FIELD: electrical engineering.;SUBSTANCE: by way of preliminary analysis, a complex power pool grid is split into subsystems with minimum mutual impact. For each subsystem being controlled, based on the assumed splitting, one forms databases of sensibility factors and maximally allowed active power flows through links for different types of topology and accidental agitations. All the load lines and nodes of each subsystem being controlled are equipped with link agents and load agents. When any link is overloaded within the subsystem being controlled, such link agent, proceeding from information on the grid current topology and by way of linear optimisation tasks solution and by way of exchange of massages between link agents and load agents, calculates and implements the optimal control action vector. The algorithm keeps being executed until elimination of overloads with all the links within the subsystem being controlled or until any optimisation task being solved within the automation means operation cycle has a solution.;EFFECT: reliability improvement.;2 dwg
