和文要約
英文要約In this fiscal year, we built a demonstration system and started to operate the demonstration system. The operating characteristics of each device/system and the fluctuation compensation characteristics of the entire system were evaluated. In order to achieve a long time continuous operation, we investigated the operation and control methods suitable for maintaining the residual energy of the EDLC and the amount of stored hydrogen gas in the hydrogen gas tank within set ranges.
(1) Study on the need of water purification plants for this system and the effective control method of each device for using this system in the water purification plants
・We evaluated the characteristics at switching from a partial load operation to a full load operation, and verified that the system can respond instantaneously without delay.
 ・Evaluation of the utilization efficiency of solar power output before and after a load shifting confirmed that the utilization efficiency after the load shift on a certain sunny day improved by about 10% compared to before the load shift.
(2) Study on the suitable device for compensating short-term fluctuation output of solar power generator in this system
 ・An initial charging method of EDLC at starting of the entire system was established in the demonstration system.
 ・A control method of residual energy in the EDLC using the voltage across the EDLC was established by considering all converter losses, and the control parameters effective for controlling the residual energy was clarified.
 ・The voltage across the EDLC was maintained at 210 V ± 30 V by a control method considering the residual energy of the EDLC, and the DC bus voltage was able to be maintained with high accuracy (380 V ± 0.5 %).
(3) Study on the constitution method, operation method, and control method of a model hybrid power storage system for a verification test in the Moniwa water purification plant.
 ・The energy conversion efficiency at the FC output of 8 kW or less was evaluated by measuring the output power of the FC on the DC-BUS side and the hydrogen gas flow rate between the FC and the hydrogen gas tank, and found to be 15% to 32%. Note that it was assumed that the energy possessed by hydrogen gas of 1Nm3 was 10.74 MJ.
 ・We established a control method of simultaneous operation of EL and FC suitable for suppressing deterioration of FC, and found that the operation efficiency at the time of simultaneous operation of FC and EL was about 10 to 15% lower than that at the time of individual operation.
 ・The energy conversion efficiency at the EL input of 16 kW or less was evaluated by measuring the input power of EL on the DC-BUS side and the hydrogen gas flow rate between the EL and the hydrogen gas tank, and found to be 55% to 65%.
 ・It was found that the larger the Q value of the Kalman filter, the smaller the rated capacity of FC and EL can be.
 ・It was found that the rated capacity of EDLC can be reduced by increasing the Q value of the Kalman filter.
