This report presents the results of system strength PSCAD modelling and challenges encountered that led to mutual termination of the project.
Report extract
The West Murray Zone due to being a high renewable resources area has an influx of renewable inverter-based power electronics generators connecting to the grid. Since the West Murray Zone is located further away from traditional based Synchronous generators and is coupled with increased Asynchronous renewable generator connections, this has reduced the available fault level in the area which in turn has negative impact on the Network power system security.
