The wind power penetration
levels in the networks could be high, for example, average
wind power penetration levels of 20-30 % with peak
penetration level up to 100%. Which will effectively reduce
the requirement on the fossil fuel based conventional power
generation, however, it also presents many challenges to
modern power systems. The issues, such as power system
operation and control, system stability and power quality,
need to be addressed in order to realise good security and
power quality for the power systems integrating large scale
