“…Це дозволяє значно підвищити надійність електропостачання, ефективніше використовувати відновлювані джерела енергії та збільшує маневрові можливості споживачів електроенергії. І тим не менш, щодо питання вирівнювання, не говорячи про бажане маневрування, добовими графіками навантаження підприємств уваги сьогодні приділяється дуже мало [11].…”

The purpose of this paper is to analyze the main reasons for the increase in power fluctuations in electric power grids and to estimate the maneuvering capabilities of electric loads of industrial enterprises. To achieve the goal, the issues of interaction between the general and industrial electric power grids were analyzed. Methodology. general methods of mathematical analysis and computational mathematics were used in solving the tasks. Results. The results of the analysis indicate a significant increase in power fluctuations in the power grids due to the growth of electricity generation by renewable sources that depend on weather conditions and the random nature of the industrial enterprises' consumption operation modes. It is noted that there are many electricity consumers who have the ability to shift or limit the duration of their work during the day. Accordingly, they can help improve the shape of daily load curves by increasing the total electricity consumption during the hours of minimum grid load and limiting its consumption during the hours of maximum load without significantly affecting the technological process of the enterprise. The maneuvering capabilities of electric loads are considered on the example of the repair and mechanical workshop of an industrial enterprise. Electricity consumers are characterized by the duration of operation, the amount of electricity consumed, the duration of operation and pause cycles, and the time intervals when it is not desirable to disconnect the consumer due to limitations of the technological process or its operation mode. Originality. In the paper, for the first time, it is proposed to estimate the maneuvering capabilities of industrial enterprises to level the load curve of power grid by an appropriate coefficient that takes into account the number and specified capabilities of electricity consumers. Practical value. The use of the proposed maneuverability coefficient allows us to estimate the theoretical ability of an enterprise or its subdivision to participate in reducing power fluctuations in power grids, provided that the necessary measures are economically feasible.
