A controller model for integration of hybrid energy system into the grid

Abstract

This paper introduces a controller model for the integration, of a wind system and photovoltaic system into the utility grid. The problem of integration of hybrid renewable energy based hybrid renewable energy generation system is that it relies heavily on weather conditions, PV and wind air speed. So, there is a necessity for developing control techniques for grid integration for such hybrid system, including a method for voltage and current control that stabilises the voltage and current. A PID control is developed in this work that is suitable for hybrid renewable energy system. Then, the system behaviour and performance are studied. For different weather conditions and fault condition systems, stability is also considered when there are change weather conditions in PV and air speed or a fault in the system. This paper advocates that the proposed PID controller gives a good performance. In this paper, solar energy is hybrid with wind energy. The developed MATLAB/SIMULINK design improves for integration of hybrid system performance and the results are presented.
