3 1.1 Concept of DSM and Its Development Power crisis in California in early 2000s In early 1990s In 1970s, the oil crisis caused a sharp rise in energy prices. DR and demand side bidding (DSB) were introduced. Researches on and implementation of demand side management (DSM) began in China. Effective incentives were taken to induce changes in power consumption patterns by customers, improve enduse efficiency and achieve systematic power-saving management. DSM was introduced in USA. Technical Conditions on The Background of Smart Grid Demand Side Management Competitive Mechanisms of Power Market Smart End; Infrastructure of Measurement and Communication ; Analytic and Decision Method ; Standards of Smart Power Utilization. Demand Response (DR) Competitive Market Variety of Electricity Price; Sufficient Incentives

4 1.2 The Meanings of DSM Implementation Implementation of DSM fits the benefits of the whole society! Energy Independence Diversified Choices Market Stabilized Retailing Promotion Reliability Grid Company Customer Maximized benefits could be reached only by 九 the joint effort of customers, grid company and government!

10 2.3 Organizing International DSM Standardization Business IEEE P Guide for the Benefit Evaluation of Electric Power Grid Customer Demand Response 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 P were completed. Task summary and planning National standard development IEEE standard application
