PHOTOVOLTAIC POWER GENERATION SYSTEM INCLUDING APPARATUS AND METHOD TO BUFFER POWER FLUCTUATIONS

摘要

A power generation system, apparatus and method to buffer power fluctuations are provided. At least one inverter (14) may be coupled to a photovoltaic power generator (10). The inverter may be subject to at least one operational constraint. A power-buffering circuitry (16) may be connected between the photovoltaic power generator and the inverter to buffer power generation fluctuations which can occur in power generated by the photovoltaic power generator, and satisfy the operational constraint of the inverter notwithstanding an occurrence of the power generation fluctuations. A controller (14) may be coupled to the power-buffering circuitry and may be responsive to the parameter of the photovoltaic power generator to perform at least one control action regarding the power fluctuations. Control actions may be performed by the controller independently of a control strategy of the inverter.
