With the increase of electricity demand and the rapid development of renewable energy
generation, it is becoming more and more important to ensure the safety and stability of …

This paper proposes a unified load flow (LF) model for AC-DC hybrid distribution systems
(DSs). The proposed model can be applied in hybrid DSs with mixed configurations for …

Due to inherent uncertainty and volatility, large-scale wind power integration brings new
challenges to the flexible operation of power systems. It calls for more flexibility not only from …

This paper proposes a multi-option power flow approach for hybrid AC/DC grids. A unified
AC-DC unit is introduced which can be used in two different cases: case a) AC grids with …

A promising configuration for future smart grids is an AC/DC hybrid topology that enables the
integration of AC/DC energy resources and modern loads, thus permitting the consequent …

The proliferation of technologies operating on dc power has motivated the system planners
toward integration of dc and ac grids. The optimal power flow (OPF) analysis is widely used …

This paper presents a detailed analysis of commutation failure, AC/DC power flow, and
voltage stability of multi-infeed high-voltage direct current (HVDC). The use of HVDC power …

The ac-dc distribution systems have recently gained huge popularity due to advancements
in power converters, high penetration of renewable energy resources, and wide usages of …

This paper proposes a new method to solve the multistage security-constrained
transmission expansion planning problem, incorporating lines based on high-voltage …

This paper proposes a novel power flow algorithm for islanded hybrid AC/DC microgrids.
The algorithm is based on a recursive (non-iterative) method called the holomorphic …
