Problems solved by technology

[0004] However, if the optical stacking transformation is performed on the DC bus side of the computer room, not only the cost of the transformation is high, but also the optical stacking transformation on the DC bus side can only cover the DC equipment on the DC side, and the site power supply needs to have a DC access interface. The DC equipment has a DC coupling point, and during actual installation, the DC equipment in the equipment room needs to be powered off and cut over, and there are potential safety hazards during power off and cutover
However, if the stacking retrofit is carried out on the side of the AC bus, it is usually necessary to configure energy storage equipment that is compatible with photovoltaic modules. ) is too low

Abstract

The system comprises a controller, an alternating current power grid, at least one photovoltaic module, an inverter, an alternating current bus, an alternating current power distribution cabinet, a direct current bus, an alternating current-to-direct current circuit, a direct current-to-direct current circuit and energy storage equipment, the alternating-current power grid is connected with the alternating-current bus; the photovoltaic module is connected with the inverter, the inverter is connected with the alternating-current bus, the alternating-current power distribution cabinet is connected with the alternating-current bus and the alternating-current-to-direct-current circuit, and the alternating-current-to-direct-current circuit is connected with the direct-current bus; the DC bus is connected with the DC-to-DC circuit; the DC-to-DC circuit is connected with the energy storage equipment; the controller is used for adjusting the energy storage device to be in a charging state or a discharging state according to the output total power of the photovoltaic module, the load total power and the load state of the alternating current power grid. By using the optical storage system provided by the invention, on the premise of reducing the optical stacking transformation cost, the difficulty of optical stacking transformation is simplified.

Description

technical field [0001] The present application relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic storage system and a photovoltaic storage scheduling method. Background technique [0002] A server is a high-performance computer that provides various services. It has high reliability, availability, manageability and scalability. The server is usually located in the computer room. In order to ensure that the server can still provide normal power supply under abnormal conditions, it is necessary to perform redundant configuration on the power supply of the server. [0003] In order to redundantly configure the power supply of the server, there is a demand for light stacking transformation in the existing computer room. Among them, the superimposed photovoltaic transformation refers to: superimpose photovoltaic power supply on the basic power supply, install photovoltaic panels that meet the load power demand or exceed the load...
