Patent number: 11843249Abstract: A system and method for determining currents for injection into or extraction from a power network are provided. In a method conducted at a point of common coupling to the network, Thévenin parameter data structures for each of a Thévenin voltage, resistance and inductance, are compiled. An offset data structure including offset values is compiled for application to corresponding values of the Thévenin voltage data structure to output an offset Thévenin voltage data structure. Offset values are calculated to satisfy physical constraints associated with the network. An optimal point of common coupling power data structure and the offset Thévenin voltage data structure are used to calculate current components for determining current for injection into or extraction from corresponding lines at the point of common coupling to reduce total electrical transmission losses of the network. The method may use the frequency domain and may include using frequency-dependent Thévenin parameters.Type: GrantFiled: April 3, 2020Date of Patent: December 12, 2023Assignee: University of Cape TownInventors: Charles Trevor Gaunt, Michel Malengret
