A Two-Stage Multi-Objective Optimal Scheduling Model for Community Integrated Energy System

Abstract

Community integrated energy system coupled with renewable energy generation provides an effective solution to improve economy and reduce carbon emissions. This paper establishes a two-stage multi-objective optimal scheduling model for community integrated energy system. During the day-ahead scheduling stage, a comprehensive customer dissatisfaction model based on Kano model is established, and the model takes total operating cost, comprehensive customer dissatisfaction, and carbon emissions as multi-objectives. The Non-dominate Sorting Genetic Algorithmic-II (NSGA-II) and the CRITIC-TOPSIS evaluation model are used to develop a day-ahead scheduling scheme. On the premise of ensuring customer dissatisfaction, the intra-day scheduling stage evens out the uncertainty of wind power and photovoltaic power through rolling optimization and improves the reliability of system operation. Simulation results show that the proposed model reduces the total operating cost and carbon emissions by 8.1% and 12.8%, respectively, which validates the effectiveness of the proposed model. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
