Certain investigations on radial Distribution system optimization With capacitor and facts devices Through hybrid heuristic technique

Abstract

Power distribution networks are built as interconnected systems newlineThey are constructed by one of the three types radial loop and network newlineSystem They are usually arranged to be radial in operation to simplify overcurrent newlineProtection In general distribution systems are designed to be most newlineefficient at peak load demand Utilities are constantly looking for newer newlinetechnologies that enhance power delivery performance Amongst all control newlineof power loss and balancing the unbalanced loading at the feeder phases refer newlineto phase balancing and these are the two most important issues which newlinedetermine the power delivery performance of the distribution system The newlineincrease in power loss and unbalanced loading at the feeder increase energy newlineloss risk of exceeding their branch currents and bus voltages capacity newlinedeteriorate power quality and also increase electricity cost To deal with this newlineproblem several strategies are employed to minimize power loss and phase newlinebalancing at the feeder such as inclusion of capacitor banks phase swapping newlineand system and or feeder level reconfiguration newlineNetwork reconfiguration is the process of changing the topology of newlinedistribution systems by altering the open close status of switches newline
