IEEE Distinguished Lecturer Program (DLP) – Impact of high solar PV penetrations on distribution network

Organised by PES Victorian Chapter

Wednesday, 10th July, 6pm-7pm, at The University of Melbourne


Rooftop solar PV penetration in the Australian distribution network has increased exponentially over the last five years. This is also evident in many other countries. Total installed PV capacity has now exceeded wind generation capacity in Australia. This has been possible due to feed-in-tariff and other government subsidies along with customer’s awareness of environmental sustainability and increased electricity price. This brings some challenges for the utilities and customers, which include bidirectional power flow, less inertial generation and unregulated/intermittent behaviours. Most PV systems are integrated at a power distribution level, and distribution networks have never been balanced due to asymmetrical upstream sources, non-transposed lines and uneven phase loads, thus analysis of PV integration impacts should take network imbalance into account. In steady states, unbalanced loads and PV power have unequal contributions to voltage drops of each phase. Moreover, during cloud coverage phases of unbalanced networks have different voltage variation sensitivities to PV power swings. Therefore, it is possible that an unbalanced network may suffer over voltage and unacceptable voltage imbalance at certain buses. These voltage problems are exacerbated with increase in PV penetration levels, which may have to be confronted in the near future. Even for low PV penetration, some power utilities have already experienced similar voltage issues and started to reject further grid-connected PV applications. This seminar will highlight these voltage problems of PV integration into an unbalanced distribution network. University of Queensland has been in the forefront of solar PV integration research. University has 4.5 MW solar PV plants in two campuses. This presentation will highlight some key research outcomes in this area.

Biography of the presenter:

Prof Tapan Saha was born in Bangladesh and immigrated to Australia in 1989. Tapan received his PhD from the University of Queensland in 1994. Previously, Tapan obtained a B. SC in Electrical & Electronic Engineering from Bangladesh University of Engineering and Technology (BUET), Dhaka in 1982 and a Master of Technology in Electrical Engineering from Indian Institute of Technology, New Delhi in 1985. He has been with the University of Queensland since 1996, where he has been a Professor of Electrical Engineering since 2005. Currently he is an Adjunct Professor of Xi’an Jiaotong University and Hunan University in China. Previously he worked in James Cook University of North Queensland, Townsville for two and a half years and in BUET for three and a half years. 

Tapan Saha is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE) and the Institution of Engineers Australia. He is a Chartered Professional Engineer (CPEng) of Engineers Australia and a Registered Professional Engineer of the State of Queensland (RPEQ). He is on the National Engineering Register (NER). Prof Saha is on the APEC Engineer Register and on the Register of International Professional Engineers.
