Building a microgrid laboratory

Microgrids are local area power systems, and are attracting increased attention due to their potential to provide a solution to integrate renewable energy into the wider grid. In order to facilitate experimental research, a microgrid laboratory has been built by CSIRO in Australia. Experiments have been carried out which investigate issues of integrating distributed generation, including renewable energy, into the electricity network. This paper describes some of the challenges involved in setting up such a facility and provides examples of experimental results. This facility is unique in its incorporation of three types of solar PV technologies, two types of wind power, three types of battery storage, and a programmable load bank. The availability of a flexible facility such as this is essential in advancing the science in this area, and is leading to valuable insights into microgrid operation.
