Abstract—Apartment management system. Aggregators in smart grid are business operators providing services to aggregate and visualize electricity information, balance demand and supply, < Final Year Projects > reduce energy consumption, and do the other activities with Energy Management Systems (EMSs). An aggregator for Apartment Building Energy Management Systems (Apartment-BEMSs) balances demand and supply considering all households in its building. The buildings with the BEMS are generally equipped with stationary batteries, PV generators, or the other devices to reduce energy cost and wasteful consumption. On the other hand, energy storages such as high capacity batteries are necessary to balance demand and supply in power grid installed a large amount of renewable energy such as solar power or wind power. However, these installation cost is expensive. Therefore alternative storages are required in some cases. As an approach, Vehicle-to-X (V2X) is carried out promptly. The V2X is a utilization of in-vehicle batteries installed in Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs) instead of stationary batteries. Then, the authors target constructing an effective EMS for apartment buildings with Vehicle-to-Home (V2H) systems. As the latest work, the authors propose an improved apartment BEMS considering characteristics of actual devices. Through computational experiments based on real data observed and measured in actual society, the authors show the effectiveness of the improved BEMS.
