|Abstract:||The continuing increase in demand for electric power has resulted in operation closer to the limit of stability with inadequate voltage profile and unacceptable total active losses. Flexible Alternative Current Transmission Systems (FACTS) devices can provide the possibility to enhance Static Voltage Stability based on Reactive Power Planning (RPP). In this paper, The Static Var Compensator SVC which is considered as a control device together with generators and transformers are used for increasing Loading Margin (LM) referred to Voltage Stability Index (VSI) L-index of load buses, minimization of active total losses and to improve voltage profile described by minimization of voltage deviations. Each problem is treated through the best locations of different SVC equipments at the Stability Margin. This assumption is based on the optimization problem by Genetic Algorithms (GA) for one objective function and Non-dominated Sorting Genetic Algorithm-II (NSGA-II) for two objectives mentioned above. The Algorithm is applied on IEEE 30 Bus test system.|
