Abstract
Description
グループの図示階層構造は、1つの可能性に過ぎない。多かれ少なかれ、異なるレベルのグループがあり、また、オリジナル最大電流は、決定に基づいて異なり得る。「グループ」という用語は、同じグループが両方になる可能性があるため、捉えかたによって親グループ、またはサブグループのいずれかを指すことができる。図8は、いずれの充電ステーションにもEVs充電が無いときの動的負荷管理の開始状況を図示する。グループA11、A12、A13、A21、A22の各々は、少なくとも1つの充電ステーション(図8には図示せず)を備え、各充電ステーションは、唯一のグループの一部である。さらに、グループA11、A12、A13はグループA1にグループ分けされる。それゆえ、グループA11、A12、A13はグループA1のサブグループであり、グループAは、グループA11、A12、A13の親グループである。同様に、グループA21、A22はグループA2としてグループ分けされる。それゆえ、グループA21、A22は、グループA2のサブグループであり、グループA2は、グループA21、A22のための親グループである。さらに、グループA1、A2は、グループAのサブグループであり、グループAは、グループA1、A2の親グループである。
