Optimal Collaborative Planning with Demand Side Management in Integrated Gas-electricity Energy Systems

Power systems and natural gas systems have been tightly coupled and turn into integrated gas-electricity energy systems with the development of energy conversion technology. Demand side management (DSM) contributes to load leveling in power systems, and then is beneficial to the secure and economic operation of the integrated gas-electricity energy system. In this paper, a collaborative planning model with DSM in an integrated gas-electricity energy system is established. The operation framework of an energy coupling center is first proposed with three DSM schemes and the customer satisfaction well taken into account. Next, the optimal collaborative planning model is presented, aiming to minimize the total cost of construction, operation and DSM compensation. Finally, an integrated gas-electricity energy system including a 39-bus power system and a 20-bus natural gas system is employed to illustrate the feasibility and effectiveness of the proposed optimal planning model.
