N2 - Integration of solar photovoltaic (PV) power plants onto the electric utility grid can pose some challenges from the perspective of operating the power system (balancing load and demand) and in interconnecting a PV power plant (controlling distribution system voltage variations and thus power quality). An issue of particular importance is the rate at which the solar irradiance changes, and the consequent rate at which the power output changes, i.e. the ramp rates. Pertinent information describing the ramps is the frequency, duration, and magnitude of the ramps. This paper compares different methods of computing ramp rates in both irradiance and power. The "dead band" method, an historical data compression technique, is demonstrated for identifying fluctuations in the one second to several second timeframe. Ramp calculation methods are presented along with the results describing ramp events for two case studies.
