Abstract Optimal power flow (OPF) has been used for energy dispatching in active distribution networks. To satisfy constraints fully and achieve strict operational bounds under the uncertainties from loads and sources, this paper derives an interval

The modular multilevel converter (MMC), as a new type of voltage source converter, is increasingly used because it is a distributed storage system. There are many advantages of using the topological structure of the MMC on a unified power quality con

For a high penetration level of distributed energy resources (DERs) in the grid, virtual synchronous generator (VSG) control is applied to the power electronic converters to mimic the rotating mass and damping property of a conventional synchronous g

There exists serious frequency instability in the UHVDC islanded operation system consisting of a large capacity UHVDC and its corresponding power source with hydraulic power generators. Ultralowfrequency oscillation (ULFO) is one of the frequency in

The three-stage modular solid-state transformer (SST) is a typical SST with a non-trivial start-up process. Specifically, special controls must be used to reduce the inrush current in the DC/DC stage during the start-up process of these SSTs. For the

In this study, an interval arithmetic-based method has been proposed for contingency analysis of line outage in DC distribution networks. This method incorporates the uncertainties in source/load which become considerable in the system with increasin

Quantitatively assessing the impact of uncertainties on node voltage in a distribution network is an important issue. This paper proposes a new model to analyze the uncertainty level of voltage from the perspective of the linear quantitative descript
