Transient stability constrained optimal power flow solution of ac-dc systems using genetic algorithm

Optimal power flow (OPF) is one of the known problems of the power systems. Many numerical and heuristic methods were used to solve this problem so far. As seen from these studies in literature, heuristic methods are more effective and faster than numerical methods. This case is to make more attractive and mandatory the using of heuristic methods in optimal power flow solution of High Voltage Direct Current (HVDC) systems. In this study, transient stability constrained optimal power flow solution of alternating current-direct current (AC-DC) systems is accomplished by using the genetic algorithm (GA) that is one of the heuristic methods for the first time. The proposed approach is tested on modified New England 39-bus test system.
