【摘要】：提出一种含分布式电源地区电网孤岛模式下储能设备的优化配置方法,首先监测每个时间点分布式电源出力和负荷数据并分别拟合出其概率分布函数;其次建立储能设备充放电的控制策略得到储能设备输出功率的控制规则;接着建立分布式电源与负荷的动态半不变量,得到储能设备的充放电功率的概率分布;最后建立以储存设备容量最小化为目标,储能设备的荷电状态以及满足一定的置信区间作为不等式约束条件的配置优化模型,并求解得出储能设备的配置容量。仿真结果表明,该方法能够解决永久性故障情况下区域电网孤岛模式稳定运行和经济性问题。
[Abstract]:An optimal configuration method for energy storage equipment in isolated island mode of power grid with distributed power supply is proposed. Firstly, the load and output data of distributed power generation at each time point are monitored and their probability distribution functions are fitted respectively. Secondly, the control strategy of charging and discharging of energy storage equipment is established, and the control rules of output power of energy storage equipment are obtained. Secondly, the dynamic semi-invariant of distributed power supply and load is established, and the probability distribution of charge and discharge power of energy storage equipment is obtained. Finally, a configuration optimization model with the goal of minimizing storage capacity, charging state of energy storage equipment and satisfying certain confidence interval as inequality constraints is established. The simulation results show that this method can solve the problem of stable operation and economy of isolated island mode of regional power network under permanent fault.
