The Optimal Load Curtailment of Urban Railway Load

Abstract

-To execute load curtailment efficiently for Urban Railway Load, the load patterns of the Urban Railway Load and available amount of load curtailment over the Urban Railway Load are analyzed through comparing the load to the common power loads. In addition, the current policies of the load curtailment for the Urban Railway Load are investigated and the problems of those are presented. Based on the researches, the optimal load curtailment strategies for the Urban Railway Load are proposed to minimize the consumer's utility diminishment and the costs of the use of energies. Finally, the optimal load curtailment strategies are applied to the real Urban Railway Load, the results shows that proposed methods are efficient and cost effective while the amount of load curtailment is minimized.

“…Equation (1) indicates the objective function of optimization and aims to minimize the sum of squares of the total power used in loads in every single hour. AHU n,t and Blower n,t indicate the output of air-conditioning facilities and ventilation facilities, respectively.…”

“…As introducing the concept of the demand response (DR), the behavior of electricity consumers has changed from naively saving electricity to reduce electricity bills, to setting up a cost-saving strategy based on the price of electricity [1][2][3][4].…”
