“…Moreover, the day-ahead forecasting error could go large leading to uncoordinated control in many cases. To address these issues, robust multi-step voltage control mechanisms [42], [43] have been devised to provide reactive power support from VSCs under such scenarios. Basically, these control mechanisms for local reactive power support operate to minimize tap changes of on-load tap changer (OLTC) based on the minimum and maximum voltage setpoints.…”

Grid tied power electronic converters are key enabling technologies for interfacing renewable energy sources, energy storage, electrical vehicles, microgrids and high voltage dc transmission lines with the electrical power grid. As number of power converters in modern grids continually increase, their monitoring and coordinated control in a way to support the grid have become topics of increased practical and research interest. In connection with this, latest standards have also defined mandatory set of control parameters for grid-tied converters, which should be adjustable by a remote entity that sends commands through a communication network. While such remote control capability allows many new control functions in grid tied converters, it also renders them vulnerable to cyber attacks. The aim of this paper is first to shed light on portions of the power converter control systems that are vulnerable to cyber attacks. Next, typical cyber-attacks are overviewed by considering different applications of grid-tied converters. Further, the impact of different types of cyber attacks on grid support functions is studied. Finally, the paper is concluded with summary and recommendation for further research.

“…have been used. A voltage‐control strategy based on multistep MPC was used to adjust the Q(U) characteristics to reduce the number of tap movements of the on‐load tap changer (OLTC) and also reduce the number of voltage fluctuations in [7]. Also, an MPC‐based control strategy was implemented in [8, 9], where the local Q(U) control parameters were tuned and adjusted to deal with voltage violations on the grid.…”

This study seeks to exploit the reactive power capability of inverter-based distributed generation (DG) to solve the voltageregulation challenges associated with weak mediumvoltage distribution networks in developing countries. Voltage-dependent reactive power control, also known as the Q(U) control method, is widely used for voltage regulation. The challenge with this control mode, however, is determining its control parameters, which must be unique for each bus for optimal performance compared with implementing standardised or general parameters. This paper proposes an innovative approach to incorporate an adaptive functionality into the typical Q(U) control to enhance its performance in medium-voltage grids. This concept, when implemented, achieved better performance than that of the Q(U) control with fixed parameters, which was unsatisfactory under certain conditions, and performance comparable to that of the centralised voltage scheme, which relies on communication facilities.

The blossom of renewable energy worldwide and its uncertain nature have driven the need for a more intelligent power system with the deep integration of smart power electronics. The smart inverter is one of the most critical components for the optimal operation of Smart Grid. However, due to the deep information and communication technology (ICT) infrastructure implementation that most inverter-based smart power systems tend to have, they are vulnerable to severe external threats such as cyberattacks by
