Oman vision 2040 aims to expand investments, industrial projects and attract more capital. The complexity and the demand for electricity in the Oman grid are already increasing day by day due to existing development in the country. This evolution will cause an unexpected increase in power demand and consequences on Distribution and transmission lines. Constructing a new generation plant, redesigning the infrastructure, installing solar farms, and building new parallel transmission lines become unavoidable to meet the higher power demand and to eliminate voltage problems. This paper describes in a method that can meet the demand of reactive power compensation to improve the power flow. A flexible AC transmission system (FACTS) is a known technique that consists of electronics to deal with the power flow control of an existing distribution system through power semiconductors. This paper focuses to show the effect of Static Var Compensator (SVC), which is used to improve the voltage profile in the distribution system. A case study of the 33 KV distribution network in Tiwi city in Sharqiyah southern region of Oman is modeled using ETAP software. Simulations have been done to analyze and represent the results to prove the effectiveness of SVC for compensating the voltage drop. The voltage drop issue in the system has been resolved after installing SVC on the Tiwi bus. The voltage drop without SVC is above the tolerance limit of 6.2 %, which turns on the alert for the under-voltage. Moreover, the system power losses are 0.346 MW. However, after installing the SVC, the voltage drop decreased to 3.39 %, which is better than the conventional solutions. Also, the system power losses decreased to 0.32 MW. Financial studies have also been shown to determine cost efficiency of the solution.
