ENERGY MANAGEMENT SYSTEM

摘要

An energy management system includes an overcharging-overdischarging risk storage and a generation storage optimization planner. The overcharging-overdischarging risk storage stores an overcharging-overdischarging risk indicating a risk for overcharging-overdischarging to a power storage device of a hybrid power conditioner for converting a DC power to an AC power to output the AC power to a power distribution system, the DC power inputted from a power generator or the power storage device, the hybrid power conditioner converting an AC power into a DC power to output the DC power to the power storage device, the AC power inputted from the power distribution system. The generation storage optimization planner calculates a control plan value for charging-discharging to the power storage device of the hybrid power conditioner on the basis of at least the overcharging-overdischarging risk, a power demand estimation, and a generated-power estimation for the power generator of the hybrid power conditioner.

1. An energy management system comprising:
an overcharging-overdischarging risk storage which stores an overcharging-overdischarging risk indicating a risk for overcharging-overdischarging to a power storage device of a hybrid power conditioner for converting a DC power to an AC power to output the AC power to a power distribution system, the DC power having been inputted from a power generator or the power storage device, the hybrid power conditioner being for converting an AC power into a DC power to output the DC power to the power storage device, the AC power having been inputted from the power distribution system; and a generation storage optimization planner which calculates a control plan value for charging-discharging to the power storage device of the hybrid power conditioner on the basis of at least the overcharging-overdischarging risk, a power demand estimation, and a generated-power estimation for the power generator of the hybrid power conditioner.
