摘要：This paper presents a study of the 380-kV network of Saudi Electricity Company in the Western
Operation Area (SEC-WOA). Where, the effect of using series, shunt, and mixed capacitors for
reactive power compensation on the network is investigated. Three different load levels namely
light, medium, and peak have been considered in the investigation. Power world simulator
(PWS) is used to perform the network load flow analysis, the obtained results were identical to
the real load flow in the company documents. PWS based Dynamic Programming is used to
determine the size and optimal location of the capacitor used in each scheme used for reactive
power compensation for the network and compared to the optimum solutions obtained by both
the Genetic Algorithm (GA) and the Hybrid Genetic Algorithm (HGA). The comparison reveals
better solutions of the proposed method compared with GA and HGA .
