IEC/TS 63276 Ed. 1.0 en:2024 PDF

This document specifies methods for the evaluation of the maximum export capacity of distributed energy resources (DER) that distribution networks can accommodate. It provides guidance on the technical constraints that should be considered in evaluating hosting capacity, information required to be collected to undertake a hosting capacity evaluation, and evaluation methods.

This document is applicable to AC distribution networks operating at a nominal frequency of 50 Hz or 60 Hz.

This document does not specify allowable values of system parameters that can be impacted by the addition of DER on a distribution network, such as maximum or minimum voltage, maximum current, etc. These values are to be determined by the user, from international or national standards, local regulations or the like, and used as an input to the evaluation methods described in this document.

Options for increasing the hosting capacity of distribution networks are not specifically considered, although the identification of constraints to the hosting capacity will assist users in developing methods for increasing the overall hosting capacity.

This document is mainly used by distribution system operators (DSO) and other organizations with corresponding qualifications and capabilities. The evaluation results can serve the DER investors, DSO, energy sector regulators and other stakeholders as a decision-making basis.
