摘要
工业用户对于微电网的应用有着极大的经济性和可靠性要求。可再生能源发电的不确定性,和储能充放电损耗过高,影响着微电网的经济性;同时,一般的微电网系统并没有备用储能,影响着微电网的可靠性。针对上述问题,提出了一种应用于工业微电网系统的分组储能控制策略。将储能分为三组分别进行优化调度,减少了可再生能源发电不确定性对微电网的影响,降低了储能蓄电池的充放电次数,提高了经济性,同时延长了断电情况下微电网对重要负荷的供电时间,兼顾到了微电网的可靠性。最后基于MATLAB平台进行仿真分析验证了该策略的合理性和有效性。
Industrial users have great economic and reliability requirements for the application of microgrid.The uncertainty of renewable energy power generation and the loss caused by the charging and discharging of energy storage battery in dispatching affect the economy of microgrid.At the same time,the general microgrid system has no standby energy storage,which affects the reliability of microgrid.In order to solve these problems,A group energy storage control strategy for industrial microgrid system was proposed.The energy storage was divided into three groups for optimal scheduling respectively,which reduced the impact of the uncertainty of renewable energy generation on the microgrid,reduced the charging and discharging times of energy storage battery,improved the economy,and extended the power supply time of microgrid to important loads in case of power failure,taked the reliability of microgrid into account.Finally,simulation analysis based on MATLAB platform verify the rationality and effectiveness of the strategy.
