Design and Stability of Voltage-Modulated Direct Power Control for Weak Grid Connected Voltage Source Inverters
Keywords:
Voltage source inverter, voltage modulated direct Power control (VM-DPC), vector current controller, weak grid, stable system.Abstract
In the weak grid –connected voltage source inverters the PLL system may make the system unstable if the conventional vector current control (VCC) method is applied, we design a voltage modulated direct power control (VM-DPC) for a three – phase voltage source inverter. In the proposed system of VM-DPC method the PLL method is eliminated as compared with the existing VCC method. When the rated real power injected to the weak grid, the VSI should generate some certain amount of reactive power too. In certain operating range, an eigen value based analysis shows the system with the proposed method tracks is desired dynamics. The simulation results match the theoretical expectations closely.
