Modeling and method for assessing the efficiency of the power system

Abstract

The work is dedicated to addressing the issues related to assessing the efficiency of modern electrical power systems, especially as an increasing number of consumers desire to actively influence the electricity supply schedule, providing conditions to electricity producers. The research can be divided into two main segments: the development of a model for assessing the efficiency of electrical power system operation and the development of a method for analyzing the performance of the energy system, which is based on a model of changes in the quality indicators of the energy system. The proposed model takes into account properties of the energy system such as the probability of uninterrupted network operation, normalized frequency of electrical power, the volume of consumed electrical energy, and the electrical energy supplied by the transmission organization. It is expected that this model will help provide a more accurate assessment of the efficiency of energy system operation under normal operating conditions. Furthermore, a method for analyzing the efficiency of energy system operation has been developed, which is based on a model of changes in the quality indicators of the energy system. A unique feature of this method is the introduction of a new comprehensive indicator of energy system efficiency, which is determined using a convolution method of partial indicators, namely: the volume of electrical energy supply, the quality of electrical energy supply, and the efficiency of electrical energy supply. The reliability of the model was confirmed through the calculation of the daily electric supply and load schedule.
