scope:

This guide provides guidelines for the application of quick response systems of customer-side loads for utility operators in modern power grids. The definitions, classification and characteristics of rapid load response resources are elaborated. It provides complementary approaches for mitigating frequency stability issues of bulk power systems, and preventing power systems from quick frequency drops in emergency. Typical architecture, system implementation, testing and commissioning for quick response systems of customer-side loads are explored in this guide.

Purpose

In modern power grids, quick response loads should be measured or accurately estimated, controlled, and applied to realize power balance. This guide aims to provide knowledge base, shared experience, practice procedure and criteria on quick and flexible load control and response system. This guide also seeks greater utilization of quick response resources of customer-side loads, such as maintaining frequency drop stability in modern power grids.
