Research On The Day-ahead Economic Dispatch Method of Microgrid Including Solar-ESS-EV
摘要
Abstract
In order to improve the power supply reliability and energy utilization rate of microgrids,a day-ahead economic optimization scheduling method considering time-of-use electricity prices is proposed.First,the power or energy model of photovoltaic,energy storage system(ESS),electric vehicles(EV)and other entities is established,and then the photovoltaic power model and Bi-LSTM model are used to predict the photovoltaic and conventional load power during the day,respectively.Combined with the flexible load characteristics of electric vehicles,the objective function is established to minimize the total system operation and maintenance cost(including equipment operation and maintenance cost,external network power cost,energy storage battery attenuation cost,etc.)and the charging cost of electric vehicles.Considering the multi-objective and high-dimensional characteristics of the optimization problem,a linear programming solver is used to solve the objective function.Finally,the historical operational data of a microgrid in an industrial park with solar-ESS-EV for the whole year of 2021 is selected,and the conventional load and photovoltaic power prediction model proposed in this paper is first tested.Then,according to the matching difference between photovoltaic output and conventional load,four typical daily scenarios are selected to test the control algorithm proposed in this paper.The results prove the effectiveness of the power prediction model and economic scheduling algorithm in this paper.关键词
