Time-of-Use Pricing Strategy of Integrated Energy System Based on Game Theory

The integrated energy system is the mainstream utilization form of integrating a power system, natural gas and thermal which provides new way to solve problem renewable accommodation. includes variety generation conversion equipment, its internal electricity, gas, cooling systems must balance multiple supplies required by users. supplier (IES) user (IEU), as different stakeholders, pursue maximization their own profit. However, suppliers should consider market share sustainability participating in competition. Based on constraints access, accommodation, equipment for generation, consumption, we established an flow model. Constrained dynamic equilibrium supply demand users, Stackelberg game model users was established, existence Nash solution proved. A genetic algorithm used under two conditions aiming at supplier’s maximum profit target Considering time periods, analyzed time-of-use pricing strategy based demand. results case study show that if adopt profit, load distribution can be smoothed, economic benefits improved. If enlarge limiting obtain purchase willingness reducing price, they have larger share, more reliable guarantee long-term participation transactions.
