ABSTRACT In April 2021, Japan implemented a balancing market to ensure more efficient and economical operation of control reserves. Since 2024, frequency containment reserves (FCRs) have been procured through this market. A committee of the Japanese Organization for Cross‐regional Coordination of Transmission Operators (OCCTO) is discussing cross‐border FCR procurement. Additionally, improving the resilience of the power system is necessary following the major blackout caused by the 2018 Hokkaido Eastern Iburi earthquake. To address these technical issues, we developed a simulation model for frequency analysis under emergency conditions. This model includes power plant models, renewable energy source models, load models, a frequency calculation model, tie‐line models and stabilizing control system models. We validated the simulation model by comparing its results with measured data on frequencies and tie‐line power flows.
