The power system is dominated by the renewable energy resources since last two decades. The main cause behind this enormous deployment of RES is to combat the global warming and to decrease dependency on fossil fuels. Wind energy is one of the abundant available sources of energy throughout the world. However, the huge deployment of wind energy in the power system cause vulnerability to the system. The main cause is the lack of system inertia in RES which cannot effectively respond during the power imbalance condition. To counter this effect, the virtual synchronous generators are deployed in the RES based power system. The VSG mimics the synchronous generator features and therefore it possesses the ability to provide the inertial support to system. In this paper, a wind base multiple VSG system is proposed to counter the frequency irregularities of the system. Furthermore, a comparison with classical droop control is done based on load variation. Moreover, the genetic algorithm is used to optimize the values of damping and inertia of the VSG. The performance of the proposed system is validated in MATLAB/Simulink 2019.

“…Notably, in PSs, the load disturbances such as variations in generation and oscillations in power angel will disrupt the systems outcome. Therefore, the issue of disturbances has been a prime issue in control design [33][34][35][36]. Recently, the linear active disturbance rejection strategy is developed in Ali et al [36] by formulating extended state observer to estimate the unpredictable disturbances and unmodeled parameters of a single area wind PSs and which are compensated by making use of PD control law.…”

This work is mainly focused on designing hybrid memory state feedback load frequency control law for a class of multi-area power systems against transmission delays, parameter uncertainties, actuator faults, and load disturbances via fault-alarm approach. More specifically, the load disturbances are prompted by the incorporation of abundance amount of renewable energy resources, namely, photo voltaic and wind power. Additionally, the power system takes the effect of actuator faults into account, which is unavoidable and exists at any instant of time. Thus, to stabilize the addressed system, the fault-alarm approach is exploited to develop the hybrid control law. Particularly, the state dynamics are well estimated by the aid of residual observer to detect the faulty condition of actuators. Also, by following the algorithm of fault detection, the spontaneous alert from the alarm is accomplished. Further, in consideration of appropriate Lyapunov-Krasovskii functional, the stability conditions having linear matrix inequality form are derived and which affirms the asymptotic stability of the power systems. Precisely, the controller gain matrices are obtained by solving the developed sufficient conditions. Eventually, the simulation results of two-area interconnected power systems are presented to examine the applicability and advantage of the proposed theoretical result.

“…Large penetration DFIG‐based wind turbine is an important issue in front of the electric power systems. It means that, DFIG must participate in the system frequency regulation and active power generation during any operating condition 13–15 . Therefore, some frequency regulators based on inertial response and frequency control have been extensively used, 16,17 which are scheduled by creating a relationship between the network frequency and active power of DFIG to support them during the disturbance conditions.…”

Since the DFIGs have been widely used in the modern electric power system, they must participate in the frequency regulation and active power generation during different internal and external disturbance conditions. The amassed kinetic energy in the rotating components due to acceleration and deceleration operating conditions can appropriately support the active power generation. Loss of the rotor speed equilibrium leads to overspeed of the DFIG's rotor and accordingly instability condition. An imbalance between power generation and demand can create a significant deviation in the frequency of the power system, that is, the speed and frequency of the generator increase due to reduced load and increased power, and vice versa. Hence, the frequency of the power system is basically considered a prominent measure for maintaining the balance of active power, while various frequency regulation strategies such as inertial response and frequency control have been widely used for DFIG. On the other hand, the synchronization control‐based power generation by DFIG can cause an instability condition during the severe disturbances. This paper proposes ASCS‐AHSMC to accurately regulate the system frequency and maintain the synchronization. To appraise the performance of the proposed controller, it has been compared with the conventional SMC and Fuzzy‐based SMC. Furthermore, DFIG experiences less stable conditions under different wind variation models and short circuit to validate the controllability of ASCS‐AHSMC. Finally, the performance of the ASCS‐AHSMC has been well approved under different disturbance conditions as compared with the conventional SMC and the Fuzzy‐based SMC.
