Multi-objective coordinated optimization model for integrated energy systems with power-to-gas and combined-cooling-heating-power technologies
Both net income of system and energy curtailment rate of renewable energy are the problems that the integrated energy systems mainly focus on. On the basis of combing the current research, this paper firstly designs a coordinated optimized operation structure for integrated energy systems considering the equipment such as power-to-gas (P2G) unit, combined-cooling-heating-power (CCHP) unit and electric refrigerator. Secondly, a multi-objective optimization model for the coordinated operation of system is built with the aims of maximizing system revenue and minimizing energy curtailment, as well as the unit modelling and constraints, and the multi-objective particle swarm optimization algorithm is applied to solve the proposed model with integration of the fuzzy comprehensive evaluation method. Finally, four energy conversion scenarios are set for example analysis. Combined with the comparison of the results of the four scenarios, it can be concluded that the introduction of diversified energy conversion equipment brings a certain increase in depreciation cost and operation cost, but significantly improves the utilization rate of clean energy, as well as improves the energy efficiency, which effectively proves the advanced nature of the multi-energy cooperative optimization system.
