Summary: | The invention discloses a DC power flow internal iteration method and system for power dispatching optimization, and relates to the technical field of power grid dispatching, and the method comprises the steps: obtaining system data in real time, and carrying out the data preprocessing; based on the obtained parameters, constructing a market clearing optimization model with the minimum total electricity purchase cost of the system as an optimization target; the direct current power flow is calculated through multiple iterations in the optimization model; and carrying out safety check by adopting a quasi alternating current power flow model, and incorporating an alternating current power flow result into direct current network constraint to further optimize direct current power flow iteration in the model. According to the method, the external alternating current safety check iteration process of the model is researched, and the alternating current and direct current power flow deviation caused by filtering se |
