What it covers
Sets the electromagnetic compatibility levels for industrial power distribution systems — the voltage distortion, harmonics, flicker, dips and transients a connected device should expect and must tolerate. For a BESS the standard defines the power-quality environment the PCS operates in: the harmonic limits at the point of coupling, the voltage-deviation bands, and the transient overvoltage levels the system must be designed to handle.
