Multi-Objective Planning of Thermal-Electric Coupling Micro-Energy System to Promote the Consumption of Renewable Energy

Under the current integrated energy background, the development of thermal-electric coupling micro-energy system has become an effective solution to promote the consumption of renewable energy and sta bilize the fluctuation of renewable energy. Therefore, we propose a multi-objective planning method for thermal-electric coupling micro-energy system. First, on the basis of an analysis of the interaction characteristics of “source-grid-load” and its effect on the absorption of renewable energy in thermal-electric coupling environment, the equipment of thermal-electric coupling micro energy system is modeled. Then the multi-objective planning model of thermal-electric coupling micro-energy system is constructed with the aim of minimizing investment operation cost and system peak-valley fluctuation respectively, and then the multi-objective problem is solved by the combination of NSGA-II and TOPSIS. Finally, the simulation based on actual data verifies the rationality and feasibility of the proposed scheme.
