Abstract

Systems and methods are provided, which provide for the de-centralization of the logic necessary to perform electrical optimization of any contained electrical system. The systems and methods de-centralize, or distribute, electrical optimization logic into intelligent devices which are locally connected to both the generation and loads, in such a way that control can be asserted over these resources. The inventive systems and methods require less infrastructure and communication backbone to IT/Data Center infrastructure than are typically required by previous systems and methods known in the art.
