Abstract

Wind unpredictability impacts power stability especially, in high demand areas. Voltage instability is not a new phenomenon for utility providers but the impact is greater with the increase integration of renewable energy systems. The existing 1 MW wind farm consists of an aging fixed speed squirrel cage induction generator (SCIG). The SCIG are known to drain huge amount of reactive power from especially weak utility networks such as the one in Gambia. DIgSILENT Powerfactory was used to analyze the impact of low voltage ride through (LVRT) of 1 MW squirrel-cage induction generator (SCIG) and 1 MW doubly-fed induction generator (DFIG) on the GBA utility network. The results showed a reduction in reactive power absorbed by the generators thereby increasing voltage stability.
