Over-frequency support in large-scale photovoltaic power plants using non-conventional control architectures

•Photovoltaic power plants must provide grid services defined in the grid codes.•There is a trend to reduce the frequency regulation response time requirements.•Common centralized control solutions have limitations to reach a fast response time.•The proposed hierarchical control architecture achieve...
