“…Previously, it has been revealed that the FO controllers deliver better performance than the conventional controllers. 13,27 Addition of the cascade control theory in FO controller may further enhance the system performance. Hence, in the past, few works on different design of cascade FO controllers have been reported.…”

Summary The present work primarily addresses a maiden application of fractional order calculus‐based cascade tilt‐integral–tilt‐integral‐derivative (CC‐TI‐TID) controller in load frequency control of deregulated power systems. Simultaneously, an efficiency test of a recently introduced water cycle algorithm (WCA) in obtaining optimal setting of CC‐TI‐TID controller is also investigated. In the proposed controller, TID controller acts as a slave controller, while TI controller played a role of master controller. Performance test of the proposed controller in stabilizing system frequency of a deregulated four‐area power system is carried out. In view of the above, firstly, superiority of WCA over other studied algorithms such as genetic algorithm, differential evolution, and teaching‐learning–based optimization techniques is established considering the proposed CC‐TI‐TID controller‐assisted four‐area power system. Secondly, comparative performance among WCA tuned proposed CC‐TI‐TID, CC‐PI‐TD, and PID controllers are explored in terms of chosen objective function, performance indices, settling time, and peak deviations. The comparative results obtained reveal that WCA tuned CC‐TI‐TID controller outperforms the others. Further, to check the robustness of the CC‐TI‐TID controller, sensitivity analysis is performed by varying Disco participation matrix.

“…Minimum values ofN may drive ripples in the phase behaviors. These waves can be handled by raising the values ofN, but the computational load of the estimation becomes difficult and complex in the hardware implementation [21]. In this article, 5th order Oustaloup's recursive estimation is considered while fitting frequency variety [ω l , ω h ] is taken as [0.01, 100] rad/s.…”

Now, combining Equations (21) and (22) gets the controller signal (u FOFPIDi (t)), in which u FOFPIDi (t) represents the pre-compensated term of the proposed strategy.…”

Load frequency control (LFC) is considered to be the most important strategy in interconnected multi-area power systems for satisfactory operation and distribution. In order to transfer reliable power with acceptable quality, an LFC mechanism requires highly efficacy and intelligent techniques. In this paper, a novel hybrid fractional order fuzzy pre-compensated intelligent proportional-integral-derivative (PID) (FOFP-iPID) controller is proposed for the LFC of a realistic interconnected two-area power system. The proposed FOFP-iPID controller is incorporated into the power system as a secondary controller. In doing so, the parameters of the suggested FOFP-iPID controller are optimized using a more recent evolutionary computational technique called the Ant lion optimizer (ALO) algorithm utilizing an Integral of Time multiplied Absolute Error (ITAE) index. Simulation results demonstrated that the proposed FOFP-iPID controller achieves better dynamics performance under a wide variation of load perturbations. The supremacy of the proposed FOFP-iPID controller is demonstrated by comparing the results with some existing controllers, such as fractional order PID (FOPID) and fractional order intelligent PID (FOiPID) controllers for the identical system. Finally, the sensitivity analysis of the plant is examined and the simulation results showed that the suggested FOFP-iPID controller is robust and performs satisfactorily despite the presence of uncertainties.

“…Handling violations within system capability and capacity is a big challenge faced by ISO. All LFC researches [14][15][16][17][18][19][20][21][22][23] under deregulated environment adopt tie line bias control. During violation, tie line bias control maintains TRANSCO power at scheduled value by permitting same area GENCOs to compensate for violated demand.…”

Load frequency control existing in restructured power system retains frequency change and transmission line power variations within limits. Tie line bias control strategy adopted for load frequency control allows only contracted power to flow through transmission line. Thus, during violation, this strategy does not allow transmission companies to utilize its available reserve beyond the contract. Concurrently, only same area generation units are rescheduled to satisfy violations. This paper proposes a new control strategy for load frequency control in a competitive environment considering transmission line reserve. The strategy allows the use of more economic generating units located in neighbouring areas, thereby making use of transmission company’s reserve up to the maximum limit during violation. The proposed strategy is tested for its effective and efficient performance under bilateral and poolco model with various contract violations. The strategy proves for the effective utilization of neighbouring generating units that offers lowest prices thereby making the system efficient.
