Appropriate size and location of distributed generation (DG) play a significant role in minimizing power losses distribution systems. This paper represents techniques to minimize feeder by optimizing DG model terms size, operating point DG. Sensitivity analysis for has been performed. The proposed sensitivity indices can indicate the changes with respect current injection. have developed considering load characteristics representing loads constant impedance models, separately. optimal be...

In a distribution system, it is essential to maintain the voltage variation within specified limit for satisfactory operation of connected customers' equipment. Normally, this goal achieved by controlling compensating devices, such as load tap changing transformers, shunt capacitors, series reactors and static VAr compensators. However, technical regulatory developments are encouraging greater number small generator units, known distributed generation (DG), has potential significantly affect...

This paper aims to study a specific kind of parallel robot: Spherical Parallel Manipulators (SPM) that are capable unlimited rolling. A focus is made on the kinematics such mechanisms, especially taking into account uncertainties (e.g. conception & fabrication parameters, measures) and their propagations. Such considerations crucial if we want control our robot correctly without any undesirable behavior in its workspace effects singularities). In this paper, will consider two different...

This article discusses the implementation of a software joint velocity limitation dedicated to Spherical Parallel Manipulator (SPM) with coaxial input shafts (CoSPM) using speed control loop. Such an algorithm takes as current positions well reference velocities computed by controller and limit latter in order avoid any known singular configuration. into account workspace properties mechanism physical characteristics its actuators. In particular, one advantage coaxiality CoSPM resulting...

This article dives into the use of a 3-RRR Spherical Parallel Manipulator (SPM) for purpose inertial Line Of Sight (LOS) stabilization. Such parallel robot provides three Degrees Freedom (DOF) in orientation and is studied from kinematic point view. In particular, one guarantees that singular loci (with resulting numerical instabilities inappropriate behavior mechanism) are far away prescribed workspace. Once kinematics device certified, control strategy needs to be implemented order...
