Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] figure 1 It is a schematic diagram of the composition and structure of an energy router according to an embodiment of the present invention. Such as figure 1 As shown, the energy router provided by the present invention may include: a control unit, an electric power conversion stage, and an energy storage device. Those skilled in the art can understand that the single battery shown in the figure can be a battery composed of several small rechargeable battery cells, for example, it can be a lead-acid battery or a lithium battery (48V100Ah). Even so, the voltage of the battery composed of rechargeable battery cells connected in series is also relatively ...

Abstract

The invention discloses an energy router and an energy storage system based on the energy router. The energy router comprises a control unit, an electric energy power conversion stage, and an energy storage device, wherein the control unit is configured to respond to an energy request to send an electric energy transmission instruction to the electric energy power conversion stage; and the electric energy power conversion stage is configured to respond to the electric energy transmission instruction to change the electric energy transmission state of the energy storage device. Through the above technical scheme, the provided energy router can decide the electric energy transmission state according to the energy request, and scheduling and management on energy of the energy storage device can be realized.

Description

technical field [0001] The invention relates to the field of microgrid energy storage, in particular to an energy router and an energy storage system based on the energy router. Background technique [0002] Distributed power generation is a new type of power supply mode that has developed rapidly in recent years. Most of the electricity generated by renewable energy can be distributed nearby to reduce environmental pollution. It has received more and more attention. Distributed power generation can be Digest energy efficiently, save investment and operating costs of power transmission and transformation, reduce line losses of centralized power transmission, complement each other with large power grid power supply, reduce power grid capacity, improve peak and valley performance of power grid, improve power supply reliability, and reduce environmental pollution, etc. The advantages have received extensive attention, especially photovoltaic and wind power systems have been dev...
