Unit commitment in industrial microgrids with plug-in electric vehicles and photovoltaic generation

摘要

Industrial microgrids (IMGs) consist of factories with distributed energy resources (DERs) and electric loadsrnthat heavily rely on combined heat and power (CHP) systems. The new generations of IMGs are expected tornalso include renewable DERs and plug-in electric vehicles (PEVs) with different power ratings and chargingrncharacteristics. This paper proposes a profit-based security constrained unit commitment (PB-SCUC) formulationrnfor IMGs with PEV charging and renewable DERs that includes both microgrid security and factories constraintsrnas well as the PEV charging requirements. PB-SCUC will utilize the generators waste heat to fulfillrnthermal requirements and also consider the status of renewable DERs to decrease the overall cost of IMG.rnTo demonstrate the effectiveness of PB-SCUC, detailed simulation results are presented and analyzed for anrnIMG consisting of 12 factories and 6 types of PEVs without/with photovoltaic generations operating in gridconnectedrnand stand-alone modes.
