Abstract
Description
図1は、実施の形態1に係る蓄熱システム100の構成の一例を示すハードウェア構成図である。図2は、実施の形態1に係る蓄熱システム100の構成の一例を示す機能ブロック図である。実施の形態1に係る蓄熱システムは、蓄熱システム制御装置10が外部の電力制御指示機器30からの電力需給情報に基づき蓄熱装置20の運転スケジュールを生成又は変更するものである。また、蓄熱システム制御装置10は、蓄熱装置20の運転スケジュールに基づき蓄熱装置20の電力の需要に関する情報を電力制御指示機器30へ送信するものである。
蓄熱システム制御装置10は、蓄熱装置20と一体又は独立して設けられたものであり、外部の電力制御指示機器30及び蓄熱装置20と通信可能に接続されているものである。蓄熱システム制御装置10、電力制御指示機器30及び蓄熱装置20は、無線又は有線による通信路を介して情報を送受信可能となっており、通信路は例えばインターネット又は電話回線等の広域ネットワークを含み得る。実施の形態1においては、一例として図1に示す様に、蓄熱システム制御装置10が独立した装置として設けられた形態を用いて説明している。しかし、蓄熱システム制御装置10は、例えばサーバ上に存在していても良いし、独立した装置としてネットワークに接続されていても良いし、ネットワークに接続された蓄熱装置20又は電力制御指示機器30と一体に設けられていても良い。また、蓄熱システム100が実現する各機能は、ネットワークで接続された各機器、即ちサーバ、蓄熱装置20及び電力制御指示機器30などに分散して配置され、各機器間で必要な情報を送受信して蓄熱システム制御装置10の各機能を実現しても良い。
蓄熱装置20は、例えば各家庭に設置された給湯装置であり、ヒートポンプ部25、ヒートポンプ部25で沸かした湯を貯留する貯湯部26、センサ27及び制御装置21を備える。
電力制御指示機器30は、例えば地域の使用電力及び供給電力を管理する装置である。電力制御指示機器30は、ある地域の使用電力及び供給電力の情報を有しており、蓄熱システム制御装置を含む地域の需要家に地域の使用電力及び供給電力の情報である電力需給情報を作成する作成部を備える。必要に応じて蓄熱システム制御装置10は、蓄熱装置20が所属する地域の全体の使用電力、供給電力及び供給電力の予定などの情報を含む電力需給情報を電力制御指示機器30から取得できる。実施の形態1においては、一例として図1に示す様に、電力制御指示機器30が独立した装置として設けられた形態を用いて説明している。しかし、電力制御指示機器30は、例えばサーバ上に存在していても良いし、独立した装置としてネットワークに接続されていても良いし、ネットワークに接続されたいずれかの機器内に設けられていても良い。また、電力制御指示機器30が実現する各機能は、ネットワークで接続された各機器、即ちサーバなどに分散して配置され、各機器間で必要な情報を送受信して電力制御指示機器30の各機能を実現しても良い。
図3は、実施の形態1に係る蓄熱システム100において、蓄熱システム制御装置10による蓄熱装置20の制御及び電力制御指示機器30への運転スケジュール送信についてのフローチャートである。図4は、蓄熱システム制御装置10により処理される蓄熱装置20の運転スケジュール及び電力制御指示機器30から取得される電力需給情報の一例である。図4において、一番上に示されている表が蓄熱装置20の運転スケジュールである。図4において上から2つ目に示されている表が電力制御指示機器30から取得される電力需給情報であり、蓄熱装置20が属する地域の情報を示したものである。
以上に説明したように、実施の形態1に係る蓄熱システム100は、蓄熱システム制御装置10が電力制御指示機器30から得た電力需給情報に基づいて蓄熱装置20の運転スケジュールを変更するため、電力制御指示機器30が管理する全ての機器の電力需給に対応した蓄熱装置20の制御を行える。また、負荷予測により得た蓄熱システム制御装置10の運転スケジュールと電力制御指示機器30から得た電力需給情報とを比較することにより、電力の供給が逼迫した時間帯の蓄熱装置20による蓄熱(例えば湯沸かし)を避けることができる。具体的には、蓄熱システム制御装置10は、事前に得られた電力の供給が多い時間帯に、蓄熱装置20を蓄熱運転させるように制御する。これにより、ユーザーは、湯の使用量が多い時間帯においても貯湯部26の湯切れが発生することがない。
蓄熱システム100の蓄熱システム制御装置10は、単独の端末であっても良いし、特定の蓄熱装置20内に内蔵された制御装置21であっても良い。また、蓄熱システム制御装置10は、クラウド上においてプログラムにより実行される仮想的な制御装置であっても良い。蓄熱システム制御装置10は、蓄熱システム制御装置10が実現する各機能がネットワークで接続された各機器、即ちサーバ、蓄熱装置及び電力制御指示機器などに分散して配置された形態でも良く、各機器間で必要な情報を送受信して蓄熱システム制御装置10の各機能を実現しても良い。
実施の形態2に係る蓄熱システム100について説明する。実施の形態2においては、実施の形態1に係る運転スケジュールの生成又は変更後に、蓄熱システム制御装置10が再度電力制御指示機器30からの電力需給情報を取得して蓄熱装置20の運転スケジュールを変更する処理について説明する。なお、実施の形態2において、実施の形態1と共通する部分には同一の符号を付し、詳細な説明を省略する。実施の形態2においては実施の形態1からの変更点を中心に説明する。
従来のように、電力制御指示機器30からの電力需給情報に基づいて使用電力のピークカットを実施すると、電力制御指示機器30に接続された他の制御装置も含めて一律でピークカットを行うことになる。その場合、電力制御指示機器30における使用電力と供給電力との需給関係は、需給関係が成立するときは需要が過剰に供給を下回り、それ以外は需給関係が成立しないという2択の状況になってしまうという課題があった。しかし、実施の形態2に係る蓄熱システム100は、例えば蓄熱システム制御装置10が電力制御指示機器30からの電力需給情報に基づき、蓄熱装置20の運転スケジュールを変更することにより、電力制御指示機器30における電力需給調整の成立又は不成立に合わせて蓄熱システム制御装置10に接続された蓄熱装置20の使用電力を調整できる。そのため、電力制御指示機器30の電力需給調整に柔軟に対応でき、電力制御指示機器30に接続された他の機器も含めた全体の需給調整に寄与できる。
実施の形態3に係る蓄熱システム100について説明する。実施の形態3に係る蓄熱システム100は、実施の形態1及び実施の形態2に係る運転スケジュールの生成又は変更を行うが、制御する対象となる蓄熱装置20が複数になっている。なお、実施の形態3において、実施の形態1又は2と共通する部分には同一の符号を付し、詳細な説明を省略する。実施の形態3においては実施の形態1又は2からの変更点を中心に説明する。
