Electrical energy is the most widely used form of energy worldwide. The world is currently experiencing severe energy shortages as the fossil-fuel deposits are decreasing at an alarming rate. The increased awareness about environmental hazards, caused by the burning of fuels, is also forcing governments towards exploiting renewable-energy resources. Wind is one the important renewable resources, abundantly available, and offers the lowest cost per MWh as compared to most other renewable-energy resources. Harvesting energy from the wind as an alternative to fossil fuels has many advantages in terms of protecting the environment and promoting sustainability. However, voltage profile of distribution networks with interconnected Wind Power Plant (WPP) can be significantly affected ascribable to the limited capability of Wind Turbine Generators (WTGs) in regulating terminal voltage through reactive power control.
