Abstract
With the rapid development of renewable energy,its intermittency and instability pose challenges to the power grid.However,the construction of energy storage systems can significantly enhance the regulation capacity of the power system.By using the system dynamics model,various revenue sources of the energy storage system are analyzed,including peak-valley arbitrage,self-consumption of new energy,smoothing output,capacity compensation,and lease income,etc.,and profit and loss factors such as charging loss,green certificate gains and losses,and allocation of ancillary services are also considered.The results show that the economic benefits of energy storage mainly come from rental fee income and peak-valley arbitrage income.Meanwhile,as the cost of energy storage decreases,the net profit remains stable.It is expected that the income will be recouped in the 6th to 7th years,and the cumulative net income in the 10th year can reach 450 million yuan.The research provides a reference for the economic analysis of energy storage facilities built in conjunction with new energy,which is conducive to promoting the application of energy storage systems on the power generation side of new energy.关键词
