Photovoltaic Based Loading Balance of Distribution Feeders With Loop Power Controllers in Distribution Feeders

Abstract

Balancing load of distribution feeders is significant for falling of power loss and mitigating power flow. As theloop power controller is implanting for the active power and reactive power flows by change in voltage ratio and phase shift.So that the balancing of the load distribution feeders can be achieved. However it can include photovoltaic power producingin feeder balancing load, as a Taipower distribution feeder consisting of two feeders with large amount of photovoltaicequipment considered. The balancing load can be determine in distribution feeders with photovoltaic set up by using the looppower controllers as the changing of solar energy and power loading of feeders.  Daily loading unbalance is set by analyzing PV power generation recorded by the system and by constructing daily power load profiles supported distribution automation system (DAS) data. The load transfer needed to realize loading balance and therefore the line impedance of distribution feeders ar used to derive the voltage, ratio and phase shift of the LPC. Computer simulations indicated that loading balance is achieved in distribution feeders with massive PV system installation by exploitation loop power controllers according to the variation of solar energy and loading of study feeders. The system power loss reduction ensuing from feeder loading balance by LPC is additionally investigated during this paper.
