Capacity coordination planning model of wind solar storage hybrid power system

Abstract

Based on the daily and monthly characteristics of wind power and photovoltaic output, the wind power / photovoltaic sequence model based on the daily and monthly characteristics is constructed. Considering the generation constraints, energy storage constraints, system power balance constraints and renewable energy consumption rate constraints of each unit, the coordinated optimization planning model of wind photovoltaic storage complementary power system capacity is constructed to determine the different renewable energy consumption rate fields The optimal capacity of wind power, photovoltaic and energy storage. The results show that the optimal installed capacity of wind power, photovoltaic power and energy storage is different under different scenarios of renewable energy consumption rate and tie line utilization rate, but the impact of energy storage capacity is small.
