Method and system for hot-swap power balance control in energy router

Abstract

The embodiment of the invention provides a hot plug power balance control method and system in an energy router. The method includes the following steps of: when detecting that any device in the devices corresponding to each interface of the energy router performs hot plug action, identifying an access device in the devices corresponding to each interface, and obtaining the device number of each access device; taking the access devices as a device combination, acquiring the combination number of the device combination in a preset database according to the device number of each access device inthe device combination, and obtaining a corresponding power balance reserve strategy according to the combination number of the device combination; and performing power rough adjustment on each access device in the energy router according to the power balance reserve strategy, and then accurately adjusting the power in the energy router by adjusting an energy storage converter to ensure that theenergy router reaches an optimal power balance state. The power balance of the device in the energy router after hot plugging is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of energy internet, and more particularly, to a method and system for controlling hot-plug power balance in an energy router. Background technique [0002] Hot swapping of power equipment will impact the power balance of the power grid, causing the voltage to drop or suddenly rise. Once the load is exceeded, it will cause network failures. Generally speaking, when the rated power of the connected power device or the ratio of the working power to the instantaneous power of the grid is too large, the hot swap of the power device cannot be supported. The number of connected devices of an energy router is adjustable, and the ratio of device power to router operating power is not fixed. Hot-swap capability has become an important feature of routers. [0003] Therefore, there is an urgent need to provide a hot-plug power balance control method in an energy router. SUMMARY OF THE INVENTION ...
