Abstract

Abstract: With the technological development of integrated energy systems (IES) and the popularity of the shared energy storage system (SESS), the multiple integrated energy systems (MIES) would be gradually formed by several IESs and their interactions. The optimal operation of MIES with power and heat interaction considering SESS, optimization for equipment output in IES and adjustment for energy exchange among IES can reduce the operation cost of the whole MIES. Firstly, the optimal operation model for MIES considering the electricity and heat interaction is proposed on the basis of common equipment output of IES and SESS, where the electricity and heat interaction among each IES in MIES and external grid. Secondly, the model is solved by mixed integer linear programming method. In the numerical test, MIES consisting of three IES are taken as an example to analyze the economy of MIES which are connected to SESS considering power and heat interaction.

Key words: multiple-integrated energy system, optimal operation, power and heat interaction, shared energy storage system, mixed integer linear programming
