Multi-objective Optimal Scheduling of Combined Cooling Heating and Power Generation Microgrid Containing Power to Gas

主要研究含电转气(power to gas,P2G)的冷热电联供(combined cooling,heating and power,CCHP)型微电网多目标优化调度模型。首先研究分析了CCHP型微电网结构及P2G工作原理,以运行成本和环境治理成本为目标建立含P2G的CCHP型微电网的多目标优化调度模型,然后运用基于帕累托(Pareto)最优解的多目标粒子群(multi-objective particle sware optimization,MOPSO)算法求解,最后算例分析验证了P2G可提高CCHP型微电网运行系统的弃风消纳能力,同时可提高系统运行的经济性和环保性。

This paper mainly studies the multi-objective optimization scheduling model of combined cooling heating and power(CCHP)microgrid containing power to gas(P2 G).Firstly,the structure of CCHP microgrid and the working principle of P2 G are researched and analyzed.The multi-objective optimal scheduling model of CCHP microgrid with P2 G is established with the objective of operating cost and environmental governance cost.Then,MOPSO algorithm based on Pareto optimal solution was applied to solve the problem.Finally,an example analysis verifies that P2 G can improve the wind abandoning capacity of the CCHP microgrid operating system,and at the same time can improve the economic and environmental protection of the system operation.
