PROBLEM TO BE SOLVED: To provide a high speed and accurate state estimation method suitable for power system, using the hybrid measurement values of SCADA and PMU.SOLUTION: According to the method, voltages of the buses in a power system are determined. The values of the voltage includes a magnitude and a phase angle. Buses of the power system are grouped into a first area and a second area on the basis of the type of measurement values associated with each bus. The first area and the second area have at least one common bus, at least one bus in the first area is associated with a measurement value of the first type, and at least one bus in the second area is associated with a measurement value of the second type. Subsequently, the voltages of buses in the first area and second area are determined continuously according to the method. |
