Renewable energy resources such as wind, wave, solar, micro hydro, tidal and biomass among others are becoming more important because of increasingly restricted environmental constraints. Production of electrical energy using solar energy falls next to wind energy among all renewable energy sources.

The importance of renewable energy sources has been growing at a high rate as a result of being environment friendly. In particular, wind power is one of the most successfully utilized of such sources to produce electrical energy. The available wind energy depends on the wind speed, which is a random variable. For the wind-farm operator, this poses difficulty in the system scheduling and energy dispatching,...
The importance and conducting necessity studies on grid reliability evaluation have been increasingly important in recent years due to the number of black-out events occurring through in the world. Quantity evaluation of transmission system reliability is very important in a competitive electricity environment. The reason is that the successful operation of electric power under a deregulated electricity...

The optimal design of composite power system expansion planning is proposed in this paper. One of main keys of the successful power system expansion planning comes from optimal reliability level/criteria decision, which should be given for a constraint in the optimal expansion problem. However, it's difficult to decide logically the optimal reliability criteria of a transmission system as well as...
