Modelling in Integrated Energy Trading System Under an Incentive-Compatible Market Mechanism

In recent years, carbon neutrality and sustainable development have become the key issue of social construction and development. The traditional single energy system can not meet the needs of energy sustainable development under the background of energy shortage because of its low energy efficiency. Multi-energy system generally includes electricity energy subsystem, thermal energy subsystem (heating and cooling), gas energy subsystem and other energy subsystems. The integrated energy system (IES) proposed in this paper integrates the energy of electricity, gas, heating, and cooling. At the same time, this paper proposes an integrated energy scheduling mechanism based on Vickrey-Clarke-Groves (VCG) auction. In the auction, users submit their energy demand data to the auctioneer, and then the energy hub (EH) provider completes the energy allocation through optimal scheduling, and decides the amount of payment of users, which proves that the auction mechanism has incentive compatibility property. It means that users will report their energy demand data. Cases studies are conducted to evaluate the energy optimization performance of the IES, and verify the economy of the auction mechanism.
