Abstract

The invention relates to a constant-power flexible operation control method, system and device and a storage medium, and the method comprises the following steps of analyzing the type of a source load with the load regulation and control capability in a power distribution system, and determining a power relation in the power distribution system; and on the basis of a preset load adjustment rule and the power relation in the power distribution system, controlling the charging and discharging states of each source load, so that the stable constant-power flexible operation of the power distribution system is realized. According to the present invention, on the basis of giving full play to the distributed photovoltaic power generation capacity, through the coordinated control over an energy storage device and a controllable load, the power purchase cost in an area is reduced, the energy conservation and emission reduction of a building are achieved, the construction investment cost is reduced, and the clean energy consumption capacity is improved. The method can be widely applied to the field of building power distribution system construction.

Description

technical field [0001] The invention relates to the application field of power electronics technology, in particular to the field of low-voltage DC buildings based on optical storage direct flexibility, especially a constant power flexible operation control method, system, equipment and storage medium based on the coordination of optical, storage, and new energy vehicles. Background technique [0002] For the power system, in order to adapt to the characteristics of the high proportion of clean energy penetration in buildings and the differentiated power demand of multiple users under the "dual carbon" goal, building a new generation of flexible, efficient, safe and reliable building power distribution system has become a distribution system. One of the key points of the future development of the network field. Compared with the existing AC system, the building power distribution system mostly adopts the DC networking form, which is easier to realize the flexible access of d...
