Abstract
Microgrid has become the research focus of power and energy worldwide owing to its flexibility and economic efficiency,and the realization of islanded operation is one of its important characteristics. In this paper,a reliability evaluation method for microgrid in islanded operation mode is proposed to predict the data of wind power and photovolta?ic power generation and coordinate loads. First,the prediction model and power model of different distributed genera?tions in the system are established,and measures such as the remaining power of energy storage equipment and the pre?diction of power generation are taken to guarantee the key load power supply a priority. Then,the prediction data are used to distribute loads during the islanded operation;simulations are conducted on the modified DRTS Bus 4 test sys?tem using the sequential Monte Carlo method and statistical data are collected,which verifies the effectiveness of the proposed method. Simulation results show that the power supply reliability index of key load is improved obviously un?der the load coordination strategy.关键词
