Robust control for voltage and transient stability of power grids relying on wind power

Adaptive Fuzzy Dynamic Surface Control for Multi-Machine Power System Based on Composite Learning Method and Disturbance Observer

“…The control gain functions g ij , j = 2, 3, 4, can be written as known part g ijN and unknown part ∆g ij , and χ for positive real number χ. Remark 1: The controlled object system includes two subsystems, which are excitation subsystem (6) and Static var compensator subsystem (7). There is coupling between the two controllers: the SVC subsystem (6) includes the state variables x i1 , x i2 , x i3 and control signal u i of the excitation system.…”

Energy storage management strategy in distribution networks utilised by photovoltaic resources

“…To address this issue, a number of researchers have investigated these obligations in different power system problems [18–24]. In more detail, the transient stability of power system is studied in [19], while the authors of [18, 20, 21] focused on the steady state classification discussing reactive power impact as well as the importance of voltage monitoring. Furthermore, the optimal location of capacitors in a distribution network based on some indexes of feeders’ voltage stability is evaluated in [25].…”

“…In this study, unlike all the above‐mentioned research on the topic of energy management with EES [1, 5–19], voltage stability is investigated through a new energy management regarding PV units, DGs and EES. Furthermore, instead of a commonly used typical case study, the problem will be conducted on a large‐scale distribution network to consider the associated operational and technical limitations, and to demonstrate the effectiveness of the proposed approach.…”

On transient stability of multi-machine power systems through Takagi–Sugeno fuzzy-based sliding mode control approach

“…In one such case, Ashraf et al have explored a Takagi-Sugeno fuzzy-based control approach in dealing with transient stability augmentation of multi-machine power system, while Bakhshi et al have considered fuzzy-based damping control approach though local measurements for the purpose of enhancing transient stability in power systems [1,2]. Schaab et al have considered robust control for voltage and transient stability of power grids focusing on wind power, and also Mazhari et al have addressed a frequency-domain approach for distributed harmonic analysis in multi-area interconnected power systems [3,4]. Darabian et al have presented a power control strategy, to improve power system stability in the presence of wind farms by designing predictive control and Shah et al have studied the performance improvement of intrusion detection with fusion of multiple sensors, while Wuthishuwong et al have focused on consensus-based local information coordination for the networked control of the autonomous intersection management [5][6][7].…”
