The Australian Federal Government and the Australian Renewable Energy Agency (ARENA) have awarded almost half a million dollars in additional funding to the Monash Energy Institute to further investigate the integration of renewables into the national energy grid.
The groundbreaking two-year project has now been awarded investment to a total of $1.3m.
According to ARENA CEO Darren Miller, “Monash’s study will aim to provide a solution for other renewable energy zones across Australia and help increase the value delivered by renewable energy, reduce or remove barriers to renewables uptake and help to increase the overall skills, capacity and knowledge about the relevant technologies”.
The Monash Energy Institute said that study will explore a variety of techniques to mitigate grid stability issues which will include the siting and operations of technology such as synchronous condensers, wind and solar farms, and battery systems incorporating advanced inverter systems.
Dr Tony Marxsen, Chairman of the Monash Energy Institute’s Grid Innovation Hub will co-lead the project alongside Dr Behrooz Bahrani, Director of the Grid Innovation Hub.
According to Dr Marxsen, the goal of the project is to streamline stable connections of large renewable energy facilities to remote areas of the grid.
“Australia’s national grid has its strongest links between major cities and the nearest traditional sources of energy, typically coalfields,” said Dr Marxsen.
This will enable a smoother transition to renewables, especially for solar and wind energy producers who can experience local grid weakness if they are located in remote areas.
“Our countries renewable energy future will use decentralised energy sources in areas of high winds and lots of sunshine - and these areas tend to be more remote from cities, where the grid is weak”.
Initial stages of the project will use the West Murray Region in north-west Victoria, which includes five solar farms as a primary case study.
According to Dr Bahrani, the West Murray region was the perfect candidate for the project as it has experienced an array of problems with renewable connectivity.
He expects that these problems will continue if a viable solution is not found soon.
“As each renewable project applies for connection to the grid, it is subject to a detailed engineering analysis to ensure it won’t create problems that might affect grid stability and security,” said Dr Bahrani.
Some of the technical issues that may affect renewable generation operation and connection to the grid in NSW and Victoria include converted instability, low short circuit levels and thermal limitations.
Dr Bahrani says that “This project should provide insights and possibly even pre-engineered solutions to ease this burden and speed up connection approvals”.
It is hoped that the findings will help Australia transition to a national energy grid that will include significantly more renewables.
The Australian Energy Market Operator (AEMO) Managing Director and CEO, Audrey Zibelman said that “Australia has the technical capacity to operate our power system with solar and wind generation contributing up to 75 per cent of our energy at times”.
The project will commence in July 2020.
