The VDE application rule ‘Connection and operation of generation plants on the low-voltage grid (TAR EZA NS)’ specifies the general minimum technical requirements that apply to the connection and operation of generation plants and storage facilities on the distribution system operator's low-voltage grid.
The general minimum technical requirements for the grid connection include grid connection principles, definition and design of necessary equipment as well as grid and system protection concepts. The general minimum technical requirements for operation include specifications on the behaviour of generation plants and storage facilities on the low-voltage grid with regard to grid security and system stability in the grid network.
The TAR EZA NS describes the general minimum technical requirements (here: for connection and operation on the low-voltage grid) in accordance with Section 19 (4) EnWG, which the German Association for Electrical, Electronic & Information Technologies has adopted as the authorised body. This ‘Grid Code with Grid Connection Regulations for Electricity Generators’ (Section 19 (4) No. 1 EnWG) is incorporated into the grid connection contract via the technical connection conditions (TAB) in accordance with Section 19 (1) EnWG. Requirements in the technical connection conditions that contradict the general minimum technical requirements are invalid.
