Integrated volt/Var control in modern distribution power systems based on support vector machines

摘要

Integrated volt/Var control (IVVC) is an important tool to optimize voltage and VAR resources and improvernenergy efficiency and, therefore, plays an important role to support the smart grid vision. This paper investigates the application of support vector machines (SVMs) to control switched capacitor banks and voltagernregulators of distribution systems in order to minimize system losses and maintain acceptable voltage profile. The objective is to develop an approach that can use voltage/current measurements provided by activernand reactive monitors to IVVC control without the need to perform retraining or repeat optimization simulations. The performance of the SVM scheme for different input selection (i.e., active and reactive powerrnand node voltage) is discussed. Moreover, the generality of the proposed SVM scheme is investigated underrnnoisy environment as well as under network reconfiguration. Studies on a typical distribution system showrnthat the proposed approach has been able to achieve satisfactory results. Copyright © 2016 John Wiley &rnSons, Ltd.
