Design and Implementation of Fractional Proportional-Integral Control For Hybrid Solar and Wind System

Abstract

This paper addresses issues arise due to the integration of wind solar photovoltaic hybrid generation (WSPVHG) system with the grid. WSPVHG system minimizes the power storing requirements and improves the system efficiency. Here, power from solar system is controlled by integer proportional integral (PI) controller where as a fractional order proportional integral controller (FOPI) is designed for wind generation system due to its highly stochastic in nature. To achieve faster response, the inner loop is designed with FOPI controller and outer loop by integer PI controller. The FOPI controller is designed by using pole placement technique by utilizing the performance specification. The performance of the proposed system is tested with the real-time simulator (OPAL-RT).
