Research on Multi-Timescale Coordinated Method for Source-Grid-Load with Uncertain Renewable Energy Considering Demand Response

The high penetration of renewable energy brings great challenges to power system operation and scheduling. In this paper, a multi-timescale coordinated method for source-grid-load is proposed. First, the characteristics wind forecasting demand response (DR) resources are described, framework presented under multi-timescale. Next, economic scheduling models based on DR network constraints established in process day-ahead scheduling, intraday real-time loads classified into three types terms different timescale. security grid side time-varying potential considered. Three-stage stochastic programming employed schedule source load day-ahead, intraday, markets. simulations performed modified Institute Electrical Electronics Engineers (IEEE) 24-node system, which shows notable reduction total cost an increase accommodation, their results proposed discussed against merely two timescales, demonstrates superiority quantity reduction.
