To reduce losses due to hysteresis, amorphous alloy is used in the magnetic circuit. A seven-phase design is considered, with three independent windings, each of them conected to a fourteen pulse bridge rectifier. The rectifier outputs may be connected in series to increase the generator output voltage. This paper presents a methodology that makes use of genetic algorithms for the solution of the economic dispatch problem. The proposed model considers multivalve generating units whith non-convex costs functions.
Numerical examples show the validity and effectiveness of the proposed methodology.
The problem of definition of the regimes that must be considered in tasks of optimum project for distribution network is discussed. This problem is formalized here in the form of redundancy reduction in the linear inequation system. The method and algorithm are developed for its resolution. The method is founded in lower and upper estimates of the multitude of strong restrictions. The criteria for these estimates and the general algorithm for the reduction are offered.
