Abstract:The transition to mass adoption of electric vehicles comes with challenges regarding the electric grid as simultaneous charging of electric vehicles might lead to overloads and outages. GridShield is a novel mechanism to prevent grid overloading due to simultaneous charging. In previous research it has been shown, through simulations, that GridShield is effective in the low voltage distribution network at preventing these overloads. In this paper, an automated generator, capable of producing the fictitious networks and necessary files for validating the GridShield system in various up-scaled simulation scenarios is presented. These generated networks fit to the specifications of real-world electricity grids in the Netherlands, along with a level of randomness to accentuate the validity of testing. Additionally, this paper presents a hierarchical implementation of the GridShield protocols as a solution for a multi-layered electricity grid. Simulation results show that each configuration significantly reduces the occurrence and duration of overloads without a significant reduction in energy served. Using the previously developed AIAD algorithm, the addition of GridShield controllers at the roots of the MV and LV distribution networks provides a 78\% reduction in overload occurrence while minimizing the duration of overloading to prevent damage to the grid.
