| Sumario: | Due to increasing level of power converter based component in the grid and consequently the lack of inertia, AGC in multi area interconnected power systems are experiencing different challenges. To cope with this challenging issue, a derivative control based virtual inertia for simulating the dynamic effects of inertia emulations by HVDC interconnected systems is introduced and reflected in the multi-area AGC system. Derivative control technique is used for higher level applications of inertia emulation. By using this proposed combination in AGC model, the dynamic performance of the system shows a significant improvement. The virtual inertia will add additional degree of freedom to the system dynamics which makes a considerable improvement on first overshoot responses in addition to damping characteristics of HVDC links. |
