Renewables: wind farms and grid support functions

Renewable energy is increasingly a challenge to maintain grid stability. Therefore power stations are often required to provide adaptable grid-supporting functions in the form of so-called “grid codes” or feed-in regulations. This case study describes the situation in Portugal, the need to adapt to Portaria 596 grid code and how the reactive current converters of Knorr-Bremse PowerTech deliver…
