Data-driven Robust Dispatch of Integrated Electricity-gas Energy Systems Considering Uncertainty of Wind Power

The interconnection of the electricity-gas integrated energy system is an effective way to improve renewable energy utilization efficiency. This paper constructs the optimal power flow(OPF) model and the natural gas network model. The main coupling parts of power system and natural gas system are gas-fired power unit (GFPU) and power to gas (P2G). In order to solve the problem, the power flow equation is transformed into a second-order cone and the natural gas network equation is linearized. Based on this, this paper proposes to apply robust optimization of data-driven to optimal power flow under the participation of wind power, and the model is improved on the basis of integrated 1-norm and ∞-norm. The final example analysis proves the validity and practicability of the model.
