Abstract
A method for controlling a microgrid of a hydrometallurgical plant based on an energy storage frequency converter includes: controlling the opening and closing of a first circuit breaker and a second circuit breaker based on frequency change data of an AC bus in a plant microgrid. The energy storage frequency converter includes an energy storage unit, a first AC-DC converter, and an inverter. An input end of the first AC-DC converter is connected to an external power grid through an AC bus, and a first circuit breaker is provided between the first AC-DC converter and the external power grid. An input end of the inverter is connected to an output end of the first AC-DC converter, and an output end is connected to a variable frequency motor. The energy storage unit is connected between the output end of the first AC-DC converter.
