This article presents an agent-based model algorithm for voltage coordinated control using reactive capacity sources in electrical power distribution networks of railways. Voltage control in an electrical network is coordinately implemented by the managing system between all local regulators within the controlled zone. We present an approach to coordinate the work of local regulators basing on auction-type ranking of their possibilities for achievement the global control purpose. During operational voltage control in electrical network we proposed to use linearization of the control task, since the relationship between relative power gains and loads of individual nodes in the form of sensitivity matrix (Jacobi) is almost linear. We performed simulation and mathematical modeling of the proposed algorithm in the distribution electrical network of railways and present the obtained results.
