Abstract | The invention discloses a sensitivity factor based calculating method for power grid node marginal pricing. The method is performed through the following steps: determining the calculating period for node marginal pricing, obtaining the sensitivity factors of a power grid, building a power market clearing optimal model based on the sensitivity factors, adopting a linear programming method to solve the model, calculating the shadow price under constrained conditions and finally generating the clearing result of the power grid node marginal pricing. According to the invention, high calculating efficiency can be achieved. The method is suitable for addressing the market clearing problems in a large-scale power grid.
