Experimental Report of Oneself-to-oneself Surplus Electricity Transaction Scheme between Remote Points introducing Power Exchange System

Abstract

Japanese electric power system has been liberalized in multiple stages and feed-in-tariff (FIT) of the renewable energy system such as solar power generation (PV) has been adopted for the limited period. Now many PV systems have finished the FIT period. So, expectations for many types of electricity transaction between individuals such as use of home surplus electricity for EV charging at workplace are emerged. From this point of view, this paper reports our trial implementation and results of experiment about an oneself-to-oneself electricity transaction scheme using a system with block-chain technology.
