Advanced solar inverters could be one of the biggest distributed energy resource communications and control points out there someday. With California now requiring at least early-stage “smart” capabilities from all new solar projects — and a standards road map for next-stage efforts like real-time communications and active controls — this future now has a template.
There are still a lot of unanswered questions about how smart inverters will be used.
That was the consensus at...
Distributed generation resources takes a giant step forward BY KEN GEISLER, Siemens For the majority of its existence, the electrical grid has been powered with large, remote “centralized” generation. Centralized power plants often need to reach substations serving load centers that may be...
How utilities can utilize multi-layered security approaches BY RICHARD CLARK, InduSoft Defense-in-depth is a security strategy first developed by military leaders in which multiple layers of safeguards are placed throughout a system. The concept behind the strategy is that it is more difficult to...
In recent years, the cost to bury high-voltage power lines has decreased dramatically. The American Transmission Company reports that installation costs for underground transmission lines (over 100 kilovolts) are now only 2.5 to 10 times the cost of an equivalent overhead line. Consequently, the...
The electric power industry is increasingly having to evaluate the growing penetration of distributed energy resources (DER). New sets of challenges exist for planning and operating the grid, especially with the distribution systems in which these new resources must be integrated. Now electric...
While condition monitoring is becoming an integral part of daily power grid operations, there’s a huge difference between simply checking on assets and truly proactive intervention. When a ‘check engine’ light goes on in a car, taking the directive literally and opening the...
A variety of factors influence the safety of those who work on utility lines. Many of the items are standard and likely on everyone’s line worker safety checklist. But there’s one that may not be top-of-mind when considering how to keep linemen and linewomen safe — the influence...
For many years the limit for normal apparatus loading was based on the maximum nameplate rating or an arbitrarily set value, called ‘the red line’. On-line monitoring of power transformers and circuit breakers for condition assessment has gained popularity over the past twenty-five...
Smart grid is an idea of upgradation of the traditional electric grid infrastructure. The efficiency of the existing electrical grid can be automated by integrating with innovative technical equipment such as: high-tech forecasting system, digital sensors, advanced two-way communication and...

Increasing the hosting capacity of distributed generation in power distribution systems is identified as key low-carbon solution to help meet the aggressive greenhouse gas emission reduction targets in the energy sector. The deployment of distributed generation technologies is creating a paradigm...
