T/CES 223-2023 Guidelines for evaluating the efficiency of hydrogen-electric coupling microgrids

Scope

Scope: This document specifies the general principles and methods for evaluating the technical performance and efficiency of hydrogen-electric coupling microgrids. This document is applicable to the evaluation of the efficiency of new, modified, and expanded hydrogen-electric coupling microgrids with a voltage level of 35 kV or lower, and a hydrogen generation device based on water electrolysis as the electro-hydrogen conversion unit. Main technical content: Hydrogen-electric coupling microgrids that generate hydrogen from distributed renewable energy are a new model for promoting the local consumption of new energy and advancing the development and utilization of hydrogen energy. However, there is currently a lack of relevant standards and norms for efficiency evaluation, resulting in inconsistent evaluation standards across different units or institutions, which hinders their large-scale and standardized development. The formulation of this standard is of great significance in responding to market realities, filling the gaps in existing standards, and serving the development of hydrogen-electric coupling microgrids. The purpose of this standard is to standardize the efficiency assessment and evaluation system for hydrogen-electric coupling microgrids, serving evaluation agencies, project owners, and microgrid operators.
