本文提出一個新的功率潮流計算方法，可以容易地在輻射型或網目型的電力系統上快速且正確的完成功率潮流的計算，對具有PV匯流排的系統同樣正確有效。此方法是將搖擺匯流排電壓以等效電流源取代，將無負載網路導納矩陣之反矩陣預先完成，疊代時將負載功率在預設的電壓下轉化成負載電流，去進行下一次負載電壓的直接推算，反覆疊代直到收斂爲止。本方法分別在輻射型、網目型、有PV bus輻射型、有PV bus網目型等四種不同的系統加以測試，證實在各種系統都能快速收斂且有效求出正確的答案。

This paper present a new power flow calculation method, it can quickly and exactly solve the power flow problem in the radial or mesh type power system, including those with PV bus systems. This kind of method is to turn the slack bus voltage and the load power to the equivalent current sources, and direct calculate the bus voltage quickly and exactly. After testing at radial, mesh, radial with PV bus, and mesh with PV bus, 4 different type power systems, the results are all match those results of reference. Since the simplicity and easy programming this method would match the need of power flow calculation.
