Voltage regulation of electric power network interconnected with wind energy distributed generations

The large scale connection of power generation in distribution networks causes deregulation in power system networks. This paper focuses on studying the voltage changes at each node of the distribution network before and after the insertion of wind turbines as power generators, and also proposes two optimal voltage control methods in order to maintain a stable voltage profile. Results of the simulations are presented in order to confirm the proposed ideas and assert the effectiveness of the used regulators as well as their optimal capacity control.
