Genetic Algorithm Based Wind-Thermal Coordination Dispatch Including Transmission Losses

In this paper Genetic Algorithm (GA) is used to solve wind and thermal dispatch problem with non-smooth fuel cost functions. Dispatch of wind and thermal system includes the determination of total cost of generation of all the units in the system which satisfies the load demand including line losses, equality and inequality constraints thereby minimizing the fuel cost. The unit minimum/maximum operational constraints, effects of valve-point loading and line losses are taken into consideration. To validate the results obtained, two test systems consisting of three and six units are considered. Solutions of the systems are obtained including and excluding transmission losses with non-smooth cost functions. Numerical simulation of the coordinated system reduces the total fuel cost.
