Abstract
Electrical power system (EPS) reliability indices (RI) are calculated at both the
operating and planning stages of power system operation. RI calculation is the
key concern for power reserve estimating and dispatching, validating the new
generation capacity and tie line installations, basic facility maintenance planning,
selecting distribution substation key diagrams and local power system
connecting diagrams and specifying the energy and power charges. The primary
barrier to fast RI calculation is a meshed and hierarchical structure of a power
system, the analysis of which is more of a challenge for an engineer.
Additionally, there are a number of issues concerning the probabilistic nature of
RI. This paper presents novel mathematical algorithms that have been developed
at the department of automated power systems (DAPS) of the Ural Federal
University.
Keywords: reliability indices, power system security, power system adequacy,
structural reliability, simultaneous failures, stochastic network reduction,
Monte-Carlo Simulation, n-1 criterion.
