Optimal Capacitor Placement to Maximize Voltage Profile in Radial Distribution System

This paper undertakes the problem of loss reduction in a radial distribution System. The objective is to determine the suitable size and location of the capacitors to be placed on a radial distribution system. The objective function is to increase of saving due to reduction of energy losses thereby taking into consideration cost of capacitor. In this part, load flow solution for the radial feeder is obtained and followed by a loss sensitivity analysis to select the candidate capacitor installation in load areas. It obtains the optimal value of capacitors to be installed. The solution algorithms have been developed into and tested on a 34-bus radial distribution system. In the capacitor placement issues, those day to day capacitor operating constraints, load profiles, feeder capacities and allowable voltage limits at light load and peak load levels are all considered while the investment cost and energy loss are minimized. In the proposed method, objective functions and obstacles are represented as antigens. In this part, load flow solution for the radial feeder is gathered and followed by a loss sensitivity analytical statistics to select the candidate capacitor installation in light and high load areas.
