Energy demand is increasing day by day due to globalization and papulation. So that by using non-renewable sources we cannot reach this energy demand because of increased cost per generation. And also from these sources pollution occurs is also more. So that if we use renewable sources, we can meet this energy demand. This paper gives review on different optimization methods of HES such as by using Artificial intelligence methods, by using software tools, by ensuring maximum energy production from low cost energy sources, by using DSM strategy and by using hybrid models. Finally, comparison and results are discussed. P. Mahesh | D. Srikanth | K.
