The future energy mix will incorporate renewable sources like hydro, wind, solar, and tidal energy, necessitating adaptation of the electricity grid to efficiently use these sources. Renewable power generation units must be modified to ensure reliable electricity supply. To maintain efficient transmission and distribution, reactive power balance must be controlled, as inefficient management can lead to high network losses, equipment overloading, voltage instability, and outages. ABB offers reactive power compensation products and customized solutions, such as the PCS 6000 STATCOM, which is proving reliable and efficient for wind farms in the UK.
