SMART GRID: Looking for a Definition

THE SMART GRID
PARADIGM
Since Electric Supply Industry (ESI) began
your path in the mid of XIX century,
Electrical engineers have tried to introduce
“intelligence” in generation, transmission
and distribution of electric energy.
Inventions as AVR, AGC, OPF, etc
show how intelligence is added to ESI.
When was the first time that You heard
About the smart grid ?
Since 2004 ESI is submereged
in profound changes. A new paradigm
called “smart grid”

2.- SMART GRID: LOOKING FOR A DEFINITION
“The smart grid is the integration of an
electric grid, a communications network,
software and hardware to monitor, control,
and manage the creation, distribution,
storage and consumption of energy. The
smart grid of the future will be distributed, it
will be interactive, it will be self-healing, and
it will communicate with every device.”

2.- SMART GRID: LOOKING FOR A DEFINITION
“enables the integration of utility
infrastructure, with buildings, homes,
electric vehicles, distributed
generation,energy storage, and smart
devices to increase grid reliability, energy
efficiency, renewable energy use, and
customer satisfaction, while reducing capital
and operating costs.”
Andres Carvallo, 2004

A Short definition:
Intelligent Infrastructure
Energy Infrastructure
SMART GRID is the convergence of three
very well established industries:
- The Electricity Industry
- The Telecommunications Industry
- The Information Technology Industry

The Smart Grid Functions according USA's DOE:
1.- Foundation: Smart grid deployments depend upon standards and best practices .
2.- Power Quality and Reliability: Distributed generation can improve system reliability
and address power quality
3.- Energy Efficiency: Smart grid sensing can be used to provide information to
consumers and operators for a more effective use of energy
4.- Operational Efficiency: Automated systems can bring greater value to system
operations.
5.- Clean Technology: The need to reduce or reverse environmental
impact is driving of variable renewable resources
6.- Economy or Capacity. Distributed Generation and Demand Response can help
shave peaks to AVOID, DEFER OR REDUCE investment in generation, transmission,
and distribution

Why Smart Grid: Environmental Causes
Environmental impact due to
Carbon-based economy
constitutes a fundamental driving force to
develop smart grid and ensure sustainability.
New technological advances allows distributed generation,
mainly renewable, be competitive respect to traditional
generation.
Then, Smart Grid should integrate, optimize, monitor and
control all distributed generation in order to mitigate climate
changes.
This means the end of economy of scale in centralized
power generation?

Why Smart Grid? Economical and Reliability Causes
The need for optimization of energy systems began after the 1973 oil embargo.
As a result, DEREGULATION has been applied in many countries worldwide
focusing on the maximization of the use of electricity infraestructure.
Market forces send strong incentives for generators but poor incentives to network
operators
HOWEVER RELIABILITY HAS BEEN A MAJOR ISSUE
Great blackouts happened in EU and USA in 2003 due to lack of monitoring and
control in electricity networks
The SG paradigm is the way to improve the monitoring and control of power
systems

NETWORKS ARE REGULATED AS NATURAL
MONOPOLIES AND REMUNERATED
BY MEANS OF USE OF THE SYSTEM (UoS) TARIFFS
UoS LOCATIONAL MARGINAL PRICING sends
adequate economical signals for efficient generation
location and operation.
UoS AVOIDED COST PRICING could be applied as a
strong strategy for efficient grid expansion under
the transition Smart Gri Stage.

THE CONCEPT OF GRID AVOIDED COST:
If Distributed Generation and Demand
Response are well specified, it is possible to
shave peaks to AVOID, DEFER OR
REDUCE investment in transmission and
distribution systems

Conclusions:
1.- SmartGrid Paradigm is founded on the fact of all
investments in control devices and optimization systems
will PRODUCE global AVOIDED COSTS
2.- If AVOIDED Costs are Real, Economy of scale due
to widespread implementation of smart grids SHOULD
be reflected on global energy market.
3.- Remuneration of natural monopolies (as T & D
systems) should integrate avoided costing tariffs for
Network Actors in order to ensure the correct
deployment of Smart Grids under this transition stage.
