VDI 4657 Blatt 3:2022-08 - Draft

This standard provides a basis for the selection and dimensioning of electrical power storage systems for use in different areas of application. It applies to the planning and dimensioning of electrical power storage systems for use in buildings connected to the distribution grid in accordance with VDE-AR-N 4105 and VDE-AR-N 4110. The main focus is on applications for optimising energy costs and relieving the load on the grid. The scope includes storage systems in the electrical power class from one to several hundred kW output or kWh capacity. It is aimed at all stakeholders who have to deal with issues relating to building energy systems, including building services planning companies, energy consultants, planning and installation companies, as well as manufacturing companies of electrical generation systems and storage systems. Due to the complex inter-dependencies, the standard does not provide support for use cases with electricity storage systems in which third parties are involved via external business models, for example through participation in energy trading. In addition, mobile storage, traction batteries of electric vehicles and vehicle-to-building use cases are not considered in the standard.
