3.5.1. Introduction
The energy system resilience is the ability of an energy system to provide
and maintain an acceptable level of service in the face of various challenges to
normal operation.
Resilience can be defined in two ways. The first is a measure of the
magnitude of disturbance that can be absorbed before the system changes its
structure by changing the variables and processes that control behavior. The
second, a more traditional meaning, is as a measure of resistance due to
disturbance and the time of return to the equilibrium state of the system.
―Resilience aim is to provide acceptable service to applications: ability for
users and applications to access information when needed, e.g.: distributed
database access, sensor monitoring, situational awareness and operation of
distributed processing and networked storage, e.g.: ability for distributed
processes to communicate with one another, ability for processes to read and
write networked storage. Note that resilience is a superset of survivability‖.[1].
In the understanding of sustainability development the major precondition
is to highlight the role of the material and energy consumption as a source of
unsustainable pattern of the development. The need to balance the social,
economic and environmental sustainability is the goal of energy accessibility,
availability and acceptability [2] .
The energy sustainability keys are: energy diversity and energy efficiency,
energy infrastructure investment, cost-reflective prices and market-sensitive
intervention, supply reliability, regional integration of the energy system,
market-based
climate
change
responses,
technological
innovation
and
development and public understanding and trust [3].
Resilience provides a new framework for analyzing economic, ecological,
technological and social systems in a changing world facing many
uncertainties and challenges. It represents an area of explorative research
under rapid development with major policy implications for sustainable
development.
