The system satisfies the peak-balancing needs of Zuid-Holland, Zeeland and largely Noord-Holland, while providing enough wind power balancing for Zuid-Holland till 2025.

2. An overview of fundamentals. Even though the goal of an RBS is to recuperate as much kinetic energy as possible during braking processes, it is also crucial for the system to decelerate the vehicle safely and comfortably. Brake safety and stability are major criteria in evaluating RBSs [18], [19], [20].
