Microgrids of a Hexagonal Configuration with Solid-State Voltage Regulators

Abstract

The article describes approaches to constructing intellectual Microgrid networks with the sources of distributed generation. The application of a formalized topology of a 6–20 kV distribution network in the form of the hexagonal network is proposed. The principles and algorithms of a post-accident reconfiguration of a hexagonal distribution network are considered. The analysis and classification of flow control devices has been carried out. A method for limiting emergency currents in a Microgrid network of the hexagonal configuration using power flow control devices is proposed. The analysis of various emergency operating modes in the Microgrid network with intellectual devices based on the Solid-State Voltage Regulators from the bus-pulse modulation at the network frequency has been carried out.
