The impact of high PV penetration into the grid particularly at the distrib ution side has b een extensively studied. However, most of the availab le research focuses on North American style systems. This project aims to investigate the effect of high PV penetration at a residential area in a European-based distrib ution network, which is electricity supply system Malaysia is b ased on. The modeling is done using OpenDSS while the network model used is the IEEE European Low Voltage Test Feeder which consists of 55 loads representing a generic housing area. Each load point is then equipped with a 4 kW PV system-representing a typical size for a house installation. PV output variab ility is then introduced into the modeling using two sample days of actual irradiance variab ility ob tained from UTeM Malaysia; one for clear day and another for a high variab ility day. Voltage unb alance, voltage rise and reverse power flow were analyzed. One significant finding of this project is that voltage rise exceeds the standard of 1.05 pu during noon. Besides that, the high variab ility days significantly affect the mitigation measures required to manage reverse power flow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
