Optimal Allocation of Energy Storage System Capacity of Wind- photovoltaic-storage Microgrid Considering Carbon Revenue

Distributed energy resources such as wind power and photovoltaic power have the characteristics of intermittency and volatility, and energy storage technology can effectively reduce the fluctuation of output power and improve energy controllability. Based on the analysis of the output characteristics of wind-photovoltaic-storage microgrid, this paper establishes the wind- photovoltaic -storage microgrid with the minimum total cost of wind- photovoltaic -storage microgrid as the optimization goal capacity-optimized configuration model. The total cost takes into account construction costs, operation and maintenance costs, and carbon trading benefits; constraints include investment decision constraints and operational simulation constraints. For this model, the immune genetic algorithm (IGA) is used to solve the model, and finally the data of wind- photovoltaic -storage microgrid in a certain area are used for simulation verification, and the results prove the effectiveness and feasibility of the model.
