The background and context of VDE-AR-N 4100
The low-voltage grid is the part of the power system that connects customers' installations to the distribution network. It operates at a nominal voltage of up to 1000 volts AC or 1500 volts DC. The low-voltage grid is essential for delivering electricity to households, businesses, public facilities, and other consumers. However, it also faces some challenges and opportunities due to the increasing integration of new technologies such as electric vehicles, accumulators, and renewable energy sources. These technologies can affect the power quality, reliability, safety, and efficiency of the low-voltage grid. Therefore, they need to be regulated and coordinated by technical connection rules.
The technical connection rules for low-voltage networks in Germany have been developed by the Forum Network Technology/Network Operation (FNN) in VDE. VDE is the Association for Electrical, Electronic & Information Technologies, one of the largest technical and scientific associations in Europe. FNN is a technical standardization body within VDE that deals with network technology and network operation issues. FNN works with experts from network operators, manufacturers, service providers, associations, authorities, research institutes, and other stakeholders to create user-friendly rules and standards for the power system.
The latest version of the technical connection rules for low-voltage networks is VDE-AR-N 4100. It was published in April 2019 and came into effect in September 2019. It replaces nine previous sets of rules that were applicable for different aspects of the low-voltage grid. By creating a new, standardized basic set of rules for this voltage level, FNN aims to simplify and harmonize the requirements for grid operators, electricians, manufacturers, and customers. Moreover, FNN intends to make innovative technologies such as accumulators and electromobility suitable for everyday life and system-compatible at a faster pace.

VDE-AR-N 4100 introduces some key innovations and changes compared to the previous sets of rules. Some of them are:
The mandatory registration of charging devices for electric vehicles with a rated power greater than 3.6 kW. This is to ensure that the grid operator can monitor and control the load on the low-voltage grid caused by electromobility.
The technical requirements for accumulators that are connected to the low-voltage grid or to power generating plants. These include the network-beneficial behavior of the accumulators, such as providing reactive power support or frequency response.
The network-beneficial behavior of all consumption systems that are connected to the low-voltage grid. This means that they should contribute to maintaining or improving the power quality, reliability, safety, and efficiency of the grid. For example, they should avoid causing voltage fluctuations or harmonics.
The simplification and harmonization of the forms, processes, and deadlines for registration, notification, and approval of consumption systems. This is to reduce the administrative burden and increase transparency for all parties involved.
The alignment with other relevant standards and regulations at national and international levels. This is to ensure consistency and compatibility with other technical connection rules at higher voltage levels or in other countries.
VDE-AR-N 4100 requires that all consumption systems that are connected to the low-voltage grid comply with its rules. This applies to both new and existing systems. However, there are some transitional periods and exceptions depending on the type and date of installation of the system. For example:
Charging devices for electric vehicles that were installed before September 2019 do not need to be registered unless they are modified or replaced.
Accumulators that were installed before April 2019 do not need to comply with VDE-AR-N 4100 unless they are modified or replaced.
Power generating plants that were installed before April 2019 do not need to comply with VDE-AR-N 4100 unless they are modified or replaced.
Meter boards and cable entries that were installed before April 2019 do not need to comply with VDE-AR-N 4100 unless they are modified or replaced.
Overvoltage protection devices that were installed before April 2019 do not need to comply with VDE-AR-N 4100 unless they are modified or replaced.

FAQs
What is the difference between VDE-AR-N 4100 and DIN EN 50160?
VDE-AR-N 4100 is an application rule that defines the technical connection rules for low-voltage networks in Germany. It specifies the requirements for the connection and operation of consumption systems on the low-voltage grid, such as charging devices for electric vehicles, accumulators, power generating plants, meter boards, cable entries, overvoltage protection devices, and more. It is based on the national and international standards and regulations that apply to the low-voltage grid.
DIN EN 50160 is a European standard that defines the voltage characteristics of electricity supplied by public distribution networks. It specifies the limits and tolerances for the frequency, magnitude, waveform, symmetry, and quality of the voltage at the customer's supply terminals. It is based on the technical and economic conditions that apply to the public distribution networks in Europe.
Therefore, VDE-AR-N 4100 and DIN EN 50160 are related but different documents. VDE-AR-N 4100 sets the rules for how consumption systems should be connected and operated on the low-voltage grid, while DIN EN 50160 sets the standards for how the voltage should be delivered by the public distribution networks.
