Reactive power optimization is a mixed integer nonlinear programming problem where metaheuristics techniques have proven suitable for providing optimal solutions. In this paper, swarm and evolutionary algorithm have been applied for reactive power optimization. The objective of this nonlinear optimization is minimization of system losses and improvement of voltage profiles in a power system. A hybrid...
Research was made on the design scheme and basic algorithm of a kind of voltage-feedback type digital stabilized voltage switching mode power supply combining internal resources of single-chip microcomputer with control technique. Take 110V switching mode power supply by electric locomotive as an example, it adopted advanced sensor in sampling data, applied PID control algorithm to adjust voltage...
