Applying an intelligence-based adaptive multi-predictive control strategy to a two-area interconnected power system

Abstract

We look at a number of research works in the area of power system control to propose a novel strategy in line with the integration of intelligence-based techniques and also the adaptive multi-predictive control. In the strategy presented here, first of all, the one-area power system is represented, through sufficient mathematical relations, and subsequently the investigated outcomes are generalized to represent the two-area interconnected power system. Based on the proposed control strategy, namely IAMPCS in this investigation, the operating points of the two-area interconnected power system need to be represented through several linear models, where the best model of the system is accurately identified by an intelligent decision-maker mechanism at each instant of time. Hereinafter, an adaptive algorithm is instantly implemented on the chosen model to be efficient in the system representation and on the corresponding predictive control strategy, as well. In order to demonstrate the effectiveness of the proposed IAMPCS, the whole of simulation programs are carried out and the results are compared with those obtained using the single-model linear generalized predictive control, as well as the extended PI control schemes, as the benchmark one. The results verify the validity of the proposed control strategy in comparison with the previous approaches.

Load frequency control of new energy power system based on adaptive global sliding mode control

“…For instance, the variation of some parameters in power system may lead to the degradation of its performance and the phenomenon of oscillation. For the problem of system parameter variation, more scholars have studied the adaptive controller (Mazinan, 2013;Li et al, 2019;Zou, 2020;Wang et al, 2022b).…”

Proportional integral observer-based decentralized stabilization design scheme for nonlinear complex interconnected systems

“…Therefore, the overall interconnected system is then of high order and difficult to stabilize asymptotically. Nonetheless, in many applications of power systems, only simplified systems with reduced order are used for modelling each subsystem of the power plant (Jiang et al, 2004; Mazinan, 2012). Additionally, in many works, straightforward academic examples are utilized to validate the developed control approaches for such systems (Lu and Yang, 2010; Tong and Li, 2002).…”
