Abstract
Provided is an optimized system voltage control method through coordinated control of reactive power source, which analyzes the location for reactive power compensation and the effect of applying compensation equipment by calculating the reactive power and voltage sensitivity of a power system, thus improving the voltage quality of the power system. The optimized system voltage control method includes verifying a voltage violation substation having a voltage exceeding a predetermined voltage reference value among buses of a test system on a computer program, configuring a local system with eight to ten substations with respect to the verified voltage violation substation, generating a reduced local system using a reduced local algorithm with respect to the buses within the configured local system, calculating a power flow by determining a voltage control amount for restoring the voltage of the voltage violation substation to a normal value with respect to the reduced local system, and calculating an optimization objective function value based on the voltage control amount and control operation.
