This paper addresses the review of components as photovoltaic panels, converters and transformers utilized in large scale photovoltaic power plants. In addition, the distribution of these components along this type of power plant and the collection grid topologies are also presented and discussed. 1. Introduction
Grid connection for commercial solar power plants is often 11 kV or higher, so it's usually necessary to step up the voltage using one or more transformers. The type of transformer should be selected based on the required capacity, its position within the electrical system, and the physical location and environmental conditions of the site.
To provide sufficient supply for the global energy consumption, a cumulative amount of 18 TW of photovoltaic power plants should be installed. This means the solar energy industry has a long way to reach to a point where at least 10% of the world energy consumption is generated by solar plants.
Therefore, the reactive power output of the solar-PV system can be expressed as a function of the solar-PV terminal voltage (V6) and the voltage at bus-4 (V4) as: (24) X 2 where Sr is the rating of the solar-PV, PS2 is the active power absorbed by the load from the solar PV and n is the step-up transformer turns-ratio.
As statistics shows, by the end of 2020, the installed capacity of world photovoltaic plants has reached to more than 751 GW. This indicates an increase of about 18.5% from the total of 634 GW solar plants that had been installed by the end of 2019.
