Voltage S tability Assessment of Sudan ese National Network within Re Evaluation of the SVC Projects

In the last ten years Sudan National Grid suffering from a steady increase in loads, with shortage of generation and congestion transmission substations lines. This caused many cases blackouts. As solution to this situation, Static Var Compensators (SVC) project was recommended improve voltage (NG) by providing adequate reactive power support at specified nine locations solve instability problems. study re-evaluates project, especially after delay implementation major change that occurred NG evaluation will cover all proposed (Port-Sudan (POR), Hag-Abdallah (HAG), Farooq (FAR), Mahadiya (MHD), Kuku (KUK), Local market (LOM), New Hasahisa (NHAS), Bagair (BAG), Gamueia (GAM).) show its effect on overall voltage.
