Note 2 : Au sein du TC 8, le SC 8C agit de manière coordonnée avec les SC 8A et SC 8B sur des sujets comme la connexion des sources d’énergie renouvelables, des microgrids et des systèmes énergétiques décentralisés, et leur impact sur les systèmes électriques.
General Information
IEC TS 63384-2:2026 addresses the quantitative assessment of power system stability and security. Its purpose is to provide guidelines encompassing the use of terms and definitions, as well as the objectives and general requirements for conducting quantitative assessments. The TS includes the classification of stability and security, classification of quantitative indices, and key considerations for implementing quantitative assessments.
The TS is applicable to various domains, including system planning, operation planning, operation control, stability control system design, and stability control decision planning, as well as software, equipment, and systems for the secure and stable operation of the power system.
The stability and security quantitative assessment techniques specified in IEC TS 63384-2 are independent of any specific software, equipment, or systems used for the secure and stable operation of the power system.

IEC TS 63384-1:2023 provides guidance for power system stability control framework design. It covers the uniform use of terms and definitions, general objectives and principles for power system stability control, the classification of power system stability control, and the framework combining several types of stability controls in a coordinated and cost-effective (risk-based) manner.
In accordance with this guideline, the framework is designed to cope with disturbances of different probabilities of occurrence and impact on power system security and stability. Effective control approaches are designed to prevent or minimize the scope of future blackouts.

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
