Coordinated Operation of Multi-Integrated Energy System Based on Linear Weighted Sum and Grasshopper Optimization Algorithm

Abstract

Aiming at tapping the potential of energy complementary, maximizing renewable energy sources utilization and jointly minimizing the operating cost, a coordinated operation model of a multi-integrated energy system based on linearized coupling relationship is established in this paper. In order to establish an accurate model for interconnected energy hubs, an integrated strategy is proposed by the combination of the linear weighted sum and grasshopper optimization algorithm to solve the energy management problem, which improves comprehensive energy efficiency and realize regional coordination optimization. Eventually, the case study indicates that the operating cost of the multi-integrated energy system with coordination is reduced by nearly 3.2%, which can effectively validate the scalability, flexibility, and economic performance of the presented integrated strategy.
