摘要：Generating schedule power flow rapidly and accurately is an important step in security checking. In consideration of poor convergency property and calculating speed of conventional methods based on power flow calculations, this paper proposes a schedule power flow generating method based on state estimation to calculate schedule power flow. Pattern recognition is used to select similar section by comparing planned data and historical power flow to take the power flow of similar section as redundant measurements of state estimation. In state estimation calculation with transmission power constraints based on maximum correntropy criterion, measurements corresponding to generation schedule, load forecasting and maintenance schedule are assigned large weights. The schedule power flow calculated by the method could satisfy planned data conditions and transmission power constraints. Cases of IEEE 9-bus system and a practical power grid vertify the effectiveness and calculating accuracy of the method.
