Description
本願は、2017年12月15日に出願された「電力変換システム及び方法」という名称の米国仮出願第15/844,250号の優先権を主張するものである。上記出願の全内容は、すべての目的のために、ここに引用して援用する。
本説明は、電力変換および分配のためのシステムおよび方法に関する。本方法およびシステムは、太陽電池アレイおよび電気エネルギー貯蔵装置を含む電力システムに特に有用であり得る。
太陽電池のアレイは、太陽エネルギーを電気エネルギーに変換することができる。太陽電池のアレイによって供給される電気エネルギーは、直列に配置される太陽電池の数に依存する電圧で供給される直流(DC)の形態であってもよい。太陽電池によって供給されるDC電力は、インバータを介して交流(AC)に変換することができる。しかしながら、太陽電池の出力は、環境条件および太陽電池の条件によって変化し得るので、バッテリーセルが、太陽電池を含む電気システムに含まれてもよい。バッテリーセルは、AC需要が低く、太陽電池の電力出力容量が高い場合に、太陽電池からの電荷を貯蔵することができる。さらに、太陽電池の出力容量が低く、AC電気負荷が高い場合、バッテリーセルはAC電気負荷に電力を供給することができる。太陽電池からの電力が、第1のDC/DCコンバータによってバッテリー電圧付近にレベルシフト(例:より高い電圧からより低い電圧に調整される)され、DCバスを介して分配された後、バッテリーセルは、太陽電池から電力を受け取ることができる。DCバスからの電力は、第2のDC/DCコンバータによってACグリッドライン電圧付近にレベルシフトされ(例:より低い電圧からより高い電圧に調整される)、次いでインバータを介してACグリッドに供給される。しかしながら、この配電方式は2つのDC/DCコンバータを使用し、システムコストを増加させ、システム効率を低下させる可能性がある。したがって、効率を高め、システムコストを低減することができる電力を分配する方法を提供することが望ましい場合がある。
本説明は、DC電源を介して電力を生成し、DC電源から定常AC電力グリッドおよび電気エネルギー貯蔵装置に電力を分配することに関する。2つのDC/DCコンバータを利用してDC電源から定常AC電力グリッドに電力を輸送する従来技術にかかる電力変換システムが、開示されている。DC電源からの電力を定常AC電力グリッドに分配する電力変換システムと、DC電源からの電力を電気エネルギー貯蔵装置に分配するか、または電気エネルギー貯蔵装置からの電力を定常AC電力グリッドに分配する単独のDC/DCコンバータとを図2に示す。図2の電力変換システムの詳細な概略図を図3に示す。図2のシステムの種々の動作モードを図4A-4Dに示し、図2のシステムを動作させる方法を図5に示す。本方法は、電源と電力需要家との間で電力を分配する。最後に、電力変換システムから電力を受け取ることができる例示的な電気エネルギー貯蔵装置を図6に示す。
