Robust Optimal Power Flow Model of Electricity-Gas Integrated Energy System Considering the Uncertainty of Roof Photovoltaic

With more and more distributed roof photovoltaic generators connected to the grid and their complementarity with gas turbines, which providing many possibilities for the coordinated operation of electricity-gas integrated energy system (IES). In this paper, aiming at minimize the total generation costs, a robust optimal power flow (ROPF) model was proposed for the electricity-gas IES connecting roof photovoltaic (PV) generators in the distribution network. Then, the proposed ROPF model is transformed into the mixed-integer second-order conic programming (MISOCP) model, which can be solved by Gurobi. The numerical simulations are carried on IG-30 system and IG-118 system to verify the applicability, safety and economy of the proposed ROPF model.
