响应电网调度需求的光伏发电系统建模及运行控制研究
Research on modeling and operation control of photovoltaic generation system on response to grid dispatching requirements
摘要
Abstract
Aiming at the problem of the lack of executing power grid dispatching instruction in the existing photovoltaic (PV) simulation model, the method of the modeling and operation control of photovoltaic generation system on response to grid dispatching requirements was proposed. According to the composition structure of PV system with different capacity, the simulation model of grid connected PV generation system with different capacity based on DIgSILENT was built. The aim was to minimum the response?time of photovoltaic generation system in response to grid active demand considering the randomness of the photovoltaic generation system output. The demand of power grid dispatching was responded by adjusting the DC voltage control signal. The condition of the frequency constraint of power grid connected point is satisfied by the active power output limit module. The MPPT control strategy was optimized by the conductance increment method. The simulation results show that the constructed model could quickly respond to the power grid dispatching order, while without the demand of power grid dispatching, the model could achieve the maximum power tracking or limit active power output to meet the frequency constraint condition.关键词
