Abstract

Embodiments of the present invention relate to the technical field of power systems, in particular to a transformer load rate control apparatus and method. The apparatus includes a centralized controlsystem and a plurality of energy storage systems, each energy storage system is installed on the low-voltage outlet side of the corresponding transformer, each energy storage system is communicatively connected with a centralized control system, the centralized control system is used for obtaining the real-time total load rate and the maximum load rate of the user side, A real-time total load rate and a maximum load rate are compared to obtain a comparison result, A charge / discharge instruction is generated according to the comparison result and sent to each energy storage system, each energystorage system is configured to receive a charge / discharge instruction, charge and discharge according to the charge and discharge instruction, so as to realize the adjustment of the real-time load rate of the transformers corresponding to each energy storage system, the centralized control system is used for obtaining the real-time remaining power of each energy storage system, and the corresponding energy storage system is controlled to stop charging and discharging according to the change of the real-time remaining power, so as to realize the efficient control of the load rate of the transformers.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power systems, and in particular, relate to a transformer load rate control device and method. Background technique [0002] With the rapid increase of loads such as distributed photovoltaics and electric vehicle variable power generation, the amplitude and frequency of power load fluctuations on the user side of the power system are gradually increasing, which brings great challenges to the operation and scheduling of the distribution network. For this reason, the operation scheduling of the distribution network can be realized by adjusting the load rate of each transformer on the user side, but most of the existing methods for adjusting the load rate of the transformer are inefficient. Contents of the invention [0003] In view of this, the present invention provides a transformer load rate control device and method, which can realize high-efficiency control of the transformer lo...
