要約(日本語)：This study analyzes the optimization of distributed energy systems in residential distribution networks by constructing a linear programming model. It compares two scenarios: a conventional system without inter-household electricity exchange and a system enabling peer-to-peer (P2P) trading. Furthermore, it incorporates aggregators and demand response (DR) through willingness-to-pay (WTP) to evaluate impacts on distributed energy resource (DER) capacities and system costs. Simulation results based on 100 households reveal that allowing P2P trading increases PV installation and reduces total system costs by up to 8.4%, indicating enhanced economic efficiency and renewable energy utilization.
