New iGrid reports:

  •     You can view all the final Intelligent Grid Cluster Reports from the new look Resources and Publications section.
  •  You can download a copy of the  Australian Decentralised Energy Roadmap which was launched today by Honourable Martin Ferguson, Minister for Resources and Energy; Minister for Tourism.  The event will take place in Sydney on the 15 December,to the launch of the report developed by the University of Technology, Sydney.  The Roadmap is intended to provide a concise and practical blueprint for accelerating the deployment of distributed energy in the form of energy efficiency, load management, distributed generation and smart metering in Australia.  Click here to download the Roadmap

Micro-Grid

Full Name
Operation control and energy management of grid-connected distributed generation based on a “micro grid”.

Project description
This project focuses on the management of electricity using a systems approach, in which generation and associated loads operate as a subsystem or “micro-grid”.

The initial aim will be to develop automatic shedding and restoration schemes within a micro grid and to operate the generators to optimise electrical performance. The project will develop hardware for load control down to emergency levels and to have coordinated controllers for turbines and inverters. The first task will be to probe the limits of the control possible without an explicit communications network to loads or generators. The next phase will be to determine the improvement in power quality and control using only broadcast from a single node, typically the reconnection breaker. This will build upon existing studies by QUT researchers.

Methodologies to define develop and demonstrate control strategies that will ensure the most efficient, reliable and economic operation and management of the micro grid.

To define appropriate protection and grounding policies that will assure safety of operation and capability of fault detection, isolation and islanded operation.

A determination of switching control strategies of DG supplied inverters for operation in voltage, current and power control mode.
Construction of a distributed generation-based micro grid with protecting devices including solid state breakers to maximise safety and circuit protection.

Expected Outcomes
A report on the main issues regarding the operation of the micro grid in parallel with the mains and in islanding conditions that may follow faults.

A report on control strategies that will ensure the most efficient, reliable and economic operation and management of the micro grid.

A report on appropriate protection and grounding policies that will assure safety of operation and capability of fault detection, isolation and islanded operation.

A report switching control strategies of distributed generation supplied inverters for operation in voltage, current and power control mode.

A report on the parallel operation of multiple distributed generation sources with the utility supply their stability and harmonic aspects.
