含混合储能的独立微电网多时间尺度协调控制策略

提出了一种含混合储能的独立微电网多时间尺度协调控制策略。该控制策略采用“日前优化+日内滚动+实时控制”的方式，对各发电机组的启停和出力计划、负荷投切计划和储能系统的控制进行决策，并且不断修正。该策略可以有效地减轻预测误差带来的影响，从而提高含混合储能的独立微电网运行的稳定性与经济性。

Multi-time Scale Coordination Control Strategy of Isolated Microgrid With Hybrid Energy Storage

With the continuous improvement of the renewable energy penetration in the isolated microgrid,the prediction accuracy of renewable energy output have played more and more important role in the coordination control of the isolated microgrid.In addition,hybrid energy storage is introduced into the microgrid as a flexible and schedulable distributed resource,which can shift load and improve voltage quality.In the search of coordinated control of micro-grid,hybrid energy storage also has high adaptability in engineering.Therefore,this paper proposes a multi-time scale coordination control strategy for the isolated micro-grid with hybrid energy storage.The control strategy combines day-ahead optimization,intra-day rolling and real-time control to make decisions and continuous corrections on units'scheduling plan,load switching plan and energy storage system control.This strategy can effectively mitigate the impact of prediction errors,thereby improve the stability and economy of the isolated microgrid operation with hybrid energy storage.
