This combo session starts with the Dynamic Performance of Wind Generation WG Meeting and be followed by the proposed panel session. Both events must be scheduled for the same room. The first hour will be dedicated to the WG meeting. Following the WG meeting a panel session will be held cover- ing the latest results and experience with plant level model validation work using field measured data, such as from phasor measurement units at the point of common coupling of the wind or photovoltaic plant, studies performed using the latest 2nd generation generic models for wind and photovoltaic tech- nologies and experience with modeling and performance of plant level controls. This is an ideal forum for planners, system operators and researchers interested and working in the arena of renewable energy systems to come together and discuss the latest developments in the modeling and model validation of these technologies.
