Abstract
In the view of marketing, an electricity-natural gas-heat multi-energy day-ahead market on the le-vel of IES(Integrated Energy System) is built, and the basic trading mechanism of LA(Load Aggregator) participating in multi-energy day-ahead market is elaborated. Then, an IDR(Integrated Demand Response) model in the multi-energy market is established, and the optimal joint trading strategy among electricity, na-tural gas and heat is analyzed by taking the maximum profit of LA as the optimization objective. The network model of electricity-natural gas-heat IES is established to ensure that the market transactions satisfy the requirement of safe operation of IES. The effectiveness of the proposed method is verified with an IES composed of an IEEE 33-bus power system, an 11-node gas system and a 6-node heat system. Comparison results between traditional DR(Demand Response) and the proposed IDR model in multi-energy market validate that the proposed IDR model can not only increase gross profit of LA, but also fulfill different types of energy demands and suppress load fluctuation via peak-valley complementary of multi-energy.
