Methodology for Extreme power thresholds of photovoltaic power plants

Photovoltaic power plants are significant for their dependence on weather conditions. The consequences include their stochastic change to the production power that has adverse impact on electric power distribution grids. The aim of this survey is to assess the impact of photovoltaic power plants operation on the daily load diagram with respect to output change difference of active power. Statistical methods have been employed to process a methodology based on real-time data measuring both on-site photovoltaic power plant operation and on-site electric power line output from the substation, where the power plant is connected. Both data are measured by synchronous means.
