A static security online decision support optimization model is proposed based on the smart grid dispatching and control system platform. In view of the inadequacy of the current online system decision support application

problems are analyzed and the characteristics of the provincial power grid are referred to prior to adoption of new modeling principles and frameworks. A static security decision support model based on multiple control measures and constraints is developed and parameter optimization methods are discussed. Not only optimization objectives and control methods are enriched

but also control constraints are refined by the model. Higher feasibility and better optimization of decision support based on the model is achieved by simulation.
