  The economic dispatch of wind power units is quite different from that in
conventional thermal units, since the adopted model should take into
consideration the intermittency nature of wind speed as well. Therefore, this
paper uses a model that takes into account the aforementioned consideration in
addition to whether the utility owns wind turbines or not. The economic
dispatch is solved by using one of the modern optimization algorithms: the
particle swarm optimization algorithm. A 6-bus system is used and it includes
wind-powered generators besides to thermal generators. The thorough analysis of
the results is also provided.
