Prot4HiRES PROJECT (Nov/2021 - Oct/2023)

The high penetration of renewable sources in transmission grids may have a negative impact on the performance of protection systems for these infrastructures, as these protections have been designed for grids supplied by conventional power stations, where synchronous generators are used.

However, renewable sources use generators with interfaces based on power electronics, which characteristics differ from those of synchronous generators.

This project aims to identify the potential problems resulting from the introduction of renewable sources on the protection functions and, using laboratory simulation, determine what changes are necessary to the current philosophies of parameterization and coordination of those functions.

The final result will be a detailed specification for protection systems for transmission grids with a high penetration of renewable sources.
