  • Direct power control (DPC) has increasingly gained attention in the last years as a robust and simple control scheme. Yet, the implications of some of the assumptions made by the original table-based DPC are not
    well explained in the literature. Here, a new formulation of DPC is
    presented, that allows to analyze the shortcomings of this kind of
    algorithms, mainly regarding the power limits in which table-based
    algorithms are valid. This is a key aspect for microgrid applications,
    as they require a wide range of possible active and reactive power
    setpoints in order to be able to control the system's voltage and
    frequency. A new table is then presented that allows to overcome those
    limitations. The proposed table is valid at any point of the inverter's
    power limits.
