論文概要: Against the background of energy shortage and secure supply requirements, renewable energy has developed steadily in recent years. As most distributed energy resources (DERs) are accessible in urban areas, interest has increased in regard to evaluating the potential advantages from introducing virtual power plants (VPPs) comprised of DERs into such areas. A VPP provides a solution for improving an energy self-sufficiency rate, as an alternative to expanding the capacity of a conventional power plant (CPP).
IN CHAPTER 1, the international as well as Japan’s energy situation, bottlenecks, and historical evolution were analyzed. These factors lead to the necessity of developing renewable energy sources.
IN CHAPTER 2, a detailed review of the application of VPPs was provided. IN CHAPTER 3, main research methods and VPP model were introduced.
IN CHAPTER 4, the energy consumption characteristics of buildings in Higashida area was analyzed.
IN CHAPTER 5, the feasibility of VPPs through the construction of local renewable energy and energy storage technology in Higashida area was evaluated.
IN CHAPTER 6, a VPP model consisted of updating high efficiency appliances, photovoltaic and energy storage systems was proposed. A comprehensive analysis for assessing the technical, economic and environmental benefits deriving from the VPP was presented. The energy-saving potential of a VPP composed of photovoltaic (PV) and energy storage system (ESS) and high efficiency appliances was explored, based on historical monitoring data in Higashida Smart Community The economic performance of the VPP was evaluated based on a payback period and total life cycle cost analysis.
IN CHAPTER 7, a comprehensive method for analyzing the feasibility of using a VPP to benefit both the plant and demand sides was proposed. Considering the imbalance of the benefits between the demand and plant sides, cooperative game theory was applied to explore the cooperation potential.
THE CHAPTER 8 is conclusions and prospects. Summarized the conclusions of each chapter.
