Abstract: A method for controlling an energy conversion system (20) is provided. The system comprises a rotating electrical machine (22), a machine-side converter (24), a DC-link (26) and a grid-side converter (28). The method comprises modulating the machine-side converter (24) for converting an AC voltage of the rotating electrical machine (22) into a DC voltage supplied to the DC-link (26); and modulating the grid-side converter (28) to convert a DC-link voltage at the DC-link (26) into an AC output voltage to be supplied to an electrical grid, wherein the machine-side converter (24) is modulated with first optimized pulse patterns, which have been optimized such that a peak value of the DC-link voltage or of a DC-link voltage component of the DC-link voltage is constrained to a predetermined value.

Abstract: A method for controlling a modular converter (16) connected to an electrical grid (12) for active power filtering the electrical grid (12) to compensate for a load (14) connected to the electrical grid (12), comprises: receiving an actual load current (i i ) and an actual converter state (x) of the modular converter (16); determining, from the actual load current and a history of previous load currents, a sequence of future load currents over a prediction horizon (40); predicting a sequence of future converter states of the modular converter (16) and a sequence of manipulated variables (U) for the modular converter (16) over the prediction horizon (40) by solving an optimization problem based on the actual converter state (x) and the future load currents by minimizing an objective function mapping control objectives to a scalar performance index subject to the dynamical evolution of a prediction model of the modular converter (16) and subject to constraints (42); and applying a next switching state, which is determined from a first element of the sequence of manipulated variables (U), to the modular converter (16).
