In this paper, we review the emerging challenges and research opportunities for voltage
control in smart grids. For transmission grids, the voltage control for accommodating wind …

Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

With rapid growth of renewable energy sources (RESs) in modern power systems, the
microgrids (µGs) have become more susceptible to the disturbances (eg large …

The renewable power systems have become more susceptible to the system insecure than
traditional power systems due to reducing of the total inertia and damping properties that …

This paper presents a coordination strategy of Load Frequency Control (LFC) and digital
frequency protection for an islanded microgrid (MG) considering high penetration of …

Due to the increasing penetration of photovoltaic (PV) power systems in active distribution
networks (ADNs), PV power fluctuations may result in significant voltage variations of ADNs …

The higher variability introduced by distributed generation leads to fast changes in the
aggregate load composition, and thus in the power response during voltage variations. The …

This paper describes an approach to estimate the flexibility of an Active Distribution Network
(ADN) to provide ancillary services across voltage levels by the regulation of the power flow …

Nowadays, microgrids are more likely to operate in an isolated state, and it is of outmost
importance to consider various security issues in the management of such systems. This …

The power grid is transforming with large amounts of distributed energy resource (DER)
integration that is impacting the bulk power system planning and operations. Grid regulators …
