measure of the Resilience Index. In this respect, the sudden change of
indicators is scaled in the single scale, and the time of integration for all
indicators is the same.
The Resilience Index of the power plant under consideration will be
defined under specific constrains, namely, the sudden change of specific
indicators with other indicators being constant.
This approach will give us the possibility to validate the change of
indicators on the safety of the energy system under specific constrain.In the
evaluation of the resilience index for natural gas power plant , it is anticipated
that the sustainability index change is composed of the indicators reflecting
following potential changes : fuel consumption change G, CO

Fuel consumption change is usually result quality of gas, and can
associated with atmospheric air composition. In our evaluation we will assume
the constant gas quality so that fuel consumption change will be attributed
only to combustion process deficiency. The fuel consumption will be
measured amount of gas supplied to the combustion changer divided by power
generation in unit time and will be expressed in kg/kWh. The maximum
change of this indicator is assumed to be xxx kg/kWh.
