A hybrid energy system and a method for controlling the same

Japanese Patent JP5905929

B2

PROBLEM TO BE SOLVED: To make it possible to efficiently use renewable energy.SOLUTION: A control method for a hybrid energy system includes the steps of: increasing output voltage of an inverter by a control unit and accordingly increasing output voltage of a power converter when a public benefit energy supply source is not normal or is insufficient, and when output power of the power converter is larger than the total sum of power needed by a charge unit and power needed by a load or output power of the inverter is negative; actuating a voltage suppression function of the power converter when the output voltage of the power converter exceeds threshold voltage, where increasing the output voltage of the inverter causes increase in the output voltage of the power converter and decrease in the output power of the power converter; and by the control unit, determining whether or not the output power of the power converter balances with the total sum of power needed by the charge unit and power needed by the load.
