Development of a grid-connected electricity supply system using solar energy

Abstract

Fossil fuels have been declining at a rapid rate and the use of fossil fuels has also been the cause for environmental hazards. Thus, there is growing concern globally on the need to look for renewable energy. Solar energy has been identified as one of main sources of renewable energy in the future. Singapore’s geographical location, with an average annual solar irradiation of 1,150 kWh/kWp/year and about 50% more solar radiation than temperate countries, makes solar photovoltaic (PV) technology a promising option as a source of renewable energy. Furthermore, Singapore’s urban landscape provides opportunities to develop capabilities in system integration and building integrated PVs that can be exported to the region. As such, the Singapore government has already made their official intentions clear that and identify the photovoltaic industry as an emerging industry. The report provides the details for the development of a grid-connected electricity supply system. In this report, there would be a literature review of Photovoltaic applications and its related theory. There would also be the discussion on the implementation, testing and analysis of the work done. The focus of the report would be on the research and implementation of DC-DC converter,DC-AC inverter and Maximum Power Point Tracking (MPPT) of Photovoltaic (PV)module. Details of some of the testing procedures and results for the design systems implemented would also be included in the report for discussions and verification. Lastly,there would be a conclusion to give an overall summary of the project and recommendations for enhancement to improve the systems designed.
