Integrated standardization theory has been applied to work on integrated standardization for the Smart Grid Scheduling and Controlling System (SG-SCS), aiming to improve the overall quality and coordination of technical standards for dispatching and controlling in power system which help to solve practical problems. This Paper presents the definition and history of integrated standardization, and introduces the method to develop integrated standardized work for the SG-SCS which contains 4 phases: preparation phase, planning phase, standard setting or revising phase and organizing and implementing phase. The objects for integrated standardization is analyzed and determined, while the objective is addressed as well. Analysis elements related to the SG-SCS systematically and ascertain the scope of those, for target decomposition of integrated standardization. Make the complex of standards plan based on former results and determine what standards we shall set or revising. Create a detailed work plan and execute it to form a coordinated complex of technical standards. Organize the implementation of standards, with a close-looped feedback work mechanics, the overall quality and reliability of standards for SG-SCS can be ensured. By carrying out the SG-SCS integrated standardization, problems such as partly duplication or Contradiction between old standards, the overall quality of standards is promoted, which helps to the operation and control of electrical power system.
