Document Type and Number:
Japanese Patent JP6920876
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply system which can effectively utilize power generated by a photovoltaic power generator unit of a first power storage system.SOLUTION: A power supply system 1 includes a supply unit including a plurality of photovoltaic power generator units 11, 21, 31 connected to a power route L. The supply unit includes: a first power storage system 10 connected to the nearest side to the load H side of the power route L; and a second power storage system 20 and a third power storage system 30 respectively which further include storage batteries 22, 32. The power supply system 1 includes: sensors 42, 43 which can detect a reverse power flow from the first power storage system 10 to a system power K; and hybrid power controllers 23, 33 which are configured to enable acquiring the detection results of the sensors 42, 43 and controlling the storage batteries 22, 32, and when the sensors 42, 43 detect the reverse power flow to the system power K, charge the reverse power flow to the storage batteries 22, 32.SELECTED DRAWING: Figure 5
