Spontaneous Genesis Control Of Unified Power System By Fuzzy Logic Access

Abstract

Power systems are used to convert natural energy into electric power. To optimize the performance of electrical equipment, it is important to ensure the quality of the electric power. It is well known that three-phase alternating current (AC) is generally used to transport the electricity. During the transportation, both the active power balance and the reactive power balance must be maintained between generating and utilizing the AC power. Those two balances correspond to two equilibrium points: frequency and voltage. The control problem of the frequency and voltage can be decoupled. The frequency is highly dependent on the active power while the voltage is highly dependent on the reactive power. Thus the control issue in power systems can be decoupled into two independent problems. One is about the active power and frequency control while the other is about the reactive power and voltage control. The active power and frequency control is referred to as load frequency control (LFC) [1]. The analysis and design of spontaneous genesis control (SGC) system of individual generator eventually controlling large interconnections between different control areas plays a vital role in automation of power system.
