Optimal Intraday Rolling Operation Strategy of Integrated Energy System with Multi-Storage

Traditional energy systems face the problems of low energy utilization rate, expensive energy cost and inaccuracy prediction of day-ahead renewable energy power output and load demand. On this account, an optimal intraday rolling operation strategy of integrated energy system (IES) is formulated in this paper. First, mathematical models of multi-type equipment in the IES are established and their operation character and energy flow character are analyzed. Then, the rolling strategy model is formulated aiming at minimizing the intraday operation cost of integrated energy system and giving equipment more economic and reasonable operation scheme. Case study result proves that with multi-storage the intraday rolling operation strategy of integrated energy system could improve economic efficiency and reliability of energy system effectively.
