Abstract
In this paper the reliability of networks and especially the
cascading failures are analyzed. As a special type of network
the electric power grid is considered. The network is modeled
(taking into account the nature of electricity networks) using
linear programming dispatch of the generated electricity to
the consumers. The data of the electric power system of
Southeast Europe are used. The reliability of the network is
analyzed using the OPA model which enables cascading
failure analyzes based on probabilistic outages of the
overloaded lines and includes long-term upgrading of the
system in response to the increased electricity demand over
the time. In this paper, the OPA model is extended to include
the minimum generation capacity of each power plant and it
is analyzed how this constraint affects the cascading failures.
The results show that this constraint introduces additional
instability in the system that leads to higher cascading failures
of the power transmission lines
