Methodology for Calculating Indicators of Reliability of Power Supply, Taking Into Account Seasonality

It was revealed that emergency and planned outages in electrical networks are seasonal in nature by months of the year and time of day. Information about the methods for calculating the indicators of reliability of power supply to rural consumers is given and their analysis is performed. It is shown that the existing methods do not allow for a differentiated calculation of reliability indicators depending on the season of the year and the time of day. A methodology has been developed for calculating these indicators, taking into account seasonality by months and time of day, which makes it possible to obtain the probability of failure-free operation for emergency and planned outages, taking into account the corresponding seasonality coefficients.
