Node Price Model Considering Gas-Electricity Coupled in Day head Integrated Energy Market

The low-carbon energy economy and high efficiencies has increased the concern about the energy system integration and integrated energy market. With the natural gas consumed of the power sector increasing, the natural gas system and electricity system have coupled strongly. In order to realize gas and electricity cleared at same time in a day-ahead market, we proposed a novel node price model for the coupled system. Considering the two markets coupled by gas-fired generations(GFG) and thermal load, we use the heat to build the link model between two markets. The applicability of proposed approach is verified by analyzing the node price of the typical nodes of a 6-bus power system with a gas system coupled at every bus. The result demonstrates the effectiveness of the proposed model, which provides a convenient way for market operators to clear integrated energy.
