Distributed energy resourcesProject Advanced Planning of PV-Rich Distribution Networks Study
This report presents a cost comparison among potential solutions that can be used by DNSPs to increase residential PV hosting capacity.
This report presents the work and findings corresponding to Task 5 “Cost Comparisons Among Potential Solutions” part of the project Advanced Planning of PV-Rich Distribution Networks with funding assistance by the Australian Renewable Energy Agency (ARENA) as part of ARENA’s Advancing Renewables Program and led by the University of Melbourne in collaboration with AusNet Services. It focuses on the cost comparison among potential that can be used by Distribution Network Service Providers (DNSPs) to increase residential PV hosting capacity in distribution networks.
Chapter 2 of this document presents the traditional (investigated in Task 3 “Traditional Solutions” and non-traditional solutions (investigated in Task 4 “Non-Traditional Solutions” which later are combined to form complete solutions. To enable the comparison of costs, the complete solutions are selected based on their ability to mitigate both voltage and asset congestion problems to achieve 60% and 100% of PV hosting capacity in each of the four HV feeders (urban and rural) fully modelled in this project. Chapter 3 presents the data and considerations used for cost comparison among complete solutions to increase PV hosting capacity. Chapter 4 briefly describes the data and considerations used for the analysis that forms the power flow groundwork done in Task 3 and Task 4. Chapters 5 to 8 present and discuss the results obtained for each of the four HV feeders. Finally, conclusions and next steps are presented in Chapters 9 and 10, respectively.
