Application of PID Controller-Based Automatic Generation Control for Interconnected Power System with Governor Dead-Band Non-linearity Using MOL Algorithm M. D. Pabitra, Sangram Keshori Mohapatra, Asini Baliarsingh, and Radhakrishna Das Abstract In this paper, MOL algorithm is used in two-area non-reheat thermal power system in the presence of governor dead-band with PID controller is considered. For design and analysis of the purposed system, at first ISE and ISTE two objective functions are considered than 3rd type of objective function which is the modified form by using ISE, ISTE, IAE, ITAE and summation of power deviation and the settling times of frequency. For obtaining the dynamic performance of AGC, PID controller parameters are tuning by applying MOL technique. Then, superiority of MOL techniques is verified by comparing the published result in CPSO-based design of the purposed system. The transient analysis performance of MOL-based PI controller is superior than CPSO-based PI Controller. Keywords PID controller · MOL algorithm · Governor dead-band · AGC
1 Introduction When two or more power systems are interconnected, then its main function is generated, transmitted and distributed power in nominal range of system frequency [1–5]. The change of nominal frequency generally occurs due to mismatch of generation M. D. Pabitra Department of Electrical Engineering, BEC, Bhubaneswar, Odisha, India S. K.

of power and load demand. In order to maintain the balance of net power generation by synchronous machine which is sense for variation of frequency takes place in the power system to use the concept of AGC. As some researcher attempts the LFC of single- and multi-area system by applying different optimization techniques and controllers [6–8], the conventional PI type controller attempts in different LFC of single- and two-area system [9]. It shows that in convention PI type of controller, the dynamic performance is very poor in term of settling time of variation of frequency and variation of tie-line power and its overshoot. As in the literature survey, the AGC of fuzzy-based PI with tabu search algorithm applied in two-area system for LFC [10]. The LFC of generalized neural network with different controllers in AGC system is proposed in [11], the fuzzy logic-based controller in multi-area system [12], and fuzzy-neuro in hybrid approach [13]. In this paper, the Many Optimizing Liaisons (MOL) algorithm is used for optimization for controller parameters [14]. In the propo
