“…Aiming at the participation of energy storage system in frequency modulation of power grid, literature [1] studies the participation of battery energy storage in secondary frequency modulation of power grid, proposes a control strategy of secondary frequency modulation of power grid and verifies its feasibility. Literature [2] describes the randomness of frequency modulation demand of hybrid energy storage through Markov chain, and proposes a stochastic model predictive control method for effective energy management of hybrid energy storage.…”

With the "double carbon" goal proposed, the application of renewable energy with clean and low-carbon characteristics in the power grid has been paid more and more attention. Firstly, the value evaluation system of independent energy storage participating in frequency modulation is proposed for compressed air energy storage, lithium iron phosphate battery energy storage and allvanadium flow battery energy storage. Secondly, the proposed value evaluation system is designed based on the least square method to assign weights to subjective and objective indicators, which is more objective and reasonable. After that, the matter-element extension theory is used to evaluate the proposed index system. By establishing the correlation between "pollutant reduction" and "renewable energy consumption contribution" and other indicators, this paper obtains the comprehensive value of independent energy storage participating in the frequency modulation market from multiple perspectives. Finally, according to the actual operation data of Mengxi power grid, the results show that the method can accurately measure the value of independent energy storage participation in frequency modulation, and can accurately measure the advantages and disadvantages of various types of energy storage participation in frequency modulation market indicators.
