Multi-time Scale Coordinated Dispatch Optimization Method for Power System With Large-scale Wind Power Grid-integrated Based on Interval Prediction
摘要
Abstract
The integration of intermittent,clustered wind power into the grid will increase the risk of the over-limit power transmission sections,and the incorporation of point prediction information into the dispatch of power systems containing wind power will inevitably result in"over-dispatch"and"under-dispatch".Therefore,a multi-timescale coordinated dispatch approach of wind power cluster based on interval model prediction control is proposed.First,a wind power interval prediction model is developed via using the point prediction model and its prediction error distribution.Second,a wind farm power dynamic grouping strategy with interval prediction information is established.Then,a multi-timescale coordinated dispatch strategy for wind power clusters and automatic generation control(AGC)units and non-AGC units is proposed.Finally,the effectiveness of the proposed method is verified by using actual wind power cluster data and a modified IEEE-118 standard test system.The results show that the proposed method could reasonably coordinate the individual wind power output and the output power of the wind power cluster,AGC units and non-AGC units.关键词
