Robust Stochastic Dynamic Optimal Power Flow Model of Electricity-Gas Integrated Energy System considering Wind Power Uncertainty

Abstract

The application of gas turbines and power to gas equipment deepens the coupling relationship between power systems and natural gas systems and provides a new way to absorb the uncertain wind power as well. The traditional stochastic optimization and robust optimization algorithms have some limitations and deficiencies in dealing with the uncertainty of wind power output. Therefore, we propose a robust stochastic optimization (RSO) model to solve the dynamic optimal power flow model for electricity-gas integrated energy systems (IES) considering wind power uncertainty, where the ambiguity set of wind power output is constructed based on Wasserstein distance. Then, the Wasserstein ambiguity set is affined to the eventwise ambiguity set, and the proposed RSO model is transformed into a mixed-integer programming model, which can be solved rapidly and accurately using commercial solvers. Numerical results for EG-4 and EG-118 systems verify the rationality and effectiveness of the proposed model.

Nonproportional Intentionally Mistuned Turbine Blisk Design with Improved Component Modal Synthesis

“…For instance, the high extremum outof-plane loads on the outlier robustness for wind turbines were discussed [24]. Some other scholars also studied the robustness of wind turbines, such as optimization efficiency and multiobjective robust optimization [25][26][27]. However, the robustness design of blades [28][29][30][31] had been focused since the beginning of the 21st century.…”
