    This paper proposes a new Smart-Load concept using AC drives. The concept is based on a secondary control layer coordinated with the network and the load to provide active power support. The general Smart-Load concept is developed and synthesized for its practical implementation in network power–frequency support applications. A multi power-frequency droop line is proposed. The final idea is applied to a fan load powered by an AC drive based on an induction motor and a two level voltage source converter. Experimental results show that a full power-frequency response can be achieved by the Smart- Load within 2s of the network frequency deviation.
