Development of a Demand- Response System and Its Application to a Virtual- Power- Plant Construction Demonstration Project
●This paper introduces the system and describes our virtual power plant construction demonstration project, which has been ongoing since 2016.
▲Introduction
◆After the Great East Japan Earthquake in 2011, power supply capacity in Japan decreased due to the shutdown of nuclear power plants.
◆At the time of the earthquake, several “smart city” projects were underway in Japan, including demonstrations in which demand was controlled in accordance with the supply of electricity, which is called “demand response.” The major purpose of demand-response in Japan before the earthquake was reduction of CO-2 emissions.1 However, with the reduced power supply capacity of the electric power companies, the necessity of adjusting demand to meet supply increased, and demand response became more focused than before.
◆As a result of this situation, Japan’s Ministry of Economy, Trade and Industry started a Building Energy Management System (BEMS) Promotion Subsidy project in fiscal year 2012. Azbil Corporation was selected as an aggregator company in this project. It obtained visualizations of energy consumption through remote-controlled building management systems (BMSs) installed in multiple buildings, and implemented demand response according to the degree of constraint between the power supply and demand.
◆Thereafter, OpenADR, which is a communication protocol for demand response systems, was specified as a standard protocol by the OpenADR Alliance in the U.S., and has also been selected for use in Japan.2 For demonstration projects related to demand response that are led by the Ministry of Economy, Trade and Industry, OpenADR has become the de facto standard for communication.
◆Azbil has developed an ADR system, which is a demand response system using OpenADR, and has participated in related demonstration projects since 2015.
