Clearing for Coordinated Electricity and Gas Markets

In this paper, a new linear programming model is presented for Clearing of Coordinated Electricity and Gas Markets, so that Prices and decisions of electricity and gas networks are obtained in interactive competitive markets. These markets are cleared by their own market operator in coordination with other markets. The power market operator makes day ahead decisions based on a cleared gas market. The gas market is also affected by the decisions of the electricity market. In this model, the linearization of gas network constraints without integer and binary variables is introduced. Cleaning of coordinated and simultaneous electricity and gas markets has been solved using the duality theorem and KKT method. The proposed model is applied to a 6 bus test system and the IEEE 118-bus network. The results illustrate the effectiveness of the proposed model for the Clearing of the Coordinated Electricity and Gas Markets and the reduction of the operation costs and local prices of electricity and gas networks.
