Abstract

In view of the shortcomings of traditional stochastic programming and interval optimization methods for handling wind power uncertainty, a two-stage robust cooperative scheduling model for the electricity-gas integrated energy system with PtG facilities is proposed, and the influence of natural gas network operation constraints on the scheduling power output and reserve capacity configuration by gas-fired units and PtG facilities is considered. The sum of the day-ahead dispatch cost under wind power benchmark scenario and the real-time dispatch cost under the worst wind power scenario is regarded as the objective function, and a bi-level optimization model with max-min structure is established. Then the solution is obtained by using the column-and-constraint generation method through the master-sub problem solving framework. Finally, a simulation example is built on Mathlab platform to verify the effectiveness of the proposed two-stage robust cooperative scheduling model.
