微电网鲁棒经济优化调度
Robust Economic Optimal Scheduling of Microgrid

受源荷预测误差与不确定性影响，微电网运行状态可能会发生大范围的波动，导致其运行出现问题。本文构建了考虑需求响应的微电网优化调度模型，提出一种基于鲁棒优化的经济调度方法。该方法以1 h为时间尺度间隔，采用鲁棒优化应对源荷预测误差，以解决经济调度计划不能适应微电网实际运行状态大范围波动的情况，使微电网满足运行状态。系统仿真验证了该方法的有效性。
Affected by the error and uncertainty of source and load prediction, the operation state of a microgrid may fluctuate in a wide range, resulting in problems in its operation. In this paper, an optimal scheduling model of microgrids considering demand response is constructed, and an economic scheduling method based on robust optimization is proposed. This method takes 1h as the time scale interval and adopts robust optimization to deal with the source-load prediction error, to solve the problem that the economic dispatch plan cannot adapt to the large-scale fluctuation of the actual operation state of the microgrid so that the microgrid can meet the operation state. System simulation verifies the effectiveness of the method.
