Research on Optimization Method for AC Melting of Distribution Network Lines Considering Line Loss
In the current AC icing process of distribution network lines,most of them only consider cost for icing optimization,ignoring some attribute factors,resulting in the maximum icing thickness of the optimized lines still being relatively large.Therefore,a study on the optimization method of AC ice melting for distribution network lines considering line losses is proposed.Considering that line loss and heat generation will suppress the growth of icing,a icing growth model considering line loss is established to reflect the severity of icing on distribution network lines.With the goal of minimizing the operating cost and minimum icing thickness of AC icing,the objective function for optimizing AC icing on transmission lines is defined,and current constraints,voltage constraints,icing start constraints,icing thickness constraints,and icing urgency constraints are proposed.Relying on the taboo search algorithm to solve the optimization objective function,the final AC ice melting optimization decision is generated through global gradual optimization.The analysis results of algorithm examples show that after the implementation of the optimization decision obtained by the proposed method,the maximum thickness of icing on the distribution network lines is only 15.67mm,which meets the requirements for safe operation of the transmission network.
