Abstract

The purpose of this paper is to examine the role that schools embedded in mechanisms such as virtual power plants and microgrids can play within their communities as renewable energy is being introduced toward decarbonization. When distributed energy, solar panels are installed in school facilities, their impact is not limited to the interior of the school, but inevitably affects the external community as well. As reference cases, this paper refers to the microgrid in the Santa Barbara Unified School District in California, USA, and the VPP pilot program in Australia. In the former case, 14 schools were equipped with relatively large photovoltaic installations and storage batteries to avoid power outages caused by natural disasters and to build up their function as community charters during emergencies. In the latter case, along with savings in electricity costs, the schools were integrated into the local VPP, contributing to the stabilization of the local power grid through smart control. In this way, the school's function as a community hub in times of emergency is strengthened, and the school becomes responsible for coordinating electricity supply and demand in an integrated manner with various distributed power sources in the community, thereby creating an energy-mediated connection with the community. As a result, the relationship between the school and the community will be strengthened in many aspects.
