Design and Development of High-Efficiency Power Converters for Renewable Energy Systems

Abstract

Throughout the late 1960s and early 1970s, industrialization accelerated globally.  Mass consumption and rising middle-class affordability of commodities, particularly in developing nations, were major contributors to economic expansion.  An indicator of economic growth is the global total energy consumption.  Climate change and global warming are the two main environmental effects of energy production and use.  Greenhouse gasses are released by all fossil fuels.  Deforestation for the purpose of extracting fossil fuels is combined with this.  On the other hand, greenhouse gasses are also produced by the energy used in industries.  Therefore, a total reliance on fossil fuels will make the issues of climate change and global warming worse. Properly combining the capacity of individual systems, such as wind generators and photovoltaics, is crucial to the hybrid power system's performance.  Both wind speed and instantaneous sun irradiation affect power generation.  However, the overall generation is also impacted by changes in the load requirements.  Studying the total yearly power generation for different PV-wind capacity combinations under various load scenarios is therefore required.  Additionally, a highly efficient power converter with a closed loop controller that can accept numerous renewable energy inputs needs to be developed. In order to determine the viability of a PV-wind hybrid system, a detailed model of the system's annual power generation and water production under specific site conditions must be created.
