Modeling components of a DC coupled photovoltaic system with maximum power point tracking

Prices of Fossil Fuel prices increased steadily in past few years. Effect of greenhouse gases and its impact on global climate change is clearly visible. Alternative technologies for producing electricity are under current research focus. Among many renewable alternatives which have the potential to address these concerns Photovoltaic Cells (PV) could be considered a viable solution. Photovoltaic Cells capture solar radiation and convert it directly into electrical energy. A Shockley Diode equation based model was select to model solar arrays. A battery bank was modeled with parasitic model. They are located at the end user site and form a distributed generation system. The cost of generation of power by this method is higher than the conventional fossil fuel generation. Distributed generation or on site generation provide an added economic benefit in terms of reduced transmission and distribution losses and infrastructure investments. An electrical energy consumption site, Jadavpur University Saltlake Campus, Kolkata India, was considered to be powered entirely by solar power and impact of Maximum Power Tracking is studied for the same system. The Load of the system was forecasted using regression analysis.
