Mathematical model for calculation of complex (production/transmission) electric power system reliability

Analysis of electric power system reliability presented in this paper, refers to complex (composite) systems. General issue of assessment of complex electric power system reliability is how to implement and solve mathematical system equivalents and their possible states, taking into account as many possible effects, impacts and conditions of their real functions. Number of possible states of the system in real conditions can be very big, so it is extremely difficult to explore all cases of assessing the reliability of such systems. In this paper, the methods of determining possible states of the system, as well as the methods of determining system deficit, are presented and analysed. For calculations of electric power system reliability, in order to carry out a complete analysis and calculation of characteristic system reliability parameters, it is necessary to determine deficit of electricity. The paper also presents the concrete results obtained using the developed mathematical model and software program developed on its basis.
