Automatic load frequency control of multi area power systems

摘要: Variations in load bring about drifts frequency and voltage which turn leads to generation loss owing the line tripping also blackouts. These might be reduced smallest possible value by automatic control (AGC) constitutes of two sections viz (LFC) along with regulation (AVR). Here simulation evaluation is done know working LFC building models SIMULINK helps us comprehend principle behind including challenges. The three area system being taken into consideration together single addition systems. Several important parameters ALFC like integral controller gains (KIi), for governor speed (Ri) as well bias (Bi) are optimized using an optimization technique that Bacteria Foraging Optimization Algorithm (BFOA) because general hit trial method has some demerits insisted on BFOA obtaining desired values different parameters. Simultaneous certain KIi, Ri Bi been grants not only best dynamic response but permits use quiet larger than put practice. This will help industries concerning power simpler cheaper realization governor. performance investigated through convergence characteristics reveal relatively faster such there drop computational minimum computer resource utilization
