Abstract
Technological innovations, economies of scale in manufacturing and innovations in financing have brought solar power generation within grid parity's reach in more and more markets.However, one of the key challenges in project development remains to design a PV power plant that is optimally balanced in terms of cost and performance for a particular site. The performance of a PV power plant can be optimized through a combination of resources. In our case, an optimized combination of transformer with on-load tap-changer and central inverter is considered in the PV park: The permissible current carrying capacity of the selected semiconductor modules and the required AC input voltage range of the central inverter at a certain grid node set the limit for the transferable power of the inverter unit. We have investigated how the use of an inverter transformer with on-load tap-changer affects the transferable power of the inverter by providing a small optimised input voltage range to the AC side of the solar Inverter.
