  • Security, trust, and QoS in next-generation control and communication for large power systems

    The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. A flexible, real-time data network would make it possible to use these data for many more control and protection applications, potentially increasing the grid's ...

  • More Power. More Control.

    Cuyahoga County pumps value to its community through greater control, standardization and technological advancements. Cuyahoga County is the most populous county in Ohio, with nearly 1.4 million residents. Part of Greater Cleveland, the county is named after a Native American word meaning "crooked river." With more than 63% of its total area made up of water, the county strives to foster strong ...

  • Control of the regimes of the electric power systems and deregulation

    This paper presents a survey of characteristics, balances, stabilities, reliability and regimes of Electric Power Systems (EPS) and Interconnected Electric Power Systems (IEPS). They are the most complicated and important 'machines' that have ever been created by humankind. Introduction of deregulation in the EPS will require and impose new systems, new algorithms and new rules for control. EPS ...

  • Application of hybrid fuzzy PID controller for three–area power system with generation rate constraint

    This paper presents a new approach for load frequency control of three–area interconnected reheat thermal power system with the consideration of generation rate constraint (GRC). The PID–type fuzzy controller is combined with a conventional PID controller to enhance the performance and robustness of the controller. The proposed controller called hybrid fuzzy PID (HFLPID) controller has been ...

  • Controlling the power balance in an 'empty network'

    This paper presents the concept of an 'empty network' and shows how the power balance can be controlled in such a system. In this study, an 'empty network' is defined as a transmission system in which no rotating mass is present. All generators are connected to distributed systems and 'hidden' behind power electronic interfaces. One generator creates a neat 50 Hz voltage that serves as a ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...
