Fault Tolerant Control System for Photovoltaic Panels Application

摘要： The paper presents a solution to control the power delivery system in a microgrid in which the primary energy source is using photovoltaic panels. The proposed mathematical models describe the operation of the main system blocks and are used as reference models in the fault detection mechanism. Using a complex control strategy, the generated power is controlled and the effects of the disturbances which occur in the system, including the faults, are rejected, making the proposed solution a robust and a fault tolerant one. The integrated control solution contains algorithms for the appropriate control of both the boost DC/DC converter and of the single phase inverter blocks. The proposed approaches are directed toward developing algorithms suitable for real-time implementation on 32 bit ARM processors.
