    The automation of power system operation is generally achieved with the implementation of two control centers, one for the operation of the generation-transmission system and the other for the operation of the distribution system. These control centers are referred to, respectively, as the energy management system (EMS) and the distribution management system (DMS). The EMS may consist of several c... View full abstract»

    Distribution automation (DA) and demand-side management (DSM) have been the subject of discussion, evaluation, experimentation, and limited implementation for the last 10 to 15 years. At long last, it now appears the power industry is ready to proceed with full-scale implementation. The communication systems seem to be available and affordable, a number of suppliers are offering products specifica... View full abstract»

    Electric utility load research involves the systematic collection of customers' energy usage by time-of-day, month, season, and year. At many utilities, whole-premise and end-use load data are collected from a large number of customer sites at 15-minute intervals for multiple seasons and even years. Whole premise refers to the total load at a residence, while end-use load may include several indiv... View full abstract»

    Power monitoring units are inexpensive devices used to monitor distribution networks. In order to select and maintain power monitoring systems for a distribution network, it is important to understand some basic facts about the devices. This article categorizes power monitoring systems available today and highlights their relative strengths and weaknesses. Inexpensive electronic devices may be ins... View full abstract»

    Mexico's Laguna Verde nuclear power plant integrated its various systems, making fun use of the existing universe of signals and engineering. This article describes the plant's integrated information system. The development of this system enabled Laguna Verde to fully use the already existing universe of signals and its related engineering during all plant conditions, namely, start up, normal oper...

    For over 20 years, the North American Electric Reliability Council Operating Committee's (NERC-OC) Performance Subcommittee has been using the Control Performance Criteria (CPC) to evaluate the control performance of NERC's control areas. A new, more comprehensive CPC criteria is being put through its trial period by the Performance Subcommittee. The author reviews how the current CPC was develope... View full abstract»
