3.3.1. Introduction

Photo-voltaic power plant is designed to convert solar energy in the
electricity. PV plants are composed of following elements, namely: Solar
collector, DC convertor, Transmission element. Safety of PV plant depend the
potential changes of the behaviors of the plant elements. In order to keep
control of the PV plant it is of great importance to validate potential changes
of the power plant indicators.
Sustainability index of PV plant is defined by the number of indicators
specified to reflect respective quality of the system. Among those indicators
are : Local insulation, Collector conversion efficiency, DC conversion
efficiency , Environment precipitation and Maintenance Cost. The change of
sustainability index is result of the changes of the individual parameters of the
system.
Resilience of the Photo-voltaic power plant is the capacities of the plant to
withstand sudden changes of the indicators. In this analysis we will present
application of the resiliency index to monitor the stability of the PV plant
system. This analysis will be based on the monitoring of following: indicator
changes: Local insulation change, Collector efficiency change, DC conversion
efficiency, Environment precipitation Maintenance change.
