Disclosed in the present disclosure are a direct current power distribution method, a direct current power distribution device and a direct current power distribution system. The method includes: determining working modes of a direct current power distribution system, correspondingly obtaining, under different working modes, working parameters of the direct current power distribution system, and regulating operation of the direct current power distribution system according to the working parameters to achieve an electric energy balance of a power consumption side, a power generation side of a power grid, and an energy storage side. According to the embodiments of the present disclosure, by the regulating of the direct current power distribution system, an electric energy balance among the power consumption side, the power generation side of the power grid, and the energy storage side is achieved.

Electricity power storage and distribution method, device and system

An energy Internet system, an energy routing conversion device, and an energy control method, relating to a field of energy information. An alternating-current (AC) side energy routing conversion device of the energy Internet system includes a plurality of first route ports, and a direct-current (DC) side energy routing conversion device includes a plurality of second route ports, where each second route port is connected to a corresponding first route port by means of a corresponding DC busbar. A plurality of energy devices are connected to a DC busbar by means of corresponding first AC/DC converters or first DC converters. The AC side energy routing conversion device and the DC side energy routing conversion device collect energy information of the energy devices and adjust energy of the energy devices on a basis of energy balance constraint conditions.

Energy-internet system, energy routing conversion device, and energy control method

A photovoltaic support includes a first vertical upright column () and a second vertical upright column () on a foundation, and a beam () respectively hinged with a first end of the first vertical upright column () and a first end of the second vertical upright column (). The photovoltaic support further includes a first movable connecting piece () provided on the foundation and connected with a second end of the first vertical upright column ().
