This document discusses self-healing in smart grids. It defines self-healing as a smart grid's ability to quickly detect and isolate faults and reconfigure itself to restore normal operations. The document outlines the components of a smart grid that enable self-healing, including sensors, communication infrastructure, control algorithms, and actuators. It also describes the goals of a self-healing system as being reliable, fault-tolerant, and resilient. Tools that can help achieve self-healing are discussed, such as software agents, synchronized phasor measurement units, and information communication technology. Self-healing is explored at the levels of transmission grids, distribution grids, and microgrids.

HEALING
SYSTEM
GOALS
Reliable systems
•Quick and accurate
analysis of faults
•protect the system
from harmful
effects
Fault-tolerant
systems:
•When a fault occur
the system
performance is not
affected.
•Assuring the
continuity of
service under any
conditions.
Resilient system
•Minimization of the
service's self-
renewal period
•Reconfigure to cope
with disturbances.

8. TRANSMISSION
GRID:
• PMU along with GPS
• FCC when DGs integration
• In HVDC Transmission use of CBDISTRIBUTION
GRID:
• Overcurrent relay
• wireless token ring protocol
(WTRP)
• islanding when the power system
faces a crisis situation.
MICROGRIDS:
• group of localized generators,
storage devices, and loads
• ability of a SG to switch the
microgrid from/to the islanding
mode

9. TOOLS FOR
SELF-
HEALING
GRIDS
Software agents
•Grid Component Agents
•Distributed Resource
Agents
•End-User Agents
•Failure Control Agents
•Data Analyse Agents
•Graphical Visualizations
Agents
Synchronized phase
measurement unit
•Synchronized PMU is a
digital device that
measures the phasor
value at a time tag, the
time tag is referenced at
multiples of the power
system rated frequency
Information
communication technology
(ICT)
•collecting and exchanging
information, transferring
results, executing
decisions, and monitoring
real-time device states in
all power grid sectors are
the responsibility of the
smart communications
subsystem
