This paper presents a method for estimating the available active power reserve of a curtailed photovoltaic (PV) power plant composed of multiple inverters. The technique is based on a cyclic algorithm implemented in a plant controller, which calculates and sends active power setpoints to the individual inverters such that some of them operate in Maximum Power Point Tracking (MPPT) mode, while the rest are curtailed to follow a given setpoint at the plant level. When an inverter operates in MPPT mode, its active power measurement is stored in the controller memory, to be used as an estimation of its maximum available power (Pavail). The sum of the individual inverter Pavail estimations provides an estimation of the plant maximum available power. The inverters take turns being curtailed and operating in MPPT mode, allowing the Pavail estimations to be regularly updated such that the global maximum available power estimation accurately follows the variations caused by passing clouds or the sun's movement. The proposed technique is compatible with existing PV inverter technologies, and can be used to adapt existing PV power plants, enabling them to provide grid frequency control or other ancillary services based on active power flexibility and real-time estimation of maximum available power.
