Abstract: Nowadays energy need depends majorly on conventional resources and since, these resources are limited in supply; and the demand is increasing significantly, the focus is shifted towards the non conventional energy resources. Wind energy is one of the most trusted technologies in terms of cost of electricity generation hence, Wind Energy Conversion System (WECS) is deployed for meeting the needs. In this paper durability and control of hybrid Wind/Battery system has been investigated. The choice of hybridisation increases the efficiency of the system considering the intermittent nature of wind flow. This off grid system is highly needed in areas like coastal regions and isolated areas where transmission lines cannot be installed easily. To ensure controlled charging/discharging of battery, state of charge has been developed and the mechanical safety of the WECS has been assured by means of the pitch control technique. Both of these control strategies have been integrated and the efficacy has been validated by testing the system with various load and wind profiles in MATLAB/SIMULNIK.
