摘要： 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.

摘要： An example energy storage system and a related method are disclosed. In the energy storage system, a controller obtains information about user equipment, and then controls a converter and a battery group based on the information about the user equipment, to supply electric energy to an electric device or receive electric energy from a power sourcing device. In this way, the energy storage system can provide reasonable power scheduling, thereby improving utilization of the energy storage system.

摘要： A grid-tied power supply system includes a controller and at least two inverters. One inverter is coupled to a plurality of power supply modules. The controller is configured to determine a power parameter. The inverter receives a power control packet through a communication transmission medium, determines target power based on the power parameter carried in the power control packet, and determines, based on the power control packet and/or the communication transmission medium, a target adjustment manner corresponding to the power control packet from at least two adjustment manners. The inverter further adjusts, to the target power in the target adjustment manner, power to be output by the inverter to an alternating-current (AC) power grid. The inverter can directly adjust power to be output by the grid-tied power supply system to the alternating-current power grid.
