The problem of improving power quality (PQ) in the integrated power grid of Russia is an urgent task. The article analyzes the number of power consumers’ calls to Kromskiye District Power Networks “Orelenergo”, a branch of the PJSC “IDGC of the Center” for the issue that power quality indices go beyond the standards established in the regulations. The most common complaints of power consumers are low voltage, high voltage, voltage fluctuations. This is primarily due to physical and obsolete depreciation of the main power grid equipment of the power supply organization, disinterest of consumers and the power supply organization in maintaining power quality at the level of regulations, as well as the lack of power supply or-ganization’s software products that allow real-time voltage loss calculations and offer measures to improve the power quality. The presented algorithm, based on calculations of voltage losses, suggests measures to improve the power quality. The application of the proposed algorithm of the program will allow to increase PQ by means of timely determination of voltage losses.
