Abstract

The purpose of this study is to develop an energy sharing scenario for buildings within the community. This work developed an energy sharing scenario for buildings in a community consisting of several types of buildings. The community are mainly composed of low-rise building, including offices. Six buildings with energy usage measurement equipment installed in the community were selected and the energy use status of the building was measured. The electric energy consumption and electric energy production of buildings were predicted using a simulation program. Electrical energy was produced using photovoltaic panels installed in buildings. Energy consumption patterns of buildings were analysed. There are four scenarios in which the energy produced is shared with each building. The first scenario uses photovoltaic as much power as it generates, and does not use surplus power. The second scenario is to reverse transmission the surplus power to the source. The third scenario is to store surplus power in the ESS and use it for the next day's peak load. The fourth scenario is to collect surplus power into the Community's ESS and share it with the most energy-intensive buildings. After comparing the four developed scenarios, it was found the most efficient and optimal sharing scenario based on buildings in the community. Results can be used as a method for sharing electrical energy produced using photovoltaic system in a small-scale community.
