This paper proposes an optimal dispatch strategy of hybrid power generation with battery energy storage system (BESS) for an islanding operation of Mae Hong Son (MHS). MHS is located in the far west mountain valley and there is plenty of renewable resources. Fault often occurs on the transmission line which supplies power to MHS. Therefore, it is a challenge to manage MHS as microgrids. The power system of MHS is based on national smart grid pilot plan and BESS is an important component to energy management system (EMS). Our dispatch strategy aims to minimize total operating cost while taking total CO 2 emission and load shedding proportion into consideration. Power dispatch problem is formulated as linear program with constraints involving power balance, hybrid power generation, and BESS operation. The numerical results show the power dispatch profiles MHS hybrid power generation components during islanding operation in various cases.
