SYSTEM FOR CONTROLLING VOLTAGE AND REACTIVE POWER IN ELECTRIC POWER SYSTEM CONNECTED WITH DISTRIBUTED GENERATION AND METHOD FOR THE SAME

摘要

PURPOSE: A voltage/reactive power control system of an electric power system and a method for the same are provided to enhance accuracy of voltage control by accurately producing voltage size. CONSTITUTION: A voltage output part(710) produces the voltage of a node by using at least one among voltage, current, and power factor of an adjacent node. A control variable output part(720) produces a value of a control variable by using an objective function including one or more control variables in order to control the produced voltage. A controller(730) controls distributed power according to the value of the control variable with the other control device. The distributed power is composed of at least one among wind power generation, solar power generation, and a fuel battery.
