In any manufacturing process, production cost is of importance in the production process, one major part in production cost is the electrical energy cost. However, factory managers often pay little attention to energy costs in general, and electricity costs in particular, because they are simply regarded as "non-manageable." By applying electrical load management techniques industrial facilities could achieve cost saving in electrical energy consumption due to reducing the peak demand. This achievement could be reached by optimally scheduling the electrical loads/processes. This book discusses in details the importance of electrical load management as one of the hottest topics in present and next decades. Based on load shifting technique, it provides a systematic approach in modeling and analysis of load management practical problems.
