Demand Side Management

Demand Response(DR)

DSM was introduced in USA.

Power crisis in California in early 2000s

In early 1990s

In 1970s, the oil crisis caused a sharp rise in energy prices.

Researches on and implementation of demand side management (DSM) began in China.

DR and demand side bidding (DSB) were introduced.

Effective incentives were taken to induce changes in power consumption patterns by customers, improve end-use efficiency and achieve systematic power-saving management.

Establishment of DSM Standardization Technology Committee

In December 2012, the Electric Power Research Institute of CSG applied to CEC for

the establishment of the DSM Standardization Technology Committee.

It is intended to prepare a total of 23 DSM and DR standard systems falling into

three categories and eight series as the standard basis of the implementation and

technical and economic evaluation of DR projects and the energy savings and energy

efficiency assessment of power grids and enterprise customers.

2.2 Establishment of DSM StandardizationTechnology Committee

2.3 Organizing International DSM StandardizationBusiness

In 2012, the data of electricity use of more than 40 customers involved in DR were collated and analyzed, and many technicians and experts were consulted for comments. The environment of DR implementation in different countries

was taken into account.

In 2012, the Electric Power Research Institute of CSG led the

development of the national standard - Guide for the Benefit Evaluation of Electric Power Grid

Customer Demand Response.At the end of 2012, Beijing,

Foshan and others were determined to be the DSM pilot

cities to test the standard.

In October 2013, the standard was approved as a project (No.

P2030.6) by IEEE.In November and December

2013, the outline of and descriptions for IEEE P2030.6

were completed.
