This paper introduces the transition process of the hydraulic turbine and the closing law of guide vanes in high, middle and low head, and establishes the multi-objective optimal model of the closing law. Based on the operating data, three parameters of the closing law are optimized in two broken line. The target value in the rated and largest head are better in new optimized closing law, even effectively...
Smart Grid will be a new way to the development of the power network. In the development of Smart Grid, how to integrate the Renewable Energy and the Distributed generation (DG) safely and reliably is a problem urgent to be solved. Siting and sizing of DG planning in Smart Grid construction are researched in this paper. A multi-objective optimal model is established and normalized in the DG number,...
A multi-objective optimal model is proposed that takes into account minimizing the investment cost of DG and the power loss of distribution network, maximizing the static voltage stability margin, and enhancing the reliability of supply. And this model includes an normalized risk area expressing the uncertainty of DG's output. The immune information processing mechanism of immune system is involved...
