Description
Summary:An effective coordination in an interconnected system can be obtained by ensuring proper settings of overcurrent relays. In this research work, the problem of coordinating the overcurrent relays is formulated as a non-linear problem, taking into account the as discrete nature of time dial settings and the pickup current settings. An effective approach based on adaptive differential evolution (ADE) algorithm is proposed to solve the coordination problem. The results obtained by ADE are compared with different algorithms on different model test systems and found to be feasible, robust and efficient.
