Power flow control in a substation of a wind- and solar farm: Design of an Optimisation Unit Considering a System's Physical Boundaries and Technical Constraints

The goal of this graduation project was to design a state-of-the-art central farm controller. The designed central farm controller distinguishes itself from prevailing controllers by including a subsystem (the optimisation unit) that contributes to an improvement in power transmission effciency, decrease in maintenance costs and an increase in...

Real-time Active- and Reactive Power Control in a Combined Wind- Solar PPM

Increase in wind- and solar parks complicate grid stability due to their deterministic behaviour. ENTSO-E established requirements for generators for grid connection in Europe. A requirement is to have active- and reactive power control that implements a power setpoint given by the transmission system operator. This thesis describes the design...
