Abstract
With increasing penetrations of wind generation, based on power-electronic
converters, power systems are transitioning away from well-understood synchro-
nous generator-based systems, with growing implications for their stability.
Issues of concern will vary with system size, wind penetration level, geographical
distribution and turbine type, network topology, electricity market structure, unit
commitment procedures, and other factors. However, variable-speed wind tur-
bines, both onshore and connected offshore through DC grids, offer many control
opportunities to either replace or enhance existing capabilities. Achieving a com-
plete understanding of future stabil ity issues, and ensuring the effectiveness of
new measures and policies, is an iterative procedure involving portfolio develop-
ment and flexibility assessment, generation cost simulations, loa d flow, and secu-
rity analysis, in addition to the stability analysis itself, while being supported by
field demonstrations and real-world model validation.
