As increasing numbers of "smart" sensors and actuators are introduced into the electrical grid, the cyber security factor grows in significance, necessitating the implementation of information assurance controls for devices at all levels within the grid communications network. Determining the appropriate controls for any particular device first requires identifying its place within an established...
This paper proposes an application of low cost IPv6 based wireless sensor network in distributed generation. The wireless sensor network used in the proposed scheme is based on IEEE 802.15.4 link layer technology and the sensor nodes have the ability to communicate directly with other IP devices via internet. A web based service is appreciated for implementing the proposed smart power distribution...
The emergence of cloud computing has established a trend towards building massive, energy-hungry, and geographically distributed data centers. Due to their enormous energy consumption, data centers are expected to have major impact on the electric grid by significantly increasing the load at locations where they are built. However, data centers and cloud computing also provide opportunities to help...
This paper describes the experience from the world first installation of Smart High Voltage substation with IEC 61850 Process Bus where IEEE 1588 Time Synchronization and dynamic multicast filtering have been used. IEC 61850 is one the 30 standards identified by NIST as key elements for achieving interoperability in the Smart Grid. This paper describes the experience from a high voltage substation...
This paper discusses the challenges and approach to using responsive load to supply ancillary services in the smart grid. We discuss the types of demand response and ancillary service they would provide by describing spinning reserve, regulation, etc., along with the needed response time and duration. The benefits of supplying ancillary services from loads instead of generation are covered, along...
