摘要：
The reasonable capacity configuration of wind turbine, PV (PhotoVoltaic) and energy storage in a microgrid is the prerequisite of its reliable and economical operation. For the grid-connected microgrid, two commercially operating modes are proposed according to the existing operating mode of distributed PV system. A comprehensive energy dispatch strategy is designed to fully use the resources of power distribution network and enhance the islanding ability of microgrid. For the objective function of a wind-PV-storage capacity configuration model comprehensively considering the economy, reliability and renewable energy usage rate of microgrid, a calculation method combining with the operating mode and dispatch strategy is proposed. For the engineering applications, a method for calculating the power limit of tie line to meet the operational specifications of power system and the friendly connection conditions of microgrid is elaborated, which is used as the constraint of the configuration model. An improved genetic algorithm based on the limited searching area and increased random individuals is presented to solve the configuration model. A simulative analysis is carried out based on the wind-PV resource data of an island in Jiangsu province to verify the effectiveness and superiority of the proposed PV-wind-storage capacity configuration method. © 2016, Electric Power Automation Equipment Press.
