Hybrid renewable energy systems: Hybridization and advance control

As world´s power consumption is increasing regularly and consequently, demand for more power generation is inevitable. So this power demand can produce by Renewable energy resources up to some significant percentage of total demand. Wind turbine technology combined with solar photovoltaic (PV), as a hybrid system, can play an effective role to overcome our future energy consumptions with a cost effective energy conversion system. Integration of both resources is highly appreciated for providing a reliable power source to the world. In this paper hybrid energy system is discuss briefly, based on wind and solar photovoltaic. Next, integration schemes are illustrated by help of schematic diagrams, at last use of advance control techniques and their performance are given with future challenges.
