Abstract: Electrical power is transmitted at high voltages to reduce the transmission losses and increase the transmission efficiency. Studies reveal that transmission and distribution(T&D) losses are around 33% of total power generated which is causing huge revenue loss to the electrical utility companies. In order to make profit the utilities has to reduce the T&D losses to 22%. Reactive currents account for a portion of losses. The losses produced by reactive currents can be reduced by the installation of shunt capacitors in the distribution system. A proper placement of fixed and switched shunt capacitors reduces energy and peak power losses, release additional KVA capacity from distribution apparatus and improve the system voltage profile. In this work optimal capacitor placement in a 34-bus system is achieved by using fuzzy expert system. Capacitor banks are placed on the nodes with highest suitability.
