Impact of Parameter Variations on the Steady State Behaviour of Grid Connected Renewable Energy Conversion Systems

This paper deals with impact of parameter variations such as wind speed, marine velocity and solar irradiation on the steady state behavior of grid connected renewable energy conversion systems (RECS) consisting of Wind Energy Conversion system (WECS), marine current energy conversion system and solar energy conversion system. A gird interfaced load flow program is developed in MATLAB platform 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 system is studied and the results are presented for a standard IEEE 9 bus system.
