Dimensioning Solar Collector Power Transformer Based on Loading and Ambient Temperature Profile

Solar power generation is an intermittent power resource, and the transformers providing the grid connection are mostly used below their power rating. An economic analysis in combination with fulfilling technical requirements can be used during the procurement process to reduce the installation cost and promote the faster expansion of renewable power generation. To meet ambitious global targets of a sustainable power system, new solutions for connecting renewable energy to the grid are required. This methodology for dimensioning the step-up power transformer of the collection grid for a large photovoltaic power plant through optimization based on technical and financial variables.
