MATHEMATICAL MODELLING OF HYBRID RENEWABLE ENERGY SYSTEM.

Abstract

Hybrid renewable energy systems (HRES) are becoming popular for remote area power generation applications due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. Economic aspects of these technologies are sufficiently promising to include them in developing power generation capacity for developing countries." Research and development efforts in solar, wind, and other renewable energy technologies are required to improve their performance, establish techniques for accurately predicting their output and reliably integrating them with other conventional generating sources. "This study summarizes the mathematical modelling of Hybrid renewable energy systems such as solar, wind, and storage devices". Wind and solar system required special technique to obtain maximum power due to their nonlinear power characteristics. "Due to the integration of two or more different source of power, an hybrid system has a complex control system. Of which its complexity increases with the maximum power point tracking (MPPT) techniques used within their subsystems."We describe methodologies to model HRES components, HRES designs and their evaluation". "The trends in HRES design show that the hybrid PV/wind energy systems are gaining popularity.
