Economic dispatch of power system incorporating wind power plant

As wind power penetrations increase in current power systems, its impacts to conventional thermal unit should be investigated. 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, genetic algorithm (GA) 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. Ten units system incorporating one wind power plant is utilized for numerical simulation. Different simulations scenarios with and without wind power production are simulated. Simulation result shows the effect of wind power generation in reducing total fuel cost.
