Main finding reveals significant bidirectional wake effects between two wind turbines in a hilly region of Japan.
The wind speed ratio decreases with inflow wind speed below rated levels, indicating operating state dependency.
Wake models in PyWake software overestimate reduction for northeasterly winds while underestimating for southwesterly ones.
This study advances understanding of how topographic effects alter wake phenomena, impacting wind turbine performance.
