The voltage control is a challenging task in active distribution networks, due to the increasing penetration of distributed energy resources (DERs). Voltage regulation devices (VRDs) can suffer the presence of DERs due to reverse power flows along feeders. A previous Jacobian-based method for sensitivity analysis of radial distribution system, for both DERs and VRDs, is extended in terms of accuracy. The present paper analyzes firstly the actions of different types of VRDs together with DERs in a large 237-nodes LV distribution network; then, the effects of sensitivity matrices and initial operating conditions on the linear method (LM) accuracy are evaluated. Numerical results show the great accuracy of the LM.

Abstract
The voltage control is a challenging task in active distribution networks, due to the increasing penetration of distributed energy resources (DERs). Voltage regulation devices (VRDs) can suffer the presence of DERs due to reverse power flows along feeders. A previous Jacobian-based method for sensitivity analysis of radial distribution system, for both DERs and VRDs, is extended in terms of accuracy. The present paper analyzes firstly the actions of different types of VRDs together with DERs in a large 237-nodes LV distribution network; then, the effects of sensitivity matrices and initial operating conditions on the linear method (LM) accuracy are evaluated. Numerical results show the great accuracy of the LM.| File | Dimensione | Formato | |
