Intraday Rolling Optimal Dispatch Considering Wind Power and Load Demand Uncertainty for Integrated Energy Systems

The integrated energy system can effectively promote the complementary advantages among energy sources, which are usually-presented random-like properties. To cope with the uncertainty of wind power and load demand, scenario analysis method is used for analyzing the uncertainty for optimal dispatching. The model predictive control is used to establish a closed-loop dynamic rolling. The results of day-ahead optimal scheme are as reference value to refine and correct the output of core coupling equipment in the short-term intraday scheduling. Finally, the modified IEEE30-node power system with a 10-node natural gas system and a 7-node thermal system is tested as an electricity-gas-heat integrated energy system. The test results turn out the correctness and validity of the intraday rolling optimal dispatch.
