Optimal capacitor plac ement in a distribution s ystem using ETAP sof tware (Badri. A. Bakar) 0.90 power factor. It ca n be noted from Table 1 that branches are having 469.7kW and 1248.4kVar loss and branches ha ving maximum voltage drop of 10.23 percent. Before capacitor placement minimum voltage is
The objective function of the capacitor optimal placement in distribution networks is the cost of installed capacitors, installation costs, etc., and the cost of power and energy losses.
Decreasing the total network loss is often the main reason for using capacitors in distribution networks. Capacitor placement approach involves the identification of location for capacitor placement and the size of the capacitor to be installed at the identified location.
The buses that are located at the top of LSIs list are considered the candidate buses for the capacitors placement, while the buses have the less sensitivity to the installation of capacitors are indexed at the bottom of this list. Table 2. Ranking of load buses based on LSIs for 34-bus distribution system Table 3.
Simulations were implemented in two standard 10 and 33-bus systems. The results showed that there is a voltage drop problem at the end of the system in the 10-bus system, and this voltage drop can be improved by capacitor placement. In addition, network losses can be reduced.
In addition to reducing power and energy losses in load peak, optimal capacitor placement can free up distribution equipment capacity and improve the voltage profile. Hence, over the past decades, the optimal capacitor placement has been widely studied.
