Abstract:

Multiheterogeneous energy storage technology plays an active role in the flexible operation and resource coordination of integrated energy systems. In this study, we propose a day-ahead game-robust optimization operation method for integrated energy systems considering flexible economic regulation of electric/thermal energy storage. This method taps the economic potential of electric/thermal heterogeneous energy storage in energy trading and the flexible potential under uncertain factors. First, an integrated energy system scheduling model and energy storage operation model are established considering the security constraints of state quantities such as node voltage and pipeline temperature. Then, under the framework of electric heating energy trading, the Stackelberg model and the MPEC form of the game between the integrated energy service provider and the prosumers are established considering the economic operation of energy storage. Next, based on the Stackelberg model, a two-stage robust optimization model is proposed considering the flexible intraday adjustment of battery energy storage and is solved by an improved column constraint generation algorithm. Finally, an example is given to verify the effectiveness of the proposed method. The flexible and economic regulation of energy storage can reduce the system operation cost and ensure the balance of intraday power supply and demand.

Key words: electrical/thermal energy storage, flexible economic regulation, integrated energy systems, prosumer, Stackelberg game
