Electrolyzer connected by a self-commutation type converter that can regulate active power has been identified as alternative regulating resources to stabilize the power system which has a high penetration of renewable energy generation. The authors have been proposed frequency-watt control by a self-commutation type converter connected to a controllable load and have proposed a system for regulating active power. The parallelization system to decrease hydrogen supply cost and encourage higher penetration of electrolyzer requires efficiency control because of variation in cell degradation caused due to equipment operation and individual difference. This paper proposed control method considering variation of cell degradation between multiple electrolyzers participating in reserve market. Moreover, the daily simulation using actual data in two electrolyzers system which differs degree of cell degradation is perfomed to reveal controllability and economically effect of the system participating in reserve market.
