Reactive Power Optimization problem has significant influence on secure and economic operation of power system. In this Book Bio - inspired Algorithms (AGA, SEPSO, ARPSO, and ACSA) has been applied to solve Reactive power optimization problem. And the proposed algorithms has been evaluated in standard IEEE, 30-bus system, 57-bus system & practical 191 utility (Indian) system. Secondly ACSA has been applied for unit commitment problem & tested in 10 unit's model power system. Thirdly ACSA has been... Mehr
