Description
(1)熱電併給により、相当高い総合エネルギー効率(80%強)を期待できる。
(2)CO2排出量削減が期待できる。
(3)商用系統からの契約電力量の削減や配電施設の低減によるコスト削減が期待できる。
(4)震災、火災時の自立安定性が高い。
PLOAD=Asin2πft ・・・(1)
と表される。また、NiMH2の出力PNiMHは負荷電力に対して情報の伝達時間(本ケースでは計測1秒+制御1秒=2秒)だけ遅れるので、
PNiMH=Asin2πf(t−2) ・・・(2)
となる。これにより、負荷電力をNiMH2の出力が補償した残りの変動は、
PLOAD−PNiMH=Asin2πft−Asin2πf(t−2)
=|2Asin2πf|sin(2πft+φ) ・・・(3)
となる。NiMH2の出力によって負荷変動を補償するためには、(3)式中の正弦波の振幅に該当する|2Asin2πf|が元の負荷電力PLOADの振幅Aより小さくなる必要がある。すなわち、
|2Asin2πf|<A → f<0.083 ・・・(4)
である必要がある。このことは負荷電力PLOADのうち計測・情報伝送で制御システム4が負荷追従できない成分が0.083Hz以上の変動成分であることを示している。したがって、負荷電力PLOADのうち0.083Hz以下の変動成分は制御システム4によって変動を補償し、0.083Hz以上の変動成分はEDLC3によって自律的に補償させればよい。
Claims (2)
- 負荷変動に対する追従性能が異なる複数の分散型電源を統合的に制御する分散型電源の制御方法であって、
前記複数種類の分散型電源のうち、最も負荷追従性能の良い分散型電源を自律運転により負荷追従制御を行い、前記最も負荷追従性能の良い分散型電源以外の分散型電源は、デジタル通信網を経由して送信される制御システムからの指令により負荷追従制御を行うことを特徴とする分散型電源の制御方法。 - 前記制御システムは、前記最も負荷追従性能の良い分散型電源と前記最も負荷追従性能の良い分散型電源以外の分散型電源とから負荷に対して供給される電力を計測した値である第1の計測値と前記負荷追従性能の良い分散型電源以外の分散型電源から前記負荷に対して供給される電力を計測した値である第2の計測値とを前記デジタル通信網を介して受信し、前記第1の計測値と前記第2の計測値とに基づいて、前記最も負荷追従性能の良い分散型電源以外の分散型電源に対する出力指令値を求めて、前記デジタル通信網を介して前記最も負荷追従性能の良い分散型電源以外の分散型電源へ送信することを特徴とする請求項1に記載の分散型電源の制御方法。
