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. 本发明公开了种基于灵敏度因子的电网节点边际电价计算方法，包括以下步骤：确定节点边际电价的计算周期，获取电网的灵敏度因子，建立基于灵敏度因子的电力市场出清优化模型，采用线性规划方法求解模型，计算出约束条件的影子价格，最终生成电网节点边际电价的出清结果。本发明计算效率较高，适用于求解大规模电网的市场出清问题。
