Dynamic load management for electric vehicles

What is dynamic load management?

Dynamic load management is used to control the charging power of electric vehicles. In contrast to static load management, dynamic load management uses the current residual load in the building to best provide available capacity to meet vehicle charging demand. Thus, the maximum charging power for the vehicles is dynamically adjusted, depending on the resiudal load at the grid connection point.

Gradual and limited charging of electric vehicles ensures that the physical limits of the local power grid (esp. grid connection) are respected to avoid overvoltage and power outages. At the same time, defined peak loads are avoided to reduce electricity costs. Load management is implemented via the software in the local controller to which the charging stations are connected. The control is based on the real-time measurement data of grid connection meter, sub-meter(s) as well as the (OCPP) data of the charging columns.

How is this different from static load management?

The main task of load management is to prevent overloads of the power grid and to reduce expensive peak loads. In contrast to static load management, dynamic load management allows the available network power to be used efficiently to avoid costly expansions, e.g. an expansion of the network connection or the line topology behind it.

The control of the charging power of the electric vehicles is done in real time, taking into account both the current power consumption of the building (residual load) and the available grid connection power (load management limit). This ensures that electric vehicles are charged safely and cost-effectively.

The following illustrations show in green the available load capacity with static and dynamic load management. On the one hand, you can see on the left that a static load capacity is always assigned additively to the (unmeasured) residual load; at the same time, you can see on the right that the load capacity is significantly larger in total despite a lower limit.
