Interaction Strategy of User Side Storage Devices for the Day-Ahead Dispatch of Distributed Integrated Energy Systems

Multi-energy complementarity is beneficial to reduce the operating cost and improve the reliability of energy systems. This paper presents an optimization framework for the day-ahead dispatch of distributed integrated energy system (DIES), to explore the interaction strategy of user side storage devices participating in the economic dispatch of DIES. Firstly, the model of DIES is established based on the concept of energy hub. Then, on this basis, the optimization model for the day-ahead dispatch of a DIES is built to achieve the lowest operation cost. Furthermore, the feasibility of the proposed method is validated by extensive cases studies. Results show that multi-energy complementary and energy storage devices can reduce the operating cost of energy systems effectively.
