Load-Frequency Control in a Two-Area Power System Using the Fuzzy-PID Method

Power systems are plant units connected to each other, with the electrical power flow constantly moving between them and load. All must be implemented in such a way that they remain stable not only under normal conditions but also after implementation of unwanted inputs or malfunctions should able return nominal as soon possible. The basic factors stability control system frequency different areas amount them. Now main goals have been stated, these indicators kept at their desired levels through design controllers. This paper first describes mechanism load (LFC). parameters several types complementary controllers then designed based on proposed algorithm. simulated finally applied, effect controller faster damping fluctuations is discussed. In this study, multi-area disturbance area performance controlling whole network investigated. case studies show share active reactive generation sources region greatest impact control, given coefficients determined using fuzzy logic shortest possible time number transient oscillations eliminated, resulting steady system.
