FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to a method for controlling the modes of an electric power system. According to the method, power cluster network control centers are equipped with devices for collecting and storing operational data coming from substations from automated process control systems, and additional computing devices (ACD) with multi-agent control systems. Through the ACD, constraints from the ACD of adjacent energy clusters are detected to maintain the levels of boundary stresses and active power flows. Taking into account the measurement data collected in the ACD and the obtained constraints, working control algorithms are implemented with local optimization of the electrical power system modes in terms of voltage and reactive power. The control of the electric power system’s operation mode is carried out by all ACDs in parallel mode starting with each ACD optimizing the mode inside its energy cluster. From each ACD sends messages to the ACD of adjacent power clusters with the values of voltage and parameters of active power flows, which were obtained during the calculation of the optimal mode for their power cluster, via the computer network. Each ACD receives messages from the ACD of adjacent power clusters with restrictions imposed on the voltage and parameters of the active power flow and presented to each ACD in the form of a target loss function that ensures the maintenance of the levels of boundary stresses and active power flows. Taking into account these restrictions, as well as the criteria determined by business interests, they adjust the optimization of the regime of their energy cluster.

EFFECT: electric power systems working mode is optimized.
