Journey on Japan’s Demand Response and VPP
2011 The Great Earthquake (Fukushima Incident)
2012 Restart of Electricity System Reformation2014 Energy Plan (Including DR introduction) establishedDR導⼊を含むエネルギー基本計画
2015 DR Guideline (Operation Rules) established
ベースライン検討会(現ERAB検討会)活動開始
2016 Capacity procurement (including DR) auction started
VPP pilot project (2016〜2020) started
調整⼒Ⅰ´公募開始、VPP実証開始
2017 Ⅰ´ Reserve (DR) contract Aggregator-TSO started〜First implementation in 2018 ⇒capacity expanding
Ⅰ´の初発動と容量拡⼤
2020 End of VPP project ⇒RE balancing and DER multi-use

Japan’s Activities After 2018 on DSO & Flexibility
2018.9 Hokkaido Blackout, Hard Typhoon Attack to Japan Mainland(also in 2019)2018.10 METI platform study group started プラットフォーム研の立ち上げ～UK & US Flexibility cases introduced (WPD, piclo, NY REV.. )～Emphasis of advanced technology platform building～DSO&TSO tariff change to Revenue Cap (レベニューキャップ)～Possibility of local grid
～Change of metering rules for DER expansion⇒Transferred to practical rule change (各委員会等のタスクアウト)
2020.4

DSO and TSO DER utilization platform study started
by METI, NEDO ,Tokyo Power Glid, Kansai T&D, others

2020.6

New Electricity business Act enacted

2020.8Smart Resiliense Network established for DER utilization
TSOs, DSOs, Aggregators, DER companies participates
スマートレジリエンスネットワークが設立、活動中。

Difference between
Europe and Japan behind DSF

再エネ導入速度:風力を中心に早い
RE Increase →Rapid
卸(当日)市場 :活発な取引とネガプライス、変動大Intra Market→Active
DER(顧客側機器):
EV普及で先行
家庭用機器が大出力(kW)EV spreading, Appliances
配電ネットワークの余裕が少ない
DSO Robustness→Not enough

再エネ導入速度:太陽光中心で緩やか
RE Increase →Re
卸(当日)市場 :未発達、最低0.01円/kWh
Intra Market→Inactive
DER(顧客側機器):
家庭用蓄電池は多いがフレキシビリティ
未活用、他の機器は省エネ進み小出力
Residential Battery, EV on the way
配電ネットワークの余裕が大きく、配電線の切り替え能力が高い
DSO Robustness→Presently Enough次世代電力マネジメント産業(14分野の一つ)6

DER promotion policy for Carbon Neutrality(2021.7)〇分散型エネルギーリソース（DER）の活用最適化に向けた制度・市場
整備：市場規模 約３千億円～ DER market in 2030→3billion＄〇FITからFIP制度への移行による変動再エネの市場統合[2022年度～]
Promotion of Direct Marketing for FIT〇DERの価値取引市場（卸電力、需給調整、環境価値等）の要件整備（大規模電源との公平取扱等） Equality of Generator and DSF〇混雑緩和にDERを活用するローカルレベルの混雑プライシング、市場取引の創設検討 Local Energy Market(Including Flexibility)〇主なDER（蓄電池／EV、需要側リソース）の活用容易化に向けた取組

What is the comprehensive way to activate DSF
in Japan, including DSO voltage use??
〇規制当局とTSO/DSO自身の役割は何か
How should regulators and TSO/DSO make actions
for DSF utilization in Japan and other countries.
〇フレキシビリティのリソース選択はどうあるべきか。リソース間の競争性、契約等、プラットフォームをどう構築していくか。
What Flexibility resource will be used?? What function
will the flexibility platform prepare??
