Title:
ENERGY ROUTING CONTROL METHOD AND APPARATUS, AND ENERGY ROUTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/000580
Kind Code:
A1
Abstract:
The present application provides an energy routing control method and apparatus, and an energy routing system. The method comprises: acquiring a bus voltage feedback value of a direct current (DC) bus, and determining, on the basis of the bus voltage feedback value, an amplitude limiting coefficient corresponding to an external DC source and a first current given value corresponding to an external energy storage unit; performing amplitude limiting on a target current given value on the basis of the amplitude limiting coefficient to obtain an amplitude-limited current given value, and controlling a first DC/DC conversion unit on the basis of the amplitude-limited current given value; and determining, on the basis of the first current given value and a second current given value, a current given value corresponding to the external energy storage unit, and controlling a bidirectional DC/DC conversion unit on the basis of the current given value corresponding to the external energy storage unit. The present application can effectively ensure the energy balance of energy routing.
