• Subjects: APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC,OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWERSUPPLY SYSTEMS; CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTINGELECTRIC POWER; CONTROL OR REGULATION THEREOF; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUTPOWER; CONVERSION OR DISTRIBUTION OF ELECTRIC POWER; ELECTRICITY; GENERATION; SYSTEMS FOR STORING ELECTRIC ENERGY

The disclosed dispersed power supply system includes a power conditioner configured to control output of a power supply apparatus, a current sensor, another power conditioner configured to control output of another power supply apparatus and another current sensor, and when a forward power flow threshold for preventing a reverse power flow of the power conditioner is lower than that of another power conditioner, the power conditioner controls the output of the power supply apparatus to adjust the forward power flow that is higher than the forward power flow threshold to the forward power flow threshold, and then, if the forward power flow is higher than the forward power flow threshold when another power conditioner controls the output of another power supply apparatus based on another forward power flow threshold, increases the forward power flow threshold.
