IMPROVEMENT OF POWER QUALITY IN ELECTRICAL SMART GRIDS

Posted by Lidia from University of LuxembourgResponsive · Innovative Products and Technologies · Luxembourg

Summary of the technology

The invention provides an algorithm to optimize the quality grid by compensating the effect of disturbances in terms of voltage harmonics and distortion power. The technology is based on the use of inverter-fed power devices with modern high-speed micro-controllers and an intelligent management of the different powers to be generated.

The compensation can be implemented on a self-sufficient single voltage generating power source running in stand-alone or grid-tied. It can also be shared and distributed on multiple voltage source inverters (VSI) of different powers connected on a utility grid.
