Battery charge controller for hybrid stand alone system using adaptive neuro fuzzy inference system

Abstract

Hybrid stand-alone power systems offer an achievable arrangement in remote and island zones where grid connection is not monetarily or in fact suitable. Nonetheless, the intermittent way of renewable energy sources and mismatch between the generated power and load demand are the principle challenge. In this way energy storage device is required to ensure efficient, reliable and secure power supply. An appropriate control for each generating unit and energy storage device is imperative. This paper proposes a DC linked hybrid solar wind energy system for stand-alone applications. Solar and wind energy are used as essential energy sources and battery unit is considered as a storage to take care of the load demand. Adaptive neuro fuzzy inference system is used to compute the panel voltage at which the maximum power can be tracked for solar system. It is likewise used to figure the maximum power created by nonlinear and irregular nature of solar and wind energy sources. A general power management strategy is intended for the proposed system to oversee power streams among the distinctive energy sources and charging and discharging of the battery in the system. A simulation model for the hybrid energy system has been created utilizing MATLAB/Simulink and tried for different irradiation, temperature and wind conditions.
