We consider the problem of realigning a space telescope from one observation target to next in presence prohibited directions. More specifically, we want steer – modelled as gyrostat an initial attitude at rest final within fixed time interval. During motion, line sight must be kept away forbidden directions towards bright objects like sun, moon or earth due power thermal requirements. The kine...

This paper presents an effective evolutionary method for solve economic dispatch (ED) with units having prohibited operating zones. ED has been widely used in power system operation and planning for determination of electricity prices. ED problem is a non smooth problem when valve point effects of generation units are considered. With addition the valve point effect and prohibited zones in ED p...

Economic dispatch (ED) problem is a nonlinear and non-smooth optimization problem when valvepoint effects, multi-fuel effects and prohibited operating zones (POZs) have been considered. This paper presents an efficient evolutionary method for a constrained ED problem using the new adaptive particle swarm optimization (NAPSO) algorithm. The original PSO has difficulties in premature convergence,...
