The proper placement of distributed generations, especially wind turbines, is a challenging issue in distribution networks. In this regard, this paper employs the fuzzy adaptive modified particle swarm optimization (FAMPSO) to determine the locations of wind turbines in a radial distribution network by considering power losses, operation cost reduction and voltage stability improvement as the objective...
This paper presents an optimal design for simultaneously locating unified power flow controller (UPFC) and power system stabilizer (PSS). The parameters of their controllers are also tuned coordinately to enhance the power system stability. A mixed integer nonlinear problem is obtained for the design procedure due to the characteristics of selected objective functions. A new population-based meta-heuristic...
This paper presents a new method for coordinately tuning the parameters of UPFC controller and power system stabilizer (PSS) as well as determining the PSS location to enhance the stability of power system by using a new hybrid particle swarm optimization based co-evolutionary cultural algorithm, so called culture-PSO-co evolutionary (CPCE). Nonlinear simulations are implemented on the IEEE 39-bus...
This paper presents a kinematically redundant four actuated-joint degrees of freedom planar parallel manipulator. The workspace of the proposed manipulator is larger than of the non-redundant counterpart and vast majority of its singularities can be avoided by using kinematic redundancy. First, the forward and inverse displacement problems of the manipulator are solved and its workspace is obtained...
