Abstract: As our reliance on traditional power grids continues to increase, the risk of blackouts and energy shortages becomes more imminent. However, a microgrid system, can ensure reliable and sustainable supply of energy for our communities.

1. Introduction Microgrids offer a viable solution for integrating Distributed Energy Resources (DERs), including in particular variable and unpredictable renewable energy sources, low-voltage and medium-voltage into distribution networks.
One appealing residential microgrid application combines market-available grid-connected rooftop PV systems, electrical vehicle (EV) slow/medium chargers, and home or neighborhood energy storage system (ESS). During the day, the local ESS will be charged by the PV and during the night it will be discharged to the EV.
The PrInCE Lab microgrid is a low-voltage radial distribution network structured as a TN-S system. It encompasses four different generation types along with a Battery Energy Storage System (BESS) and two load banks. Generators can be differentiated on the basis of the primary energy source used into renewable and non-renewable energy sources.
Two different control loops have been implemented to resynchronize the microgrid to the main grid. The first one is based on an active method which forces the master unit to adjust its active and reactive power outputs to rapidly adapt the overall system frequency and voltage magnitude to the reference signal.
