Design 50MW large scale PV power plant considering Bangladeshi climate

Abstract: Conventional electricity production is undergoing a major transition, and renewable energy projects are playing an important part in this shift. An opportunity exists to use the naturally high solar radiation resource to meet the high electricity demand. This research investigates the design of a PV solar power plant with a capacity of 50 MW which has been modelled on the conditions of Dhaka, Bangladesh.  The PV plant comprises PV modules, mounting structures, inverters, transformers, switching circuits, and DC and AC cables. The calculations of parameters have been done for a specific area with the main objective to ensure the optimal tilt angle for the plant. Then, the performance of the proposed methodology for defined parameters is tested through specialized software ‘PVsyst’. Later, the results are compared for different tilt angles to validate the effectiveness of the proposed framework. It is found that the best optimal tilt angle is 25-degree. The projected energy output has been determined to be 82387 MWh per annum with a payback time of 5.5 years and a reduction of CO2 pollution by 1202851.5 tonnes per year for proposed work. Moreover, the calculation methodology used is divided into system design calculations, energy calculations, and assessment parameters calculation. The primary goal of the comprehensive calculations is to obtain the system's Annual Energy Production (AEP). Financial calculations are used to calculate the cost of the PV system as well as the Levelized Cost of Energy (LCOE).
