Dynamic Simulation of Power Systems with Grid Connected Windfarms

Wind energy development is consumer and environment friendly, it requires shorter construction time compared to thermal, nuclear generation and is cost competitive. It becomes one of the most competitive sources of renewable energy. However, wind power has some disadvantages. For example, wind power is considered an intermittent power supply because wind does not blow 100% of the time. Besides, the superior wind sites are usually located in remote areas; therefore, it may require substantial infrastructure improvement to deliver the windgenerated power to the load center. There are four major types of wind generators, which are used very widely. (i) Squirrel cage induction generators (ii) Doubly fed induction generators. (iii) Direct driven synchronous generator (iv) Permanent magnet synchronous generator.
