摘要(Abstract)：

针对混合储能系统中能量型和功率型储能的不同特点,建立了符合实际需求的微网经济优化模型。根据不同时间尺度提出了日前调度策略和实时调度策略。考虑到日前调度预测精度差的弊端,应用机会约束规划,以一定置信水平下满足备用需求作为可靠性约束,将最小运行成本作为优化目标,利用分时电价差异,优化协调各微源和储能系统出力。针对微网内风机、光伏和负荷等不确定性因素带来的功率波动,实时调度中应用1阶低通滤波算法平滑波动功率,并通过滑动平均滤波方法对滤波后的波动功率在混合储能中进行合理分配,使蓄电池储能承担更多低频功率波动,超级电容器承担高频波动。实时调度按照日前计划进行,实时监测各单元运行状态,并及时修正功率波动累积引起的日前计划偏差。
