The specific technical effect is mainly shown for case data, and the model in the method is solved by calling Gurobi.
And (3) operating environment:
AMD Ryzen 53400G CPU 3.70GHz, 16GB memory, Microsoft Windows 10X64
Gurobi 9.0.3
MATLAB 2020B
The implementation results are as follows:
the application example is based on the pilot run data of the Zhejiang electric power spot market in a month, and comprises day-ahead node electricity price, real-time node electricity price, frequency modulation auxiliary service capacity compensation electricity price and mileage compensation price data. In the embodiment, the construction scale of the energy storage power station is 100MW/200MWh, the upper limit and the lower limit of SOC are respectively 0.9 and 0.1, the interval time is 1h, and the discount rate is 0.

And formulating a two-stage regulation and control strategy under the peak-shaving frequency modulation mode of the energy storage power station under the background of the spot market through a maximum profit optimization model, and taking the two-stage regulation and control strategy as a profit evaluation reference of the energy storage power station.
Fig. 1 is a flow chart of a method for making a regulation and control strategy of an energy storage power station, and the method comprises two stages of a day-ahead market (DAM) and a real-time market (RTM).
FIG. 2 shows the data of the price of fresh electricity produced by the electricity spot market in Zhejiang on a trial run at a certain day.
Fig. 3 reflects the day-ahead market regulation and control strategy of the energy storage power station and the electricity change condition of the energy storage power station in the peak-shaving frequency-modulation mode, and fig. 4 reflects the real-time market regulation and control strategy of the energy storage power station and the electricity change condition of the energy storage power station in the peak-shaving frequency-modulation mode. The compensation price of the frequency modulation auxiliary service is higher, the income proportion from the frequency modulation service is higher, and the charging and discharging power of the energy storage power station in the electric energy market can change due to the difference between the real-time market electricity price and the day-ahead market electricity price. In addition, because the frequency modulation service simultaneously has the frequency modulation upwards and the frequency modulation downwards, the electric quantity of the energy storage power station changes relatively little when the frequency modulation service is involved.
FIG. 5 reflects the income distribution condition of a typical day of participation of the energy storage power station in DAM, and the average value of profit of the energy storage power station in the market of the typical day through time-of-use electricity price peak valley is 15899 yuan; fig. 6 reflects the profit distribution of the energy storage power station participating in RTM on a typical day, which is 248425 yuan by the average value of peak shaving and frequency modulation auxiliary service profit in the real-time market.
According to the results of the embodiment, the energy storage power station has higher frequency modulation market compensation price, so the energy storage power station mainly participates in frequency modulation auxiliary service arbitrage and supplements the electric quantity of the energy storage power station through the electric energy market. In addition, due to the fact that the day-ahead market node electricity price and the real-time market node electricity price are different, modification of day-ahead electric energy market bidding is beneficial to the energy storage power station to obtain higher expected income in the real-time market, and therefore the requirement that the energy storage power station participates in various application scenes under the background of electric power spot goods is met, and the economical efficiency of the energy storage power station is improved.
Therefore, the energy storage power station regulation and control method can specify the energy storage power station scheduling strategy meeting the power spot background, further effectively schedule the energy storage power station, provide basis for the scheduling of the energy storage power station, and improve the economy of the energy storage power station.
