The use of energy storage systems is widely recognized as a key tool to create a more resilient energy infrastructure. At the same time, new technologies such as soft-open points and on-load tap changers are deserving growing attention for their potential applications in smart grids. In this paper we consider the coordinated use of on-load tap changer and energy storage systems for voltage support in distribution networks. We first formulate the optimal control problem over a given time horizon as a multi-period optimal power flow. To cope with uncertainties such as inaccurate forecasts, the optimal control problem is then inserted into a receding horizon scheme. The proposed approach requires very limited information to predict possible voltage problems and counteract them in advance. The control algorithm is tested on real data from a low voltage network featuring over- and undervoltages in the absence of voltage control. The obtained results show that the coordinated use of on-load tap changer and storage devices allows one to dramatically reduce the size of the installed storage units required to alleviate voltage issues.

Abstract

The use of energy storage systems is widely recognized as a key tool to create a more resilient energy infrastructure. At the same time, new technologies such as soft-open points and on-load tap changers are deserving growing attention for their potential applications in smart grids. In this paper we consider the coordinated use of on-load tap changer and energy storage systems for voltage support in distribution networks. We first formulate the optimal control problem over a given time horizon as a multi-period optimal power flow. To cope with uncertainties such as inaccurate forecasts, the optimal control problem is then inserted into a receding horizon scheme. The proposed approach requires very limited information to predict possible voltage problems and counteract them in advance. The control algorithm is tested on real data from a low voltage network featuring over- and undervoltages in the absence of voltage control. The obtained results show that the coordinated use of on-load tap changer and storage devices allows one to dramatically reduce the size of the installed storage units required to alleviate voltage issues.
