Abstract
Abstract. The research focuses on addressing the challenges of evaluating the effectiveness of modern power systems in countries with different configurations. Given the growing interest of con-sumers in the impact on the electricity supply schedule, the research is divided into two main parts. Firstly, a model has been developed to assess the operational efficiency of the power system. Secondly, a method for analyzing the efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The presented model takes into account energy system characteristics such as the probability of network failure, normalized frequency of electricity, and the volume of consumed and supplied electrical energy. It is expected that this model will provide a more accurate assessment of the efficiency of the energy system under normal operating conditions. Additionally, a method for analyzing the operational efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The uniqueness of this method lies in the introduction of a new comprehensive indicator of energy system efficiency, deter-mined by the convolution method of partial indicators, namely: the volume of electricity supply, supply quali-ty, and electricity supply efficiency. The reliability of the model is confirmed by calculations of the daily schedule of supply and load. Keywords: electric power system, electricity supply efficiency, evaluation of power supply system effi-ciency, electricity indicators, load schedule, consumer management, electricity supply quality.
