Simulation of a Congestion Management Method for a High Penetration of Electric Vehicles in the Low Voltage Distribution Grid

Abstract:
High penetration of electric vehicles into the electrical grid requires a grid-friendly management method to decrease possible congestion issues. In this work, a congestion management concept was modeled and simulated. The concept can be implemented by low voltage distribution system operators and charge point operators through a communication protocol. This paper aims to investigate the effectiveness and efficiency of this management method on different penetration scenarios of electric vehicles by using Python and quasi dynamic simulation method in DIgSILENT Power Factory. The modeling of the electric vehicles, as well as other loads and small generators, was conducted with the Monte Carlo simulation and distribution data based on real measurements.
