Abstract : The voltage stability problem has gained the position of a vital issue to be addressed by the electrical power industry worldwide. In fact, many of some serious and major system break downs occurred in different power systems resulting in partial or total blackouts, are understood to have been due to voltage instability. The reactive power management under different operating conditions, different load behaviors, and different seasonal variations requires long-range planning rather than ready-made solutions based on peculiarity of a specific power system. The Kingdom of Saudi Arabia has its own peculiar features not only in regard to its consumer loads but also in regard to the site-specific generation locations. The predominant load here is the air-conditioning. The water availability, the fuel availability and the environmental hazards of thermal generation forced the generation locations to be away from the population centers. The growing reactive power (MVAR) demand as a vital supplement of the active power demand of the load centers, if pumped through long transmission overhead lines from distant generating sources, would result into severe voltage drop at the receiving end. Therefore, the reactive power demand of a load center has to be met from somewhere nearest to or within the load center. The stalling phenomena of induction motors of air-conditioning under post fault dynamic conditions demand additional reactive power margins of MVARs to be available close to the load centers to inject the reactive power deficit instantly to overcome motor stalling that lead voltage delayed recovery problem. Accordingly, this thesis aims to determine the required MVAR to solve such phenomenon for Saudi system in year 2017 considering the following procedure: 1. Base Case and Model Development 2. Determine the Weak Point in the System 3. Establish Dynamic Reactive Compensation requirements Using Air-Conditioning Load Model 4. Overall Optimization of Reactive Compensation Requirements
