Abstract:

With the grid connection of large-scale renewable energy,the fluctuation and randomness of wind power output need sufficient flexibility resources to meet its grid connection needs.Firstly,the grid connected active power regulation requirements of wind farms are analyzed.Considering the output characteristics and economy of multi-scale flexible resources,an optimization model of wind farm energy storage capacity under multi-scale flexible resource game is proposed.Secondly,NashQ algorithm is used to solve the multi-scale flexible resource game problem and the learning rate of each agent is adaptively optimized,which can improve the convergence speed of the algorithm.Finally,the effectiveness of the proposed model and method is verified by simulation.

Key words: wind power grid connection, optimization of energy storage capacity, multiple time scales, Nash equilibrium, adaptive learning rate
