Due to a rapid increase in the utilization of power converter-based renewable energy sources (RESs), the overall system inertia in an interconnected power system might be significantly reduced, increasing the vulnerability of the interconnected power system to the system instability. To overcome problems caused by the significant reduction in system inertia, this paper proposes a new application of virtual inertia control to improve frequency stability of the interconnected power system due to high penetration level of RESs. The derivative control technique is introduced for higher-level applications of virtual inertia emulation. Thus, the proposed virtual inertia control loop has a second-order characteristic, which provides a simultaneous enabling of damping and inertia emulations into the interconnected power system, enhancing frequency stability and resiliency. System modeling and simulation results are carried out using MATLAB/Simulink ® (R2016b, MathWorks, Natick, MA, USA). Trajectory sensitivities are also performed to analyze the dynamic effects of virtual inertia control's parameters on the system stability. The effectiveness of the virtual inertia control concept on stability improvement is verified through a multi-area test system with high RESs penetration level for different contingencies.

“…In recent years, there is an interesting idea that this kinetic energy can be released to respond the frequency fluctuation caused by power disturbances.

Summary Frequency stability is vital for the operation stability of power system. The total equivalent rotational inertia of power system decreases relatively upon large‐scale penetration of wind power and threaten its frequency stability further. This paper analyzes the inertia support capacity of doubly fed induction generator and proposes a modified virtual inertia control strategy based on power‐frequency response by improving the conventional control strategy. For each specific case, a corresponding control scheme is chosen. Besides, the rotor speed is protected by a control module associated with the secondary frequency regulation. Finally, an IEEE 14‐bus system with doubly fed induction generator is established in DIgSILENT/PowerFactory simulation software, to verify the effectiveness of the proposed control method, which can respond to the frequency changes rapidly and effectively inhibit the frequency fluctuations caused by load changes and wind energy fluctuation.

Abstract:Due to increasing level of power converter-based component and consequently the lack of inertia, automatic generation control (AGC) of interconnected systems is 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 (highvoltage direct current) interconnected systems is introduced and reflected in the multi-area AGC system. Derivative control technique is used for higher level applications of inertia emulation. The virtual inertia will add an 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. Complete trajectory sensitivities are used to analyse the effects of virtual inertia and derivative control gains on the system stability. The effectiveness of the proposed concept on dynamic improvements is tested through Matlab simulation of two-area test system for different contingencies.
