Fallacies in the Implementation of a Local Micro Smart Grid

The implementation of local micro smart grids has become relevant for many people and poses a milestone on the way to a more sustainable future via efficient usage of locally generated renewable energy. Building a micro smart grid requires integration of decentralized production capabilities, public and private charging infrastructure for electric vehicles, as well as smart control mechanisms to respond to energy demand in real-time. Due to the variability and individuality of such systems, there is as yet no codified way to set them up. Although implementation and operation may seem simple, some pitfalls need to be considered when theory meets reality. In this research paper, we would like to share our experiences from building a micro smart grid in a real-world scenario and describe some of our faulty assumptions and unforeseen technical challenges we encountered during the process. This article is intended to serve in particular as a guide for anyone planning to build a micro smart grid, helping them to avoid annoying and potentially costly mistakes right from the start by planning ahead. In this way, it is especially meant to serve as a thought-provoker and an additional checklist.
