Impact Analysis of PV Penetration on Radial Distribution Feeder of National University of Science and Technology (NUST)

Distributed generation has potential to mitigate the problem of increasing energy demand with no extension of transmission and distribution system. Increased penetration of distributed generation on low voltage feeders has changed the distributed network from passive to active network. This penetration also affects the power quality of the system and poses various problems too, such as the overall system voltage rises above the nominal value and current swings. This paper presents a case study of a 19 bus radial feeder network in NUST Islamabad to analyze the effects of varying distributed generation penetration level on medium voltage feeder voltages using MATLAB Simulink. The maximum amount of distributed generation penetration that is feasible without violating feeder nominal voltage limits is also suggested.
