Explicit model predictive control with disturbance observer is discussed for grid-connected voltage source power converters. Control objectives are set-point tracking of the DC-link voltage and reference tracking of the reactive power exchanged with the grid under unknown disturbances (load power). Controller and observer design are based on a linearized(More)
We discuss observer and state-feedback controller design for grid-connected voltage source power converters with LCL-filter under symmetric grid voltage variations where only the converter-side currents are available for feedback. The LCL-filter is modeled as lossy network including resistances, capacitance and converter-side and grid-side inductance.(More)
We discuss pole-placement based nonlinear state-feedback control of the DC-link voltage in grid-connected voltage source power converters. For controller design we use a linearized system model, compute the feedback gains via pole placement and present an analytical expression for the gains in dependence of the actual operating point. The linearized model(More)
Abut twenty years ago, the European Commission established the BCR (Bureau Communautaire de Référence) programme with the objective of improving the quality of the results of measurements, in order to assist in the establishment of reliable and comparable measurement systems in the EU member states. Its usual procedure consists of collaborative(More)
This chapter provides an introduction to the modeling and control of power generation from wind turbine systems. In modeling, the focus is on the electrical components: electrical machine (e.g. permanent-magnet synchronous generators), back-to-back converter (consisting of machine-side and grid-side converter sharing a common DC-link), mains filters and(More)
