Load frequency control of a two-area multi-source power system using a tilt integral derivative controller

Abstract

This paper introduces a tilt integral derivative controller as the supplementary controller for load frequency control of a two-area interconnected power system. The optimal value of parameters of the tilt integral derivative controller is evaluated using constrained nonlinear optimization by means of a performance index-based method. The proposed tilt integral derivative control offers superior properties such as simple parameter tuning and its performance does not compromise the occurrence of any parameter variations in the system. To verify these features of the controller, the test system is subjected to step load disturbance and parameter variations that ensure the robustness of the tilt integral derivative controller. Comparative analysis with previously published work indicates that the proposed tilt integral derivative controller gives better performance and holds the property of robustness. Simulations have been performed using Matlab Õ .

SMES based a new PID controller for frequency stability of a real hybrid power system considering high wind power penetration

“…Utilising (1)- (8) and the block diagram of Fig. 3, the dynamic equations of the studied hybrid power system can be derived and written in the state variable form as follows: Hence, the complete state-space equations for the EPS considering HWPP and the effect of the dynamic contribution of SMES technology can be obtained by (see (11)) . The state variables of matrices are Fig.…”

“…To face this issue, various optimisation algorithms were applied in the LFC loops of the interconnected power systems to obtain the optimal design of the PID parameters. Conventional methods, such as interior-point algorithm (IPA) [11], aggregation method by Aoki [12], tracking approach [13], and fixed mode evaluation algorithm [14] were implemented for LFC issue. However, these methods [11][12][13][14] suffer from stagnation, trap in local minima during the optimisation process, and need numerous iterations to guarantee that the solution is converged (i.e.…”

Secure Load Frequency Control of Smart Grids under Deception Attack: A Piecewise Delay Approach

“…In the 1970s, Elgerd and Fosha firstly applied Control Theory to the load frequency control (LFC) problem of interconnected power systems [2]. Since then, many researchers have been working on the LFC analysis with variety of control methods [3][4][5][6][7][8][9]. To mention a few, Reference [3] designed an adaptive load frequency controller for a two-area power system and proposed an optimal control scheme.…”

Differential evolution algorithm based tilt integral derivative control for LFC problem of an interconnected hydro-thermal power system

“…Another fractional order control recognized as TID control has recently emerged as a potentially good controller for LFC problems. TID control has been reported to be applied to the thermal-thermal LFC model and multi-source LFC model (Topno and Chanana, 2015; Topno and Chanana, 2016a, 2016b, 2016c). However, the TID control has not been implemented earlier for the LFC problem of a hydro-thermal power system.…”
