High Voltage Direct Current (HVDC) lines and grids interconnect AC grids to increase reliability, facilitate integration of electricity markets and connect offshore wind generation. To address the growing uncertainty in the operation of such systems and fully utilize HVDC control capabilities, this work proposes a semidefinite relaxation of a chance constrained AC optimal power flow (OPF) for i...

The paper presents a method for the co-optimization of energy storage systems allocation and line reinforcement in active distribution networks. objective is to guarantee capability an network follow dispatch plan by appropriately coping with high uncertainties loads stochastic renewable generation while ensuring secure operation grid minimizing power losses. proposed formulation relies on modi...

The existing research on market price-affecting agents, i.e. price makers, neglects or simplifies the nature of AC power flows in system as it predominantly relies DC flows. This paper proposes a novel bilevel formulation based smoothing technique, where any strategic player can be modelled upper level, while clearing problem lower level uses convex quadratic transmission optimal flow (AC OPF),...

Smart Grid schemes in which multiple network elements and participants are managed for the benefit of the distribution network (e.g., energy loss reduction, restoration, etc.) require sophisticated algorithms to control them in the most suitable manner while catering for network constraints. Such a complex decision making process can be solved by tailoring the AC Optimal Power Flow (OPF) proble...

The increasing application of voltage source converter (VSC) based high direct current (VSC-HVDC) technology in power grids has raised the importance incorporating DC and converters into existing transmission network. This poses significant challenges dealing with resulting optimal flow (OPF) problem. In this paper, a recently proposed nonconvex distributed optimization algorithm—Augmented Lagr...
