Interaction between solar panels and energy-efficient lighting
This project concerns new types of power-quality phenomena that occur in installations with both solar panels and energy-efficient lighting (mainly LED).
The project will target households and offices, and especially consider three types of disturbances: waveform distortion below 2 kHz (even harmonics and interharmonics); waveform distortion above 2 kHz (supraharmonics); light flicker due to interharmonics and rapid variations in voltage amplitude. The project consists of measurements and simulations of disturbances in the power grid that originate from solar panels or lighting, direct measurements and simulations of the interaction between them as well as by experiments where lighting and solar panels are subjected to disturbances in a lab environment. The role of power electronics in the emission of disturbances and the interaction will be specifically studied in the project.
The project started at the beginning of 2016.
