This paper is devoted to optimal sizing. As a model example we consider the minimization of the mass of the frame of an injection moulding machine. The deformation of the frame is described by a generalized plane stress state with an elasticity modulus scaled by the thickness. This constrained nonlinear optimization problem is solved by sequential quadratic programming (SQP) which requires grad...

natural frequency is one of the parameters that represent useful information about the dynamic behavior of structures. controlling this parameter can decrease the probability of damage under dynamic loading. weight optimization on layout and sizing with frequency constraints is a well known problem because of its highly non-linear behavior. improved ray optimization (iro) algorithm is utilized ...

For remote places having less-strong wind, single resources based renewable energy system (RES) with battery storage can sustainably and economically generate electrical energy. There is hardly any literature on optimal sizing of such RES for very low load demand situation. The objective of this study is to techno-economically optimize the system design of a Photovoltaic (PV)-battery storage RE...

In this paper, we develop a set of delay estimation models with consideration of various interconnect optimization techniques, including optimal wire-sizing (OWS), simultaneous driver and wire sizing (SDWS), and simultaneous buuer insertion/sizing and wire sizing (BISWS). These models have been tested on a wide range of parameters and shown to have about 90% accuracy on average compared with ru...

The problem of the optimal siting and sizing photovoltaic (PV) sources in grid connected distribution networks is addressed this study with a master–slave optimization approach. In master stage, discrete–continuous version Chu Beasley genetic algorithm (DCCBGA) employed, which defines locations sizes for PV sources. slave successive approximation method used to evaluate fitness function value e...

This research deals with the problem regarding optimal siting and sizing of distribution static compensators (D-STATCOMs) via application a master–slave optimization technique. The master stage determines nodes where D-STATCOMs must be located their nominal rates by applying generalized normal optimizer (GNDO) discrete–continuous codification. In slave stage, successive approximations power flo...

this paper presents a probabilistic confidence-interval based method for optimal placement of shunt capacitors in distribution networks by considering probabilistic characteristics of loads. the main objective function are reducing loss and improving the voltage profile. backward forward sweep method has been employed to obtain the power flow results in distribution system. in addition, integer...
