Predetermined by the need to increase effectiveness of electric power supply and electric power consumption, the interconnected problems of effectiveness of these processes were explored. The object of present study is effectiveness of operation of electric power systems and the subject of the study is the processes to increase their effectiveness. The problems are caused by energy-consuming technologies, unstable consumption of electricity and out-dated organization. On the one hand, it is the variable system of electric power consumption, on the other hand, the unstable system of electric power supply. It was established in the work that these systems could be balanced by their constant optimization. All operative factors of influence are established for this. Based on this, the processes of electric power consumption and supply are optimized with the help of the diagram of cause-effect interrelations. All factors, which influence effectiveness of electric power consumption and electric power supply, are represented by the Ishikawa Kaoru diagram and are divided into four groups: organizational, technical, technological and economic with their specific definition. It was followed by an analysis of their influence with separating 7–9 basic factors in each group. The establishment of the optimum variant of EPS and EPC is classically reduced to determining characteristic of distributive function, strategy and modes at minimization of effectiveness indicators. It is simpler to establish the optimum structure of electric power supply and electric power consumption, using, to describe them, directed graphs, the vertices of which correspond to the elements of the structure, and arcs correspond to relationships between them. For further mathematical processing, this directed graph is described by the system of matrix equations and the task is reduced to the search for minimum or maximum paths in the directed graph.References
