Abstract

Aiming at the problem of renewable energy consumption, a comprehensive energy system coupled with power-to-heat equipment was established. The two day-ahead operation strategies of load following and cycle charging were used to optimize the system combined with grid search method. Sensitivity fo four constraints： radiation intensity, wind speed conditions, carbon tax cost and natural gas price was studied. The results show that the Integrated Energy System（IES） coupled with the power-to-heat equipment has better performance in terms of full-cycle life cost, energy cost, renewable energy penetration rate and annual carbon dioxide emissions; under the load following strategy, the system renewable energy penetration rate of system is 30.92%, and after coupling the power-to-heat equipment, the renewable energy consumption capacity is increased from 4.97% to 5.69%.

Key words
