Optimal Operation of a Residential Microgrid: The Role of Demand Side Management

摘要: In this paper demand side management (DSM), characterized by shifting techniques, is applied to a residen- tial microgrid. It supposed that the microgrid managed prosumer, decision maker who manages distrib- uted energy sources, storage units, ICT elements, and loads involved in grid. DSM considered as an integral part of optimal economic short-term problem such allocation shiftable treated vari- able must be determined simultaneously with all others variables (i.e. exchange main grid, inter- nal production, charge/discharge electrical units). This focuses on formulation model includingfunctionallinksbetweenshiftableandshiftedloads operation costs. The implemented using IBM ILOG CPLEX optimization programming language solver. analysis shows how variable related other are linked (directly or indirectly) price parameters typical devices. Moreover, allows easily perform sen- sitivity analyses varying considered.
