scope:

This recommended practice focuses on the factors that should be considered for planning, operating, and maintaining distribution networks such as risk factors and event identification, classification of risk types, equipment and network risk evaluation, risk grade classification, risk early-warning, risk prevention control, risk dynamic tracking, and risk simulation. This recommended practice not only applies to operations risk evaluation but also provides guidance toward the planning, construction, and maintenance of traditional distribution power system, micro-grid systems, and smart distribution networks with access to large-scale distributed energy resources (DER) and flexible loads.

Purpose

This recommended practice identifies and assesses risks and provides technical guidance and methods for smart distribution networks in the planning and operation stages. The implementation of this recommended practice will provide support for improving planning and construction plans and changing the operation mode to enhance the safe, reliable, and economic operation of distribution networks, advance the use of distributed generations, and promote the development of relevant industries and the technological progress of risk identification and evaluation.
