Title:
METHOD AND APPARATUS FOR OPTIMIZING OPERATION OF TRANSFORMER SUBSTATION
Document Type and Number:
WIPO Patent Application WO/2023/004804
Kind Code:
A1
Abstract:
The present invention provides a method for optimizing the operation of a transformer substation. The transformer substation comprises a plurality of transformers, and the transformers are connected or disconnected by means of switches. The optimization method comprises: acquiring the current loads of transformers among a plurality of transformers, and according to the current loads, predicting predicted loads of the respective transformers under various possible operation modes in a plurality of time periods; calculating transformer costs of the respective transformers in the plurality of time periods according to the predicted loads of the respective transformers, the transformer costs comprising transformer losses and transformer operation costs; calculating switch costs in the plurality of time periods according to purchase costs and the service life of the switches corresponding to the respective transformers; and calculating a total cost in a total time period according to the transformer costs and the switch costs, optimizing the total cost to obtain optimization parameters, and operating a transformer substation according to the optimization parameters, the total time period consisting of the plurality of time periods.
