Power and energy systems

Some of our recent projects:

Energy policy case study

In 2017, the Melbourne Energy Institute was engaged by the Finkel Review to perform security assessment studies for future energy scenarios of the Australian National Electricity Market (NEM). The outcomes of the research work, led by Professor Mancarella, were published in the report Power System Security Assessment of the Future National Electricity Markets. The report discussed fundamental principles of secure operation of low-inertia power systems and demonstrated the use of frequency response security constrained optimal power flow tools and their potential application to energy markets in a system dominated by renewable energy sources and low-carbon technologies that are asynchronously connected to the system.

Solar PV impacts in Australian HV and LV networks

A collaboration with AusNet Services

In 2016, collaborations started with the Australian Distribution Network Service Provider, AusNet Services, looking at the impacts of widespread residential solar PV as well as potential solutions. To date, Professor Ochoa has led the projects “HV-LV Analysis of Mini Grids Clusters” and “Solar PV Penetration and HV-LV Network Impacts”. These projects have already produced key insights on the requirements for detailed HV and LV network studies.

Solutions for increasing PV hosting capacity

A collaboration with Electric Power Research Institute (EPRI, USA)

In 2018, led by Professor Ochoa, collaborations started with the Electric Power Research Institute (EPRI, USA) to help EPRI develop advanced distribution planning tools that can assess the performance of different PV-based integration solutions. The project “Assessment of Integration Solution Methods for Increasing PV Hosting Capacity” will help distribution network operators to quickly determine the most cost-effective, integration solutions for high penetrations of medium-scale PV systems across large network areas and, hence, increase the corresponding hosting capacity.

Port Lincoln Virtual Power Plant

Professor Mancarella has been engaged by Hydrogen Utility (H2U) to carry out techno-economic modelling and demonstrate the technical and economic feasibility of the first hydrogen-based multi-commodity virtual power plant at Port Lincoln in South Australia. The project takes place in a network-constrained area with high potential penetration of solar and wind energy resources whereby electrolyzers will be used to produce hydrogen and ammonia for multiple purposes, including active network management, energy storage, export of zero-carbon fuels, supply of zero-carbon refuelling stations, fast frequency response, and frequency control and system restart ancillary services.
