However, in practical applications, customers do not know how much data can be set to optimize the control strategy of the gateway, so customers often do not set parameters, and the gateway has been running at the factory default value
The default parameters of the gateway are not combined with the specific actual situation of the station area. The load type and control mode are all based on default experience. When controlling reactive power and voltage (power quality), there is a high probability of miscontrol, control oscillation, and poor control effect. Obvious, even counterproductive, control issues

Description
technical field [0001] The present invention relates to the technical field of edge-cloud collaboration, and in particular to a method and system for cloud-edge collaboration of optical storage charging in a platform area. Background technique [0002] At present, a large number of distributed photovoltaics are connected to low-voltage station areas, and there are problems such as small capacity, large quantity, uneven distribution, and difficult management. In addition, distributed photovoltaics, energy storage, loads, charging piles or topological structures in the user-side power grid are different, so it is impossible to target The operating status of the low-voltage platform area is effectively coordinated and controlled. [0003] The existing coordinated control of optical storage and charging mainly considers local control in the station area, but limited by the computing and storage capabilities of the local terminal (fused terminal), the analysis dimension of local ...
