b) Deleted real-time electricity prices (see 3:4:2 of the:2015 version), direct load control (see 3:5:1 of the:2015 version), and emergency demand response (see 3:5:4 of the:2015 edition), capacity/ancillary service plan (see 3:5:5 of the:2015 edition), actual user load (see 3:6 of the:2015 edition), user response load (see 3:8 of the:2015 edition), direct benefits (see 3:9 of the:2015 edition), and aggregate benefits (see 3:10 of the:2015 version), ancillary benefits (see 3:11 of the:2015 version), etc:

c) The general requirements have been changed (see Chapter 4, Chapter 4 of the:2015 edition);

d) The requirements for absolute indicators have been changed (see 5:1, 5:1:2 of the:2015 edition);

e) Changed the indicator classification in the relative indicators (see 5:2:1, 5:1:3:1 of the:2015 version), the performance indicators of the subscription (see 5:2:2, 5:1:3:2 of the:2015 edition) and peak load performance index requirements (see 5:2:3, 5:1:3:3 of the:2015 edition);

f) Added the requirements for valley load performance indicators in relative indicators (see 5:2:4);

g) The technical principles of user baseline load have been changed to include fairness and rationality (see 6:1:1, 5:2:1 of the:2015 edition), precision and simplicity (see 6:1:2, 5:2:1 of the:2015 edition) and typical requirements for data (see 6:1:3, 5:2:1 of the:2015 edition);

h) The requirement to minimize the risk of demand response in the user baseline load calculation principle has been deleted (see 5:2:4 of the:2015 version);

i) Changed the requirements for data selection when the event occurs on a working day in the calculation method (see 6:2:2:1,:2015 edition): 5:3:2:1);

j) The comprehensive benefit evaluation of demand response has been deleted (see Chapter 6 of the:2015 edition);

k) Added benefit classification (see Chapter 7), benefit quantification and cost estimation (see Chapter 8);

l) Changed the description outlined in the benefit classification (see 7:1, 6:1:1 of the:2015 edition);

m) Changes have been made to the classification of benefits by the way benefits are obtained (see 7:2, 6:1:2, 6:1:3, 6:1:4, 6:1:5 of the:2015 edition), Requirements for classification of subject types (see 7:3, 6:1:6, 6:1:7, 6:1:8, 6:1:9 of the:2015 edition);

1 Scope

GB/T 32127-2024 sets out how demand response on the Chinese power system is monitored and evaluated. Demand response is paid for on the basis of load that did not occur, which makes it the only power system resource whose delivery cannot be measured directly: everything turns on the counterfactual baseline of what the customer would have consumed, and a baseline method that can be gamed turns the whole programme into a transfer payment. The standard sets the general requirements, the monitoring indicators, the calculation of the customer baseline load, the classification of the benefits, and the quantification of those benefits together with the estimation of the costs, with an informative annex working an example through. It replaces GB/T 32127-2015 and took effect on 1 December 2024.

This document specifies the overall requirements, monitoring indicators, user baseline load calculation, benefit classification and benefit evaluation of power demand response monitoring and evaluation: Benefit evaluation: This document is applicable to the analysis and evaluation of power demand response projects by power demand response implementation agencies, and the actual effects of the projects: Analyze and evaluate the comprehensive benefits of project implementation and provide reference for comprehensive resource planning:
