Evaluation of Community-based Electric Power Market with Multi-agent Simulation

Electric power trading has been adopted in many countries. In this paper, we focus on community-based electricity markets to reduce a demand of electric power and ensure an balancing supply of energy for renewable energy. The community can be defined as a domestic group of individual homes. We assume a community has a larger battery that can be shared by individual homes. In the real world, community-based battery sharing has been focused on as a useful electricity buffer in crisis situations and also for stabilizing usage of electricity in a domestic area. In this paper, we build several domestic electric power management agent models by using Japanese power consumption data and meteorological data. We evaluate community-based electricity markets by using agent-based simulation, in which the validity of the large-sized storage battery in a community is confirmed regarding the load mitigation to a power network.
