Abstract
Maintaining the voltages is important in the power systems and the voltage is closely associated with the reactive powers. Therefore, the voltages are maintained by controlling the reactive powers. However actually it is impossible to control reactive power for maintaining all bus voltages. Thus, Secondary Voltage Regulation was designed. It divides power systems into some control areas and controls pilot node with the included generators. The reactive powers of generators can control pilot bus voltage continuously and fast. Therefore we need to divide areas and select control generators for SVR with Electrical distance. Then estimation of the reactive power reserves of geneators is needed in voltage control areas to control voltages of the pilot nodes.
