Abstract
In a large hospital, an emergency generator (EG) is installed in the facility in preparation for power failure due to disasters and power system accidents. Emergency generators generate power by consuming fuel stored in the hospital, but since the stored fuel is limited, the operation time of EG will be limited. Also, in large earthquakes, traffic infrastructure is often destroyed, and it is difficult to replenish additional fuel to the fuel tank in the hospital. Therefore, in order to supply power as long as possible to the hospital using EG, need to install photovoltaic generator (PV) and power storage equipment, and optimize the operation method of EG and minimize fuel consumption. Previous research has optimized the operation method of EG applying mathematical programming method at a large hospital assuming install of PV. In this paper presents, we construct an emulation system that scales down the power grid of a large hospital and verify and evaluate algorithms of optimal operation method of EG, PV and power storage equipment during island mode operation.
