Research on System Planning of Gas-Power Integrated System Based on Improved Two-Stage Robust Optimization and Non-Cooperative Game Method

The power to gas (P2G) technology can realize the large-scale storage of electric energy in form natural gas, so that system and have ability flow energy, degree coupling between is deepened. As continues increase, an integrated (IES) with grid as core has emerged. However, under uncertain conditions, current planning methods still cannot guarantee optimal interests each manufacturer, a collaborative method for gas-electric systems based on non-cooperative game theory proposed. With unit electricity network companies independent interest groups, maximum annual net income optimization goal, establishing comprehensive non-combination wind turbines, electric-to-gas transmission lines pipelines linear programming model. Aiming at uncertainty load, improved two-stage robust Finally, modified IEEE 39-node 20-node verify application value model algorithm.
