This paper discusses an Evolutionary Programming Approach to obtain optimal wind and thermal generation dispatch. As wind power penetrations increase in current power systems, its impact to conventional thermal unit should be investigated due to the intermittency and unpredictability of wind power generation. Development of better wind thermal coordination economic dispatch is necessary to determine the optimal dispatch scheme that can integrate wind power reliably and efficiently. In this paper Evolutionary Programming (EP) is utilized to coordinate the wind and thermal generation dispatch and to minimize the total production cost in the economic dispatch considering wind power generation and valve effect of thermal units. Different test system incorporating one wind power plant is utilized for numerical simulation. Different simulations with and without wind power production are simulated. Simulation result shows the effect of wind power generation in reducing total fuel cost.
