Abstract

Abstract:

With the rapid development of the power industry,renewable energy sources are gradually connected to the grid on a large scale.Since the development of thermal power units is limited by severe pollution problems,the proportion of renewable energy in the power generation mix gets increased to a certain extent.Wind power generation,while reducing pollution and improving system economy,has problems in practice,such as randomness and intermittency.And its large-scale application is restricted by the uncertainty of wind power output and the high cost of energy storage systems.The strategy of wind power's participation in electricity market and the operation optimization of wind-energy storage systems are analyzed.The main processes are as follows.Firstly,the development background and practical importance of the subject are introduced.Subsequently,the structure and principle of the hybrid wind-storage system,and the strategy and risk factors of wind power participating in electricity market are analyzed.The hybrid wind-storage system aims at maximizing the total revenue.Taking the fluctuations of wind power output and electricity price into consideration,a target model for optimizing the demand-side energy storage system is established.Finally,based on the mathematical model,and the optimization strategy is made.

Key words: wind power, energy storage system, demand side load, electricity market, renewable energy, new power system, energy internet
