When a larger quantity of variable renewables is connected to the grids, it could put the stability of the power system in risk. Active power control systems, reactive power compensation devices and LVRT capabilities are among the requirements suggested. The draft standards are seen by the industry as stringent, and would require developers and turbine suppliers to upgrade their equipment (BNEF, 2010b). Industry insiders predict that the new standards could favour a few large wind power manufacturers and drive out smaller competitors.
