This application discloses a photovoltaic station and a power coordination method for a photovoltaic station. Sample inverters are disposed in arrays requiring power adjustment in the photovoltaic station. Real-time active power of sample inverters in each array is obtained. Then, an available active capacity and an available reactive capacity of the array and available active capacities and available reactive capacities of all the arrays requiring power adjustment are obtained based on the real-time active power of the sample inverters. Finally, active power and reactive power of the photovoltaic station are separately allocated to the N arrays based on the available active capacities and the available reactive capacities respectively corresponding to the N arrays. Because the sample inverters come from the arrays requiring power adjustment, differences between inverters and differences between the arrays can be fully exploited, and the available active capacities of the arrays can be more accurately obtained by using the sample inverters. Therefore, a more accurate available power capacity of the photovoltaic station is obtained by using relatively accurate available active capacities.
