ABSTRACT

SALMIAH. Reactive Power Feed Optimization using Linear Programming Method, a Case Study of South Sulawesi Electrical Power System (supervised by Nadjamuddin Harun and A. Toyib Rahardjo).

The objective of this study is to use linear programming method of optimization in determining the locations of reactive power compensators in South Sulawesi Electrical Power System through a fast-decoupled load flow analysis. The study includes the implementation of the method in 3 (three) different cases of voltage profiles.

In case I and case II, the method has successfully increased the voltages at bus 6 and 7 from their lowest values of 0.820 p.u and 0.827 p.u. respectively to values above 0.9 p.u as required for a standard operation. In case III, however, the voltages at bus 6 and 7 are still below 0.9 p.u. even though the minimum voltage has been increased up to 0.96 p.u. Bus 6 turns to be the most sensitive bus to the reactive power compensation.
