Analyzing the quality of supply under the insight of DC networks

By F J Santiago et al

Many topics are arisen nowadays in an effort to mitigate the constraints appearing on the energetic supply issue. One of them is the idea of concentrate the generation and consumption in certain areas defined as μGrids. All, reliability, quality of supply, energetic efficiency, economic profitability…, must be considered as a reality on the development of this new concept.

Supported by the rapid development of the power electronics, and aimed by the fact that an important part of the present domestic sector and of the small generation resources are based on direct current features (DC), the old Edison’s paradigm of a DC infrastructure comes again into discussion. On this paper, some advantages derived from the use of a low voltage network supported on a DC voltage are discussed, at the time that different scenarios where the DC system could result in a realistic alternative are proposed.
