Abstract

In this paper Shuffled Frog Leaping Algorithm (SFLA) algorithm is used for optimal DG placement in distribution system. DG placement plays an important role in radial distribution network in filling the demands of consumers. DG is a small generating plant which generates electrical power to minimize the power losses, improving the voltage profile of the network. The locations and sizes are found simultaneously by SFLA algorithm. The main objective is to attain ample improvement in the voltage profile and substantial reduction in network power losses and economic benefit. The main idea behind SFLA algorithm is the interacting virtual population of frogs partitioned into different memeplexes. IEEE 33 bus and 69 bus test systems are used for the analysis and the results were compared with other techniques.
