摘要
针对高穿透率的分布式发电系统,搭建了一种储能电池—超级电容器混合储能系统,介绍了分布式发电系统的模型以及混合储能单元的模糊自适应控制的原理。为保证混合储能设备的荷电状态的可靠性,提出一种模糊自适应控制及时修正混合储能设备的功率参考值,优化储能设备的充放电过程。对有无模糊自适应控制两种情况进行仿真,结果表明混合储能能够有效平滑分布式发电系统并网有功功率,并延长储能设备的使用寿命。
A battery-supercapacitor hybrid energy storage system is established for the construction of high penetration rate distributed generation system（DGS）,thus the model of DGS and the adaptive fuzzy controlling principles of the hybrid storage system are presented in this paper.In order to ensure the load reliability of the hybrid energy equipments,a power parameter of fuzzy controlling and adaptive to the hybrid energy storage equipments is devised so as to optimize the charge/discharge process of the equipments.Then simulations have been made on the conditions of with/without the fuzzy adaptive control system,and the result shows that the hybrid energy storage system can effectively streamline the active power of the DGS in grid and therefore increase the service life the energy storage system.
