Abstract

Abstract: Aiming at the problems of energy shortage and environmental deterioration caused by the current energy supply and consumption mode dominated by fossil energy such as coal, the optimal dispatching and operation of integrated electricity-gas energy system under the principle of power to gas (P2G) technology is studied by using the development and utilization idea of integrated energy system. By constructing the multi-objective cooperative optimization operation model of P2G participating in gas-electricity interconnected comprehensive energy system, based on the functional characteristics of P2G, such as carbon capture effect and gas-electricity coupling effect, multiple targets are processed with the help of cuckoo algorithm.The calculation results show that P2G equipment has the functions of effectively reducing wind rejection rate, peak load shifting and improving carbon emission reduction benefits, which provides a new way for renewable energy consumption.

Key words: gas-electricity interconnected comprehensive energy system, power to gas, consumption of renewable energy, multi-objective collaborative optimization
