Optimisation and techno-economic analysis of autonomous photovoltaic-wind hybrid energy systems in comparison to single photovoltaic and wind systems

摘要

A techno-economic analysis for autonomous small scale photovoltaic-wind hybrid energy systems is undertaken for optimisation purposes in the present paper. The answer to the question whether a hybrid photovoltaic-wind or a single photovoltaic or wind system is techno-economically better is also sought. Monthly analysis of 8 year long measured hourly weather data shows that solar and wind resources vary Greatly from one month to the next. The monthly combinations of these resources lead to basically three Types of months: solar-biased month, wind-biased month and even month.
