摘　　要：文章对含有光伏、风电等微网系统的多储能形式的容量进行配置。首先,根据分布式电源及负荷的不确定性,确定微网系统中储电、储热、蓄冷3种储能形式的容量区间;其次,以微网经济运行成本最小为优化目标,以储能容量不越限为约束条件,保证微网向电网功率输出满足要求,求取各个储能形式的容量;最后,通过算例分析,验证最优容量配置与其他不同容量取值的优劣性,确定此方法在保证微电网系统经济运行的同时,有效提高微电网电能上网率。Reasonable allocation of energy storage capacity can ensure the micro grid economic operation,and effectively adjust the power transmission between microgrid and distribution network.In this paper,a kind of multi energy storage capacity allocation is proposed for microgrid systems with uncertainties such as photovoltaic and wind power generation.Firstly,micro network storage system,electric heat storage and cold storage of three storage capacity in the form of interval is determined according to the distributed power supply uncertainty;Secondly,the minimum operating cost of microgrid is regarded as the target,and the energy storage capacity is not limited as a constraint,the capacity of each energy storage type is taken to ensure that the microgrid can meet the requirements of the power output of the grid;Finally,through the example analysis,the optimal capacity allocation and other different capacity values are verified.It is confirmed that this method can effectively improve the micro grid power access rate while ensuring the economical operation of microgrid system.
