Abstract: A converter arrangement (1) and a method of controlling a three-phase converter arrangement connected to a transmission grid is provided. The converter arrangement (1) comprises three phase legs (10, 20, 30) and an energy transfer circuit (40). The method comprises providing a varying respective output phase (A, B, C) voltage to the transmission grid by selecting (206) energy storage elements (12A-n, 21A-n, 31A-n, 44) of both the phase legs (10, 20, 30) and the energy transfer circuit (40) and connecting (210) the selected energy storage elements (12A-n, 21A-n, 31A-n, 44) to the transmission grid output (15, 25, 35). The method further comprises selecting (208) energy storage elements (12A-n, 21A-n, 31A-n, 44) for performing a transfer of energy between the energy storage elements (12A-n, 21A-n, 31A-n, 44) during the control period.

Abstract: Since a conventional electric vehicle charging station (EVCS) can dramatically influence a power grid performance without proper control, it is desirable to provide a control system for an EVCS that can enhance stability of power grid operation. The present invention provides a control system that receives, from a power grid, an ancillary order defining the amount of electric power transmitted from the EVCS to the power grid or from the power grid to the EVCS. A central controller distributes the ancillary service order to local controllers periodically. The local controllers control, in real time, electric vehicle supply devices based on the distributed ancillary order and provide an ancillary service for the power grid that corresponds to the distributed ancillary service order.
