摘要
提高区域综合能源系统的运行经济性以及降低系统的碳排放量,提升对风光等清洁能源消纳能力和能源利用效率,考虑现有电转气技术的能量转换过程中热能损失问题,提出了新型包含回收热能再利用的电转热气方案,以系统运行总成本最小为优化目标,建立了含电转热气的区域综合能源系统模型.应用基于莱维飞行优化的粒子群算法以提高求解过程的收敛速度和准确性.最后,以北方某区域综合能源系统为算例,通过仿真结果验证采用电转热气模型有效提高了综合能源系统对清洁能源利用情况,降低系统的综合运行成本和碳排放量.
Abstract
In order to improve the economy of the combined Heat Gas Power supply regional integrated energy system and reduce carbon emissions,meanwhile to improve the consumption ability of clean energy and energy utiliza-tion efficiency,a novel Power to Heat Gas scheme included heat energy recovery and recycling is proposed in this pa-per,to solve the problem on the heat energy loss in the energy conversion process of current Power to Gas technology.Based on the above scheme,the regional integrated energy system model including the Power to Heat Gas model is es-tablished and the optimization goal is to minimize the total operation cost of the system.Then,the improved Levy-flight Particle Swarm Optimization algorithm is applied to improve the convergence speed and accuracy.Finally,a case study of a certain regional integrated energy system in North China is shown,and through the simulation results,the applicability of the proposed Power to Heat Gas model in the regional integrated energy system can improve the consumption of clean energy and reduce the operation cost and carbon emission of the system.
