Abstract |
|
|
| This paper presents a DSP based high-performance power flow control scheme for the distributed generation (DG) inverter.
The design of control scheme is based on a detailed dynamic model of the 3-phase voltage sourced inverter. In the dynamic model,
the DG energy source is represented by a constant DC voltage. To achieve better dynamic performance, the output power flow of
the inverter is controlled through a P-Q decoupled control algorithm based on two independent regulation loops for d-q currents. The
proposed control scheme with various DG operating conditions is firstly simulated in the PSIM software environment to check the
performance of the designed controllers and followed by a set of DSP based experimental tests. The results obtained have demonstrated
the feasibility and effectiveness of the proposed control scheme in providing a desirable dynamic performance of fast real and reactive
power regulations of the grid-connected DG inverter. |
