Controllable load, such as hydrogen supplying equipment 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 focus on frequency-watt control by a self-commutation type converter connected to a controllable load and have proposed a system for regulating active power. However, the load modeled as a controllable current source differs from the actual water electrolyzer load due to its static and linear characteristics. To reveal the controllability and economic efficiency of the system, this paper improves the system with a controllable load that has dynamic and non-linear characteristics is proposed. Moreover, the daily simulation using actual system frequency data, energy transaction data, and public offering regulation data verifies the compliance with the supply and demand reserve market requirements for primary frequency regulation capacity and evaluates the cost of hydrogen supply in the system.
