Focus
Smart Grid
Increasing complexity of power grids, growing demand, and requirement for greater grid reliability,
security and efficiency highlight the need for a quantum leap in harnessing advanced solutions.
ReliabilityReliable energy delivery has significant impact
on the amount of revenue collected by DSOs
and can influence regulatory decisions about
rate increases or funding for specific projects.
Municipal and cooperative utilities are focused
on keeping electricity supplies inexpensive and
continuous, so solutions that increase reliability
are important to them.
Replacement of aging equipment with devices
that can be remotely monitored or controlled
has enormous implications to reducing the
frequency and duration of outages.
EfficiencySmart Grid infrastructure is expected to
improve grid efficiency by reducing line losses
in the distribution network.
Through networking distribution automation
devices, reactive power flows are minimized
using adaptive voltage control to monitor and
adjust voltages at critical points throughout the
distribution system.
IntegrationWith the increased penetration of renewable
generation, the grid is experiencing a shift from
predictable dispatchable generation to variable
non-dispatchable generation.
This adds a new level of uncertainty and
volatility to the grid that causes an array of
problems as the relative proportion of variable
generation vs. traditional dispatchable
generation increases.
Grid integration of renewable energy sources
meaning control and energy storage solutions
are key to minimizing these effects.

Smart Automation in MV/LV transformer
substations
Page.: 20Date: March 2012 Open Smartcity 2012 - Copenhagen
Introduction
Smart Automation
The automation of MV/LV transformer substations is an essential step in the transition of the
distribution system towards the Smart Grid.
• Smart transformers provide significant benefits:
• enhance operation and maintenance
• increase reliability of supply
• When conveniently assessed, these impacts:
• reduce the cost of interruptions for electricity consumers
• increase regulatory incentives to be perceived by DSOs
Page.: 21Date: March 2012 Open Smartcity 2012 - Copenhagen
Smart Automation
In addition to pure voltage transformation, smart transformers:
• Monitor multiple variables of the system, carry out load-flow analysis and detect any anomaly:
• Fault detection and localization
• Phase unbalance
• System security
• Network diagnosis or event predictive maintenance
• Process data providing autonomous decision making providing self-healing capabilities:
• Manage alarms
• Act in emergency cases: weather events, terrorist attacks, cyber threats.
• Control via remote operation and maintenance, coordinating and performing:
• fault isolation
• service restoration
• Store energy, with smart charging profiles that contribute to flattening demand curves
The MV/LV transformer is the main entrance to the distribution gate (I)

– Early detection of failures before they occur :
– Predictive Maintenance, by detecting partial discharges caused by insulation defects in the system
– Discrimination between the different types of discharge (those produced in the cable, in the joints, in the
transformer…)
– Correctly guide investments to the power system areas that really need it (with objective data)
– Minimize the problems when receiving the installation by third parties (industrial parks, residential areas...)

Conclusions
Page.: 41Date: March 2012 Open Smartcity 2012 - Copenhagen
Conclusions (I)
Smart Automation
The technical analysis precisely determines how the automation of MV/LV transformer substations
improves the network and the reliability of supply.
DSOs must consider the benefits they are allowed to perceive according to the regulation, which
varies throughout the different countries
DSOs, who decide whether to embark upon
such investment project
Beneficiaries are:
Consumers, who will suffer from less frequent
and time extensive interruptions
Page.: 42Date: March 2012 Open Smartcity 2012 - Copenhagen
Conclusions (II)
Smart Automation
The automation of the distribution system is becoming more and more important under the
current paradigm of Smart Grid
Assessment and simulation are key processes.
Ormazabal provides DSOs the knowledge, technology and expertise to ensure profitability.
• MV/LV transformer substation automation can be very profitable for DSOs
• But rigorous analysis and simulation is key to grant profitability
• Smart MV/LV transformer substations are key elements in this process providing significant
benefits to the power ecosystem:
• enhance distribution operation and maintenence
• enable preventive and predictive maintenance
• reduce operation and maintenance costs
• improve fault management process
• improve reliability of supply: less frequent and briefer interruptions
• However, automation requires a strong investment for DSOs.
