Control algorithms for primary frequency and voltage support

Report containing a description of the simulation model, laboratory tests, case studies, and recommendations on control functionality which is of maximum benefit for the grid, within the limitations of wind turbine capability. The deliverable is referring to task 4.1.1. Measure of success: Quantified benefit to the grid of the strategies, and successful implementation of the functions in the baseline plant controller as well as successful verification in as well as real laboratory. Participant actions: DNV NL primary frequency response with rotor inertia, SINTEF virtual synchronous machine and reactive power control, laboratory verification DTU provide reactive power control tuning results of Task 4.2.1, VF contribute to development of methods for frequency and voltage support. ORE contribute to development of methods for frequency and voltage support.
