RECENT ADVANCEMENTS ON POWER SYSTEM RESTORATION

Traditional and current restoration strategies use top down approach that rely on the use of centralised conventional generation such as hydropower plants and gas power plants to start up the network after a wide area blackout. Analysis of restoration steps is also based on AC networks with no involvement of DC schemes. The distribution network has also been assumed to be passive having to wait for the transmission scheme to be stable. Today and future restoration strategies should align with the changing network paradigm. Prediction of high penetration of renewable resources coupled with increasing DC schemes demands change in restoration strategies. A review of role of Wind Power Plants, HVDC, BESS, SST and WAMS in the restoration process is presented in this paper.
