Dynamic stability is a major concern in maintaining the security of power grids with high shares of power electronics-based resources. Stability analysis tools are needed to evaluate the impacts of power electronics converters on system stability at slow and fast time scales. This project will investigate a new impedance scan method, which provides a more accurate impedance representation to investigate stability challenges associated with power electronics connections. If the project is successful, it will enable power engineers to do similar studies in the future and obtain a more accurate impedance representation.
Benefits
The net benefits for consumers from this project is expected to be delivered collectively from lower cost and risk for power electronic based devices connections, i.e. wind farm, solar farm and HVDC connections.
The outputs of this research will support energy networks building more understanding on interaction and instability issues associated with power electronics converters. It will allow the better planning for integration of power electronic devices. It will also help us in taking mitigating actions to avoid unplanned outages resulting from interaction issues.
