Is your municipality prepared for a loss of power for days, or even weeks? The use of backup generators is really a short-term solution that only addresses one aspect of loss of power - what about the rest? Wireless communications? Clean water? Gasoline/diesel? Medicines? A holistic approach to energy from upfront and ongoing efficiency, minimizing demand, and designing, building, and operating long-term outage solutions is within the grasp of all munic...

Progress Energy Florida | EMTP-RV Investigation of Tertiary Connected Shunt Reactor Failure at Central Florida Substation

Progress Energy Florida installs switched shunt reactors on the 13.8 kV tertiary windings of their 500/230 kV transformer banks to reduce high system voltages during light load periods. Two 25 Mvar shunt reactors, Reactor #1 and Reactor #2 are installed on the 13.8 kV delta tertiary of the 500/230/13.8 kV autotransformer Bank #2 at the Central Florida 500 kV substation. The shunt reactors are switched with vacuum circuit breakers. Progress Energy Flor...

New York Independent System Operator (NYISO) | Controlled System Separation Study for Bulk Power Systems

The project investigated the feasibility of separating bulk power systems in a controlled manner for the purpose of maintaining stability in individual electric islands. A complex East Interconnection bulk power system model in PSS®E was studied in terms of different dispatch patterns. A broad range of disturbances was investigated for system dynamics. The outcomes of the project included: Identification of coherent groups of generators in the bulk...

Optimizing distribution operations | Intelligent Utility
Optimizing distribution operations By Doug Houseman Forty years ago Distribution engineers laughed at Transmission operators when they said they had to do state estimation and power flow balancing. Distribution did not have those kinds of problems and any imbalance could be handled on the feeder by moving a single phase transformer or two to rebalance the circuit. Distribution was simple, and to a large extent changes were seasonal in nature. Today...

Our Energy Future Do you want a say in the shape our industry will take? Then get involved! By Doug Houseman Time is not our friend. Coal generation will go away, with much of it gone by 2020 and little surviving beyond 2030. Once most of the coal is gone, we will see natural gas generation come under pressure to close down. Nuclear generation is not economically feasible today, and regulatory changes would be needed to make it viable. Expect to see ...

EnerNex hopes to develop next-gen grid management system | Energy Central
Electric utilities know that the growth of distributed energy resources, more informed and active customers, and new markets and regulations will force them to take shapes that are very different than the ones they have today. A Knoxville, Tenn.-based electric-power research, engineering and consulting firm has been working with Southern California Edison to create a foundation that can support whatever transformation electric utilities need to undergo....

Intelligent Underground Distribution Unearthing the potential in Smart Grid technologies By Doug Houseman After Hurricane Sandy, resiliency became a key factor in the modernization of the power grid. In looking at modernization and resiliency, underground was the first item on many lists. Undergrounding lines avoids many problems that people associate with outages. However, it has its own set of issues, not the least of which is cost—installing under...
