The paper is aimed at an investigation of the features

of a tubular-linear synchronous quasi-Halbach machine (T-LSM)

where the radially-magnetized PMs are substituted by four equal

segments with parallel magnetization. This substitution is done

in an attempt to improve the machine cost-effectiveness which

makes it a viable candidate to equip free-piston engine-based

series hybrid propulsion systems. The study is initiated by an

analytical formulation of the air gap flux density considering (i)

The paper is aimed at a class of fractionalslot

permanentmagnet synchronousmachines (FSPMSMs)

equipped with phases made up of one coil parallel

branches, with emphasis on their potential to reject the

harmonic currents circulating in the loops created by the

parallel branches. Following the identification and topological

characterization of this class of machines in Part 1,

the star of slots approach is extended to the analysis of

the back-EMF harmonic content. This makes it possible the

Extracting the boundaries of Photovoltaic (PV) plants is essential in the process of aerial inspection and autonomous monitoring by aerial robots. This method provides a clear delineation of the utility-scale PV plants’ boundaries for PV developers, Operation and Maintenance (O&M) service providers for use in aerial photogrammetry, flight mapping, and path planning during the autonomous monitoring of PV plants.

The paper is aimed at an investigation of the effects of the mover eccentricity on the PM eddy current loss of tubular-linear synchronous machines (T-LSMs) equipped with quasi-Halbach magnetized PMs. The study is initiated by an analytical prediction of the no-load spatial repartition of the flux density taking into account the non-coaxiality of the mover and stator, and its validation by a 3D finite element analysis (FEA). Then a special attention is paid to an analytical formulation of the PM eddy current loss in presence of eccentricity.

The purpose of distribution network reconfiguration (DNR) is to determine the optimal topology of an electricity distribution network, which is an efficient measure to reduce network power losses. Electricity load demand and photovoltaic (PV) output are uncertain and vary with time of day, and will affect the optimal network topology. Single-hour deterministic DNR is incapable of handling this uncertainty and variability. Therefore, this paper proposes to solve a multi-hour stochastic DNR (SDNR).
