Smart Grid: David Kaplan and Steve Klein; Center for
Innovation and Entrepreneurship
Context, key concepts:
Smart Grid is:
- Rewarding
(business/econ development opportunity)
- Achievable
(core tech already exists; software/hardware yet to be written)
- Required
(essential to clean energy future; obligation to future generations)
Energy System Context:
- How
much energy is delivered through the grid, and not through the grid?
Renewables through the grid (hyrdo) are dwarfed by the amount of petroleum
and natural gas (transportation, space heating)
delivered external to the grid.
- No
silver bullets from single energy source (like hydro—already reached
capacity, will possibly decrease as snow pack decreases with climate change).
- We
must do everything we can so SAVE. Reduce energy consumption in order to
bring them back to 1990 levels by 2050.
- We
must take advantage of natural gas—smaller carbon footprint than carbon or
coal, useful in transition stage to take pressure off of clean energy
demand.
- Wind
improving in cost-effectiveness, but unreliable. Solar is more
predictable.
- Increase
in biofuels (not corn ethanol), but these are severely constrained in land
and water resources.
- Electrify
those parts of the grid that are amenable to it: vehicles.
- We
need to clean the grid; move away from carbon-based, combustible fuels.
Substations in the 10-15 kW range.
1 MW load = power to 1,000 houses.
Smart grid components:
- Energy
efficiency (making sure it’s cost-effective for the investment, retaining
maximum benefit)
- Communications
(some sort of telemetry between load center and customer demand;
distribution asset management)
- Smart
metering
- Demand
management
- Grid intelligent (smarter
substations, etc)
- All
sources (coal, natural gas, nuclear, hydro, etc) are integrated into the
grid
- Clean
power (large-scale implementation of clean energy sources, even if
unreliable)
- Electric
vehicles (two roles: late arrival into the grid, therefore coming in
information age, already information-able. Second: reducing carbon
footprint by getting people away from petroleum)
- Implementation
of storage (shock absorbers; no need to employ inefficient coal plants
when wind dies down, for example)
Utility perspective:
Visionary, but practical.
We need to take the least risk, lowest cost path.
Smart grid myths:
- Demand
response will not make that big of a difference on the West Coast. Not
that much variation between light/heavy load.
Strong advantages on the East Coast.
- Security
benefits: as we open it to connect with internet etc, it will actually be
more vulnerable to hacking.
- Increase
in knowledge/monitoring: many people will complain about lack of privacy.
Smart grid confusion:
- Installing
a smart meter is not the first step to a Smart Grid. No one element is a
defining element; there are many important components working together.
- GIS
and OMS are not Smart Grid components, but applications which enable it.
Drivers for Smart Grid:
- Legislative
and regulatory mandates and requirements (this is why it will take at
least a decade to implement)
- Customer
demands for more data, choices, and flexibility
- Developer
demands for integrating their distributed generation
- Electrification
of transportation
- Utility’s
own solid business case for modernizing the electric system, more
efficient, reliable and safe operations, meeting customer needs,
integration of distributed generation
Yet unimagined applications on utility and customer
sides—great potential for the future.
Who will be in charge of standards? NIST?
National Institute of Standards and Technology.
Telecommunication standards?
