摘要
Abstract
It is difficult for independent energy storage to recover costs by only participating in the spot electricity market.Participation in both the spot and frequency regulation ancillary service markets will become a future trend.Due to the coupling of the two markets,independent energy-storage operators need to develop a reasonable market participation strategy to maximize returns.Considering the current price mechanisms and settlement mechanisms of power consumption of independent energy storage,based on the market rules of spot and primary frequency modulation,a joint optimization model of independent energy storage participating in spot and primary frequency modulation auxiliary service market at the same time is proposed and solved using mixed integer linear programming.Using the spot market price of a node in PJM and the data of Shanxi independent energy storage participating in a frequency modulation trial operation,an example is designed to analyze the cost and income composition of independent energy storage participating in different markets and different frequency modulation power ceilings,analyze the changing trend of daily cycle times of energy storage under different frequency modulation declared power,and compare the influence of transmission and distribution price and fund surcharge caused by power loss on the cost.Under the current market rules,independent energy storage power stations that use more than 2 h can significantly improve their income level and reduce life loss by simultaneously participating in spot and primary frequency modulation markets.The transmission and distribution price,government funds,and additional electricity charges costs caused by the loss of electricity can account for more than 20%of the operating cost of energy storage.关键词
