Daedalus was the mythical engineer and artificer of the classical world. What would he do with digital tools and digital concerns?

Cybersecurity of Power—Resources

June 27, 2019 in Cybersecurity, Distributed Energy, Paths to Transactive E..., Security, Smart Grid

As we work to define the cybersecurity of things, power demands its own security models, outside of SCADA security and distributed controls. Power is both a resource and a vector, and each of these offers vulnerabilities to cyberattack. This article describes cybersecurity of the resource.

ESIF and Security at the Edge of Smart Grids

November 02, 2017 in Microgrids and Distrib..., Security, Smart Grid, System Architecture

I attended the NREL ESIF Cybersecurity Workshop last month. ESIF names the Energy Systems Integration Facility. The workshop demonstrated both what should be done to secure future energy systems, and how difficult, labor intensive, and non-scalable this is using standard practice.

The first morning showed off the ESIF’s model of how to secure the un-securable.

Architectural Principals of Transactive Energy

June 15, 2017 in Microgrids and Distrib..., Paths to Transactive E..., Services, Smart Grid, System Architecture, Transactive Energy

Transactive energy describes a pattern of integration where parties exchange the value or a commodity resource [power] over time and make forward commitments to sell or purchase that commodity. The Common Transactive Services (CTS) can be used in central auction-type systems, where a single entity announces or broadcasts prices or in markets were two or more parties come to a mutual agreement on price and delivery.

All forward transactions are committed, that is one party commits...

Eight Agents for Energy

October 21, 2016 in Distributed Energy, Energy, Microgrids and Distrib..., Smart Grid, Transactive Energy

The Energy Mashup Lab (The Lab) is developing open source software for agents that will enable systems that use, produce, or store energy to self-assemble into microgrids. These microgrids can be standalone or grid-attached. If grid-attached, they present a single market or OpenADR interface to the grid, and that interface reveals only the net market position of the microgrid.

The microgrid is operated by a micromarket, trading in availability over time. The Lab uses ...

New Daedalus

Daedalus designed buildings, automated statues, and built wings for human flight. Daedalus worked by eye and hand, his designs scratched with a stylus on wax tablets. Until recently, we merely perfected his means of work, using better pens, and paper, and finally drawing on computers.

It is only recently that we have begun to leave the methods of Daedalus behind.

Simulations and digital twins guide each decision. Intelligence, or at least behaviors, imbue each system and device. Cyberphysical systems replace household servants and chauffeurs, operate factories, and manage energy logistics. The most pressing concerns are how intelligent systems and buildings will respond to us, and to each other.
