Optimal Operation of Regional Integrated Energy System Considering P2G with Heat Energy Recovery
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.
