The microgrid is a typical model that takes advantage of distributed energy resources to improve reliability as well as reduce the load on the National power system. This thesis introduces a Microgrid (MG) model dedicated to factories with a large area, high energy demand and the potential to develop distributed power generation sources. The purpose of the thesis is to propose a model of a factory scaled microgrid based on the current characteristics of factories, and industrial parks in Vietnam. Based on this model, a control algorithm for the Energy Management system (EMS) is recommended to manage energy sources in the typical cases of a microgrid, such as ³*ULG-FRQQHFWHG´DQG³,VODQGLQJ´VWDWHV The factory scale microgrid operation is simulated in this thesis. The simulation model refers to an existing factory, which included distributed power sources such as diesel generators, Photovoltaic systems (PVs) and Battery Energy Storage System (BESS). The purpose is to see the adaption of the proposed algorithm for this grid. /r7UӏQK+RjQJ7kQ- 1970146 iv LӠ,&$0Ĉ2$1&Ӫ$7È&*,Ҧ LӠ,&$0Ĉ2$1&Ӫ$7È&*,Ҧ 7{L[LQFDPÿRDQ ÿӅ WjL luұQYăQWӕt nghiӋp ³7KL͇t k͇ YjOrQN͇ ho̩ch v̵QKjQK /˱ͣLÿL͏n nh͗ 0LFURJULGFKRP{KuQKQKjPi\´ OjF{QJWUuQKQJKLrQFӭu cӫa bҧn WKkQGѭӟi sӵ dүn dҳWYjKѭӟng dүn bӣi PGS.
