“…From the perception of oscillated motion in the synchronous machine at disturbance, if a change is occurred in the prime mover power from P m1 to P m2 , the operating point moves along the power curve, from point "A" to point "C" and then from point "C" to point "A" with oscillatory motion about point "B." The change in frequency in one cycle of the oscillation can be partitioned into four intervals as shown in Fig . 3 [26][27][28][29][30][31].…”

With the enormous stress of energy lack and air pollution, renewable energy sources such as photovoltaic sources become an effective solution to solve these problems. The penetration of inertia-less photovoltaic sources into power system has adverse effects on the overall system inertia which threatens system stability. As a solution for this problem, virtual inertia technique can be used as a system controller in order to enhance the system performance and maintain its stability. In this paper, an adaptive virtual synchronous generator (VSG) controller based on the oscillation motion of the synchronous machine is introduced. Then, a proposed VSG with adaptive neuro-fuzzy inference system (ANFIS) is presented as an inverter controller. The system response is investigated and compared with other control methods under different operating scenarios. To verify the effectiveness of the proposed adaptive VSG, an experimental setup is presented with real-time implementation for the system using dSPACE DS1104 interfacing with MATLAB software, and the system response is investigated under different operating scenarios. Upon the presented results, there is an enhancement in the system response when the proposed adaptive VSG with ANFIS controller is used, and this emphasizes the superiority of using such controller in PV systems over other techniques.

“…However, because they differ in physical structures, control principles, and parameters [3] , large power oscillations are generated within the paralleled system when loads fluctuate. It degrades the power supply quality and may even exceed Manuscript received January 20, 2021 the thermal current limitation of the power electronic device-based VSG [4][5] . Many investigations have been performed on the operation characteristics of a standalone VSG or paralleled VSG system in a microgrid.…”

A virtual synchronous generator (VSG) can provide inertial support through renewables and energy storage. It generally operates in parallel with a diesel generator (DSG) in an islanded microgrid. However, unforeseen interactive power oscillations occur in the paralleled system when loads fluctuate. These may also burn out the VSG owing to its low overcurrent capacity. The mechanism and suppression strategy of the power oscillation of a VSG-DSG paralleled system are investigated. It reveals that the interactive power oscillation is caused essentially by the physical difference and parameter mismatch between the VSG and DSG.Then, the elimination condition of oscillation generation is derived. Subsequently, a comprehensive suppression control strategy based on virtual inductance and dynamic mutual damping technology is proposed. Finally, the experimental results verify the effectiveness of the proposed method.
