Stability Constrained Two-Stage Robust Optimization Model for Microgrid Economic Dispatching

Abstract With the development of high penetration renewable energy, power system has faced a big challenge low inertia and weak frequency support. This paper proposed two-stage robust mathematic optimization model with three layers to cope uncertainty in microgrids considering constraints. The controllable generators microgrid were modeled, including gas turbine, energy storage, demand response. uncontrollable photovoltaic wind turbine are described an set that can be observed by weather forecasting errors. Second, economic dispatching constraint reasonably arrange startup shutdown plan units, decrease change rate after disturbance, improve inertial response ability system. Finally, case study results show effectiveness model.
