Effective subsidy and incentive need to be established to encourage integration of wind power so that the wind power can serve as a substitute energy source and eventually become the main power source. ■ Prediction and control technology is necessary to integrate high penetration of renewables into the grid ■Wind power AGC, AVC & PV AGC, AVC ■Flexible generation plays an essential roll Gas Turbine, Hydro, Pumped Hydro ■Faster dispatch ■Current grid dispatching management model needs to be adjusted to accommodate renewable Coordination of various power resources needs economic and regulatory policies ■ Electricity market, Ancillary services market, Quota system, Assessment indicators of energy consumption per kilowatt for local government#18Your comments and suggestions are welcomed!
