This paper presents an intelligent control framework in smart grids that integrate three renewable and nonrenewable energy sources for superior economical and environmental operations. The hydro and steam power plants are considered to be controllable energy sources while the wind turbine is treated as an exogenous energy source. The proposed intelligent feedback control framework optimizes the smart grid power generation by perfectly tracking the load demand fluctuations or by maximizing economical and ecological benefits under an uncertain renewable wind energy source. Numerical results demonstrate that the proposed framework is a viable approach to integrate various energy sources for real-time smart grid implementations.
