Conventional DC-link voltage-controlled voltage source converter (VQ-VSC) controls DC-link capacitor voltage and reactive power output by using phase locked loop (PLL) for synchronous grid connection of new energy sources such as PV. However, the deterioration ...
On the flip side, these systems suffer from double conversion losses — once when DC from solar panels is converted to AC for home use, and again when storing excess AC as DC in the batteries. Due to energy losses during these inversions, the maximum round-trip efficiency for today''s AC-coupled batteries is 90%.
This online program on electrical design will teach you to design and engineer the DC/AC side of a solar plant, post which you can install the solar plant. Once clients request a project, you will need to create a Bill of Material, create Build-To-Print drawings for your installation team, and much more.
