Direct-current power supply method and device, direct-current power grid system, storage medium and product

Abstract

The invention relates to a direct-current power supply method and device, a direct-current power grid system, a storage medium and a product. The method comprises the following steps: receiving a power supply instruction of a user in a future time period sent by a server; monitoring the power generation and utilization state of at least one electric device and the real-time power utilization demand of the user; according to the power supply instruction, the power generation and utilization state and the real-time power utilization demand, determining a power supply strategy corresponding to the power utilization equipment and the user; controlling the electric equipment and the user to execute the power supply strategy through a direct current bus; the power supply instruction is generated by the server according to a predicted power consumption demand of the user in a future time period, and the predicted power consumption demand is related to historical power consumption data of the user in a historical time period. By adopting the method, the power supply stability of the commercial power grid system can be improved.

Description

technical field [0001] The present application relates to the technical field of power grid power supply, and in particular, to a DC power supply method, a device, a DC power grid system, a storage medium and a product. Background technique [0002] With the continuous development of new energy technology, more and more electric energy is generated by new energy, which makes the electric energy used by users change from a single mains power to a variety of electric energy sources, that is, a large number of new energy sources have flooded into the modern power grid system. The energy generation system provides electricity for users and facilitates users to use electricity. [0003] However, as a large number of new energy power generation systems are connected to the power grid system, the power generated by the power grid system also becomes very volatile. In this case, if the load does not consume the power generated by the power grid system in time, the It will cause the...

Problems solved by technology

[0003] However, as a large number of new energy power generation systems are connected to the grid system, the electric energy generated by the grid system becomes very volatile. In this case, if the load end does not consume the electric energy generated by the grid system in time, It will cause a waste of power generation in the power grid system, and when the new energy power generation system cannot generate power due to conditional constraints, the power supply capacity of the power grid system may not be able to meet the electricity demand
