The present study aims to propose a framework for the installation of distributed energy equipment, including cogeneration systems, photovoltaics, and storage batteries as well as emergency power generators, to enhance business continuity in a disaster-base hospital. Two types of simulation tools were developed: a planning tool and a verification tool. First, as a planning tool, a multi-objective optimization simulation with two objective functions was developed to determine the required amount of energy equipment. The first function was used to calculate the expected value of the ratio of electric power shortage to energy demand after disasters using an energy resilience risk index, and the second was used to calculate the total cost using an economic indicator. The optimal solutions formed the Pareto solution group. Next, the obtained solutions were verified to determine whether the energy demand in a disaster-base hospital would be satisfied by the energy supply of the installed distributed power generation equipment in case of disaster. For this purpose, an energy system simulator was developed as a verification tool. This simulator consisted of models of every piece of distributed energy generation equipment. Electric power generated by the gas engine generators of the cogeneration system, diesel engine emergency generators, and storage batteries is supplied to medical equipment as well as general equipment such as lighting and elevators. The installation of storage batteries to suppress fluctuations in the electricity supply was contemplated through the use of photovoltaics. The balance between the energy demand and supply was evaluated based on the frequencies of the alternating currents in the simulator. Finally, several case studies for different types of hospitals were examined.
