Instantaneous adaptive P-Q theory based DSTATCOM with ANN for harmonic extraction

As non-linear loads are used, the power system faces many consequences, among which the quality of power is contemplated as a major concern. Hence it is vital to deliver the power without any disturbances which paves the way for this work, here PV fed DSTATCOM is employed, which also mitigates the harmonics. Instantaneous adaptive P-Q theory-based ANN is utilized for generating the reference current and the harmonic components are extracted using the gating sequence of the three-phase VSI. Thus, the opposite harmonics are injected at the point of common coupling (PCC) using three-phase VSI, thereby the active and reactive power flow in the distribution system is controlled. The proposed methodology is validated by using MATLAB simulation.
