Challenges of Grid Integration of Wind Power on Power System Grid Integrity: A Review

Wind Energy Conversion Systems (WECSs) exhibit variability in their output power as a result of change in their prime movers (wind speed).This introduces a new factor of uncertainty on the grid and poses a lot of challenges to the power system planners and the utility operators in terms of the power system grid integrity i.e. power system security, power system stability and power quality. This paper discusses the various challenges of wind power when integrated into the grid and identifies different mitigating strategies for its smooth integration. This paper therefore enables the specifications for mitigation/integration technologies to be appreciated and quantified.
