Abstract:
This paper study of an autonomous hybrid renewable energy system. Mainly, hybrid systems are divided into two categories as stand-alone and grid-connected systems. Since wind and solar energies are complementary in electric power generation from the complementarity of time and region; in stand-alone systems, energy provides by wind turbine and PV are the major renewable energy resources. Moreover, storage resources such as diesel generator (DG), battery, super capacitor bank, super conducting magnetic energy storage (SMES), and fuel cell-electrolyzer are used to overcome the intermittent nature of wind and solar energies. Stand-alone systems are the most promising technologies for supplying load in remote and rural areas. They provide greater reliability, higher efficiency and lower cost in comparison with using single resources technologies.
