“…It is well known that due to physical limitations, generation units have inherent generation rate constraints (GRC), such as ramp rate constraints and upper-lower bound constraints. If GRC is not considered adequately in LFC design, the controller will not yield excellent performances, and even the closed-loop system stability may be destroyed under disturbances [26][27][28]. In the aforementioned research work, some studies make tentative consideration on the GRC problem.…”

“…Therefore, the validity of these methods to deal with GRC lacks theoretical support. Towards LFC design with GRC, the extended integral control method in [26], the biased PI dual mode control method in [27], the Type-2 fuzzy approach in [28], and the anti-GRC PI-type controller in [29,30] are adopted to deal with the GRC problem. Unfortunately, the strict mathematical proof in the above methods is still absent.…”

Abstract:To deal with the problem of generation rate constraint (GRC) during load frequency control (LFC) design for a multi-area interconnected power system, this paper proposes an anti-windup controller design method. Firstly, an H ∞ dynamic controller is designed to obtain robust performance of the closed-loop control system in the absence of the GRC. Then, an anti-windup compensator (AWC) is formulated to restrict the magnitude and rate of the control input (namely power increment) in the prescribed ranges so that the operation of generation unit does not exceed the physical constraints. Finally, the anti-windup LFC is tested on the multi-area interconnected power systems, and the simulation results illustrate the effectiveness of the proposed LFC design method with GRC.

“…The GA optimization method faces some deficiencies like premature convergence which degrades its efficiency and the search capability [5,17]. LFC study of multi area interconnected power systems using type-2 fuzzy approach [14] and Variable structure fuzzy gain scheduling [15] has also been appeared in the literature. PSO is very important and powerful tool to solve the various engineering problems [5, 13,17].…”

This paper presents the Load frequency control (LFC) of a multi-source power system with Redox flow batteries (RFB). The power system comprises non-reheat thermal, hydro and gas generating units. RFB is integrated to the LFC system to improve the dynamic responses. The proportional plus integral (PI) controller is designed using the PSO technique. Dynamic responses are obtained by giving 1% step load perturbation (SLP) in the area. Further, to show the robustness of the controller, the dynamic responses are obtained by varying the SLP from 1% to 3%. Dynamic responses obtained in all the cases, satisfy the LFC requirements. PSO technique gives good convergence characteristics and promising computational results.

Summary This paper presents an initial work to design frequency stabilization strategies through, I, PI, PID, ID, and IDD calculated via the JAYA optimization process for load frequency control (LFC) framework of photovoltaic (PV) and thermal generators linked via AC tie‐line. Firstly, a comparative analysis of all LFC designs is conducted for typical load alterations, and the LFC recital is evaluated on basis of pick‐up value, inverse absolute error (IAE), inverse time multiplied by absolute error (ITAE) and the interpretation of graphical results. Additionally, the effects of an ultracapacitor combined with a redox flow battery and an ultracapacitor in each zone of the PV‐thermal system is also investigated and evaluated to improve the results of the PV‐thermal system. Finally, the effectiveness of the proposed plan is assessed for nonlinearity, continuous load alteration, and broad parametric varieties from the ordinary plant values. The application results are presented to show the novelty and benefits of the proposed work.
