Peak Load Shaving with Batteries – Isn’t that smart?

What does a power system make smart? Smart meters? Hm, … there are many possibilities to make the energy delivery smarter.

One interesting approach is to shave peak load with batteries. I guess this is known for decades! Isn’t it? More and more people are digging into the possibilities to do it in large scales.

A team of researchers has published an interesting paper with the title: “Using Batteries to Reduce the Power Costs of Internet-scale Distributed Networks”. They came to the conclusion that batteries could save up to a third of power costs … you don’t believe it? Read the paper:

IEC 61850 based monitoring and control systems could help to get the job done! The basic tools (embedded controllers with IEC 61850 servers and clients) are available. Let’s use them. Battery models are already defined (and under development) in IEC 61850-7-420. The following is a proposal for battery management for IEC 61850-90-9:

More battery related models are underway.
