摘要
传统储能容量配置方法未考虑SOC调整且配置容量偏大,为此建立一种在并网口处增设阻性负载的风电并网模型,并根据调整储能系统SOC的控制策略,使SOC尽量处于高位,在此基础上提出新的储能容量配置方法。以东北某风电场为例验证该方法的有效性和适用性,结果表明,新的储能容量配置方法可实现以少量电能的就地利用换取储能容量配置的大幅降低,且控制策略具有较好的控制特性。
The traditional approach for configuring capacity ignores the problems of excessive allocation and the adjustment of SOC, and for this reason, the paper proposed a model of wind power coupling by adding a resistance load at the grid connection point. In addition, this paper proposed a control strategy to improve the operation of energy storage systems through the adjustment of SOC which can maintain a high level of SOC, and proposed a new approach to deploying storage capacity based on this strategy. According to the analysis of a wind farm in Northeast China, this new approach of storage energy configuration method can exchange local utility of a little electrical energy for reducing the allocated capacity, and furthermore, this method also has better control characteristics.
