  "textContent": "A power derating method for a photovoltaic tracking system, a controller and a photovoltaic tracking system are provided. A current operating power and a target derating power of a photovoltaic inverter are acquired. A total power derating amount is calculated based on the current operating power and the target derating power. A target power derating amount by a photovoltaic tracker is determined based on the total power derating amount and a preset derating amount distribution coefficient. A target tracking angle is determined based on the target power derating amount. The photovoltaic tracker is controlled to adjust a photovoltaic module to be at the target tracking angle and fix the photovoltaic module. The photovoltaic inverter is controlled to adjust a direct current operating voltage based on a difference between the total power derating amount and the target power derating amount.",
