ESIF and Security at the Edge of Smart Grids

Thu, 02 Nov 2017 16:00:41 +0000

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.




Cryptocurrency in the IoT is more than just Blockchain and Bitcoin

Sun, 30 Jul 2017 22:18:33 +0000

Bitcoin <> Blockchain <> Cryptocurrency, although many folks talk like these words are synonyms. I prefer to refer to the family of technologies as Crypto-Chain (CC) here because not all blockchain is used for currency, and not all “blockchain” even uses blockchain.

Blockchain has its roots in the 1960s.Blockchain can be used to create a distributed consensus database, with plenty of hashing tossed in to make things secure...




Architectural Principals of Transactive Energy

Thu, 15 Jun 2017 12:48:57 +0000

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...




The Human Side of Energy Micromarkets

Wed, 14 Jun 2017 11:17:01 +0000

The Human Beings must have a say, or any model for transactive energy is doomed to failure. No model based on satisfying The Computers or The Grid will acheive prominence in the market. If optional, people will opt out. If mandatory, people will work around. The market is not a model for decision making, it is a pattern for interactions. In the abstract, semiotics does not determine meaning, only how meaning is conveyed. The interaction patterns do not determine the value of energy used at a particular place and time, they only determine how it is negotiated and conveyed.




Profiles for the Economic Actors in Distributed Energy

Tue, 13 Jun 2017 10:46:51 +0000

As this series continues its survey of Transactive Energy, we get, at last to what I see are the essential agent personalities. The Agent Personalities are a mid-level abstraction that makes it easier for the appliance supplier and the EMS/BMS maker to know what is being attached. Every appliance at the local store could be a pluripotent transactive agent, but this does not aid the brain-developer in understanding what you just bought. A wine cellar may not be on the list of known appliances, but it is useful to know that it is similar to the refrigerator and to an air conditioner in how it approaches...




Profiling Economic Actors for Transactive Energy

Mon, 12 Jun 2017 23:00:22 +0000

p>The communications defined in the common transactive services (CTS) can be used by every actor in transactive energy.

The needs of particular environments may require an actor to use different communications profiles. Security needs will be different for different environments. Security standards will change over time. Actors that participate only in small non-critical negotiations where both parties share a common owner may opt for lighter-weight standards to record transactions. These communications requirements will be expressed as profiles. These communications profiles will change over time without changing the fundamental information exchange between each actor.

There is profiling along a different dimension, profiling systems as economic actors




DER systems in the house and small business

Mon, 12 Jun 2017 11:00:56 +0000

The purpose of an energy management system (EMS) or building management system (BMS) in a home or commercial is to serve the owner or occupants of the home or building. Only secondarily is its purpose to “serve the grid”—and then only to the extent that it is rewarded for doing so in a way that supports its owners or occupants.

Every system in a house or building is a legacy system from the moment it is installed (manufactured, actually). No matter what standard we may posit for future use in home systems and home integration, most systems managed by the EMS or BMS will be...




Cryptocurrencies and Cybersecurity and Clouds

Sun, 11 Jun 2017 11:18:36 +0000

This post is part of the continuing Paths to Transactive Energy series. You can find them all listed by clicking on the matching metatag at the bottom of each post.

Many of the hottest startups in the Internet Of Things (IOT) are cloud based. This is driven by: are cloud based. Motivations driving this include:

  • Using powerful shared computing to reduce the cost of simple things in the house.
  • Pushing inter-Thing compatibility into the clouds
  • Providing a locus for high end user interfaces, on phone and tablet, over the web.

Of course a more powerful incentive is:




Money and Markets: digital currency, security, and resilience

Sat, 10 Jun 2017 12:27:37 +0000

When we start a conversation about Transactive Energy, most thoughts go immediately to government-backed currency, such as Dollars or Euros. The second thought may be digital currencies for which there are wide exchanges that can be immediately converted to a government backed currency. I name transactions made using these currencies as bankable transactions, because the proceeds of a sale can be deposited directly into a bank. Large transactive energy markets, such as those for the bulk power market operated in North America by the ISOs and RTOs, have to use bankable transactions.

At the other end of the scale, in a transactive market operating a home microgrid, perhaps entirely off the grid...




Transactive Energy in Deep and Shallow Markets

Fri, 09 Jun 2017 20:00:19 +0000

One of the most contentious areas of the CTS is how much information market participants and market makers should have about one another. The premises pit functionality vs. scalability, echo the arguments of stateless vs stateful communications, and have ramifications for personal fulfillment and personal privacy.
