving the renewable energy absorption capacity of the power grid system. Its "1-to-N" trading characteristic places high demands on real-time power balance during the power allocation process. This invention aims to propose a shared energy storage power allocation and power calculation method based on AGC (Automatic Generation Control) dispatch commands, which can ensure that the shared energy storage trading results achieve the conversion and allocation of power from electricity.

[0052] This application proposes a method for power allocation and calculation based on shared energy storage, which is currently the most applicable peak-shaving ancillary service for shared energy storage. Addressing the issue of actual allocation and execution of electricity traded in the shared energy storage market, it combines parameters such as ultra-short-time power prediction of new energy power plants, AGC control power, and SOC of shared energy storage units. While considering power transmission losses, it establishes a method for shared energy storage power allocation and calculation based on AGC dispatch commands. The specific process is as follows: Figure 2 As shown.

[0053] like Figure 2 As shown, a preferred embodiment of the shared energy storage power distribution method based on AGC scheduling instructions of the present invention is as follows:

[0054] Process 1: Input Information. After the new energy power plant and grid-side shared energy storage complete market transactions at the power trading institution, the new energy power plant, grid-side shared energy storage, and the power trading institution will send input information to the energy storage control center, including parameters such as the new energy power plant's ultra-short-time power prediction, AGC control power, shared energy storage unit SOC, and market transaction results.

[0055] Step 2: Calculation of Curtailed Energy. The energy storage control center calculates the curtailed energy of each new energy power station within the grid-side shared energy storage trading period T, based on the AGC control power of the new energy power station. The calculation formula is as follows:

[0056]

[0057] Among them, Q abandon-i For the amount of abandoned electricity of the i-th renewable energy power station participating in the shared energy storage transaction, P AGC-i,k Let Δt be the AGC control power of the i-th new energy power station at the k-th time interval. There are n time intervals Δt within the trading period T.

[0058] Step 3: Power Allocation in a Trading Process. Based on the abandoned power volume of new energy power plants and the market-traded power volume, the trading power between shared energy storage and new energy power plants is calculated. This means that new energy power plants output more power than previously scheduled, and shared energy storage power plants charge at an equivalent power. First, the trading power ratio between the bid-winning power volume and the abandoned power volume of each new energy power plant is calculated. Second, the corresponding energy storage charging power of each new energy power plant is obtained by multiplying the trading power ratio by the AGC control power. Finally, the energy storage charging power is verified based on the SOC of the shared energy storage power plant. If the sum of the energy storage charging powers corresponding to all new energy power plants exceeds the maximum output power of the shared energy storage power plant, adjustments need to be made based on the maximum output power. The specific formula is as follows:

[0059]

[0060]

[0061] Among them, Q trade-i The electricity traded between the i-th renewable energy power plant and shared energy storage for electricity trading; m is the number of renewable energy power plants generating the trade; P sum-k P represents the energy storage charging power corresponding to all new energy power stations at the k-th time interval; max P represents the maximum output power of the shared energy storage power station. charge-i,k This represents the energy storage charging power of the i-th new energy power station at the k-th time interval after verification.

[0062] Step 4: AGC Command Update. Considering the physical distance between shared energy storage and new energy power plants that purchase services, line power transmission losses are introduced to correct the traded power, and this is used to update the AGC commands. The energy storage control center issues the updated AGC commands to the new energy power plants and shared energy storage units, and each power plant operates in accordance with the updated commands. The command update calculation formula is as follows:

[0063] P′ AGC-i,k =P AGC-i,k -P charge-i,k / (1+Lost i )

[0064] Among them, P′ AGC-i,k Lost is the updated AGC control power of the i-th new energy power station at the k-th time interval. i The line power transmission loss between the new energy power station i and the shared energy storage power station is given by the control center based on the grid structure.

[0065] Step 5: Calculation of Actual Transaction Electricity. Due to the maximum output power limitation of the shared energy storage power station during the electricity allocation process in Step 3, the market transaction electricity may not be fully realized. The electricity used for final settlement should be based on the actual amount. The formula for calculating the actual transaction electricity between the new energy power station i and the shared energy storage power station during the transaction period is as follows.

[0066]

[0067] The present invention also provides a shared energy storage power distribution system based on AGC scheduling instructions, the distribution system comprising:

[0068] The power curtailment calculation module is used to calculate the power curtailment of each new energy power station participating in the shared energy storage transaction based on AGC scheduling instructions.

[0069] The power curtailment calculation module specifically includes: a power curtailment calculation submodule, used to calculate the power curtailment based on the AGC control power of each new energy power station participating in the shared energy storage transaction in the AGC scheduling instruction, using the formula... Calculate the amount of abandoned electricity generated by each renewable energy power station participating in the shared energy storage transaction; where Q abandon-i P represents the amount of abandoned electricity generated by renewable energy power station i participating in shared energy storage transactions. AGC-i,k The AGC control power of new energy power station i participating in the shared energy storage transaction in the AGC scheduling instruction is represented by n at the k-th time interval Δt, where n represents the number of time intervals in the transaction cycle and Δt represents the time interval.

[0070] The total energy storage charging power calculation module is used to calculate the total energy storage charging power of all new energy power stations participating in shared energy storage transactions at different times, based on the abandoned electricity and market transaction electricity of each new energy power station.

[0071] The total energy storage charging power calculation module specifically includes: a total energy storage charging power calculation submodule, used to calculate the total energy storage charging power based on the abandoned electricity and market-traded electricity of each new energy power station using the formula... Calculate the total energy storage charging power of all new energy power stations participating in shared energy storage transactions at different times; where P sum-k Let Q be the total energy storage charging power of all new energy power stations participating in the shared energy storage transaction at the k-th time interval. trade-i Q represents the electricity traded between a new energy power station i participating in a shared energy storage transaction and a shared energy storage power station. abandon-i P represents the amount of abandoned electricity generated by renewable energy power station i participating in shared energy storage transactions. AGC-i,k The AGC control power of renewable energy power station i participating in the shared energy storage transaction in the AGC scheduling instruction is represented by m, which represents the number of renewable energy power stations participating in the shared energy storage transaction.

[0072] The energy storage charging power calculation module is used to calculate the energy storage charging power of each new energy power station participating in the shared energy storage transaction at different times based on the total energy storage charging power.

[0073] The energy storage charging power calculation module specifically includes: an energy storage charging power calculation submodule, used to calculate the total energy storage charging power using the formula... Calculate the energy storage charging power of each new energy power station participating in the shared energy storage transaction at different times; where P charge-i,k Q represents the energy storage charging power of new energy power station i participating in the shared energy storage transaction at the k-th time interval. trade-i Q represents the electricity traded between a new energy power station i participating in a shared energy storage transaction and a shared energy storage power station. abandon-i P represents the amount of abandoned electricity generated by renewable energy power station i participating in shared energy storage transactions.

[0074] To improve the reliable execution of shared energy storage in the electricity market, this paper proposes a method for power allocation and calculation of shared energy storage based on AGC dispatch commands, addressing the issue of converting grid-side shared energy storage transaction volume into electricity. The main technical advantages of this proposal are as follows:

[0075] (1) Based on the predicted abandoned electricity and market transaction electricity of new energy power plants, this invention converts electricity into power through proportional allocation. At the same time, it takes into account the maximum output power of energy storage power plants and verifies and adjusts the allocated electricity to ensure the simplicity and feasibility of converting transaction electricity into power.

[0076] (2) The shared energy storage service in this invention is established on the grid side. Since there is a certain electrical distance between the new energy power station participating in the peak shaving service and the shared energy storage power station, there will be losses in the electricity trading. Therefore, this solution corrects the trading electricity by introducing line power transmission loss, thus ensuring the fairness of the grid-side shared energy storage peak shaving service.

[0077] (3) The shared energy storage trading electricity metering in this invention takes into account the situation where the shared energy storage power station is limited by the maximum output power, resulting in the inability of all trading electricity to occur. The actual trading electricity is calculated before and after the AGC control command is updated to ensure the reliability of electricity market transactions.
