Steady State Analysis of Grid Connected Hybrid Renewable Energy Conversion Systems

This paper presents an analysis on steady state behavior of grid connected hybrid renewable energy conversion systems (RECS). Modeling of Doubly Fed Induction Generator (DFIG) for Wind Energy Conversion system (WECS) and marine current energy system ,and modeling of PV module is presented. A procedure for incorporating WECS, marine current energy conversion system and solar energy conversion system into a power flow program is discussed. A gird interfaced power flow program is developed in MATLAB and effectiveness of developed program is tested on a standard IEEE-9 bus system. The impact of varying wind speed, marine velocity and solar irradiation values on the steady state behavior of the grid connected hybrid power system is studied and the results are presented.
