In a system that suppresses power fluctuation caused by wind power and solar power generation by a storage battery (We call it wind turbine and photovoltaic power generation system, WPBHS), it is assumed that the number of constituent equipment is large. Therefore, by dividing the constituent equipment into a plurality of groups (We call it grouping), the operation plan is optimized dispersedly. In this case, it has been shown that WPBHS has fault tolerance by overlapping storage batteries in plural groups. Also, enumerating the grouping in advance allows us to switch the grouping and recover the system immediately when a system failure occurs. Motivated by this, we consider an overlapped grouping optimization problem focused on the performance deterioration and fault tolerance of the distributed management system. Enumerating the group, especially, the overlapped group requires large computational load with the more devices added. First, this paper formulates overlapped grouping optimization for WPBHS. Second, this paper proposes a graph representation method of the overlapped grouping and a near-optimal enumeration method.
