The
Internet of Things is being built to mash. Maybe it is because the
initial devices are so simple, providing a service with a single
command. Lock the door. Alarm the house. Answer the door. The low cost
integration that the cable companies demand rewards not looking under
the hood.
Last month, I had the pleasure of a tour of a home microgrid system
ready to mash. With care and good math, it can compensate for the
incidental on-demand dumb loads of the house. If those loads are ready
for an energy mashup, it can do better. In the AllSeen Alliance,
appliances and domotic apps are already built to mash functionally.
AllJoyn leaf nodes for cuisine and for lighting and fireplace scenarios
can mash for the perfectly planned evening. AllJoyn routing nodes can
enable the apps to coordinate their behaviors.
Modern appliances act as apps in themselves. My washer can query my
phone which snapped a picture of a barcode in a garment to program a
wash load. But even smart appliances also use resources that affect the
whole home, notably energy and hot water, and make noise that might
interfere with the romantic evening scenario currently running on the
lighting manager.
With a resource framework, resources limited by policy or by firm
supply limits can be shared, allocated, smoothed over time through
cooperation between the apps. A mashable microgrid can cooperate with
these appliances and apps to optimize resource use over time.
Optimize is of course a nebulous word unless one asks “optimize for
what?” Does one optimize for lowest peak use, longest battery life, or
for energy security? Does one optimize for high energy import before
the storm, or for energy export for revenue, or for economic
cooperation with the neighbors? The answer should be: whatever the
homeowner wants.
OASIS Energy Interoperation is becoming recognized as the interface for
economic resource mashups. In the NIST Transactive Energy Challenge, it
is demonstrating the ease of reconfiguration and the resilience of
rapid response in secure multi-facility mission-critical environments.
In the mashable home, it is readying integration-free resource
smoothing, making each home a more valuable participant in a larger but
still local community. Mashups across neighborhoods, and between homes
await only reglatory relief.
As one moves into larger containing microgrids, or into more critical
facilities, a mashable market requires greater security. With economic
interfaces, each system or microgrid communicates only through an
energy services interface, and hat interface is a security firewall;
fractal microgrids intrinsically support defense in depth.
As one moves from inside the home to outside the home, inside the
commercial building to the business district, there is also a change in
economic constraints. In a micromarket that operates a home, all
participants are all playing with the dealer’s chips. As we move into
bases and neighborhoods, different owners and different bank accounts
come into play.
Blockchain names a set of technologies that can make official
inalterable records without central authority. Blockchain can be used
to manage identity, contracts, and transactions. Bitcoin is a
well-known type of blockchain, but far from the only one. IBM and
eleven major banks are currently working together on open source for a
bankable blockchain, i.e., one in which decentralized transactions can
eventually move up into the banking system.
In the Internet of Things, some relationships and some purchases may be
too small to warrant central registration. Even a central authority for
identity of small things threatens privacy and security. Central
approval is too expensive to support nano-transactions. Blockchain can
track device description, functions, locations, and price, if the
device is ready to be hired or bought. Blockchain can record smart
contracts without an intermediary for granting authority or permission.
Payments and bartering simplify integration of diverse systems.
Micro-payments and even nano-payments could enable negotiations to buy
into the HOV lane, air rights for delivery drones, or even real time
negotiation for five minutes of Wi-Fi time from the vending machine.
Blockchain opens up an intriguing decentralized model for economic
mashups. A home micromarket can operate with simple bilateral trades or
a managed double auction. Micromarkets that span cities or regions may
need central trading floors and complex matching of transactions that
might bundle storage, power, transmission, and other purchases into a
single trade. A neighborhood is somewhere in-between.
Economic mashups can simplify trading between resource types. A routine
CHP decision trades value between generating heat and power, and the
current demands for each across a market. Cooling demands may rely on
absorption or compression chillers, that is on making dynamic choices
between using a thermal market or a power market to supply a third
market. District energy may place the two thermal markets (heat and
cold) external to each facility. CHP, especially CHP with cooling,
usually relies on careful and expensive static analysis. Economic
mashups just might make the home CHP economical.
Neighborhood micromarkets are driven in part by a desire for
resilience, i.e., for operation during central infrastructure failure.
Neighborhood micromarkets can be justified solely for enabling
distributed energy resources to be used locally, without transmission
loss or new transmission infrastructure. Each of these motives, along
with the capability of defense in depth, comes into play in the Camp
Pendleton microgrids.
Owners of home microgrids may want to trade amongst themselves after
the storm. With telecommunications potentially down as well, they want
to trade using enforceable contracts without central approval or
authority. Such markets must be mashable, because even if all homes in
a neighborhood start with the same technology, over time each homeowner
will make his own decisions on upgrades.
The IoT is made for mashing. Economic mashups enable allocation,
balancing, and smoothing of resource use within a micromarket. Multiple
micromarkets will be able to self-manage across resources in the same
facility.
