“…Choosing the best input signal is based on earlier studies in [15,32,33]. Therefore the generator speed is considered as input to PSS in a two-area four-machine system and the input to the supplementary controller of SVC is the active power flow in line 1 -27.…”

This study presents a hybrid method based on generalised predictive control (GPC) and a proposed new hybrid shuffled frog leaping (NHSFL) algorithm to design stabilising signals to damp the multi-machine power system low-frequency oscillations. A linearised model predictive controller based on GPC is designed in which the proposed NHSFL algorithm is employed for optimising the cost function of the GPC. The numerical results are presented on a two-area four-machine and a five-area 16-machine power system. The effectiveness of the designed controllers is shown by considering various operating conditions. The proposed approach, which is called as GPC-NHSFL, is compared with a classical-based method, GPC algorithm and GPC-based standard SFL algorithm (GPC-SFL). The simulation results show the superiority and capability of the proposed approach to enhance power systems damping.

“…The simple conventional PI controllers, designed based on the linearized model of the system at the certain operating points, do not provide an appropriate dynamic response to various loading conditions and disturbances [6]. It can be shown that adding optimal robust auxiliary damping signals to the conventional PI controllers, is the effective strategy for stability enhancement [13]. The block diagram of the conventional PI and its damping controller for the series branch of the UPFC is shown in Fig.…”

“…Using the LMI approach with ∞ H loop shaping, a robust PSS design can be constructed [11]. Of course, a multi-objective synthesis, formed by both the time and frequency domain specifications from H 2 and ∞ H performance, may present more advantages over a single objective function [12,13]. Nevertheless, all of the cited controllers ignore the time delay, due to the measured input wide area signals.…”

A robust auxiliary wide area damping controller is proposed for a unified power flow controller (UPFC). The mixedproblem with regional pole placement, resolved by linear matrix inequality (LMI), is applied for controller design. Based on modal analysis, the optimal wide area input signals for the controller are selected. The time delay of input signals, due to electrical distance from the UPFC location is taken into account in the design procedure. The proposed controller is applied to a multimachine interconnected power system from the IRAN power grid. It is shown that the both transient and dynamic stability are significantly improved despite different disturbances and loading conditions.

“…A robust mixed H 2 /H ∞ based LFC of a deregulated power system including superconducting magnetic energy storage has been proposed in [28]. For other works regarding the application of mixed H 2 /H ∞ control into MGs, readers can refer to [29,30], etc. It is notable that, although a mixed H 2 /H ∞ control technique has been widely used in conventional power systems, there has been little work applying such control schemes into the field of EI.…”

Aiming at restructuring the conventional energy delivery infrastructure, the concept of energy Internet (EI) has become popular in recent years. Outstanding benefits from an EI include openness, robustness and reliability. Most of the existing literatures focus on the conceptual design of EI and are lack of theoretical investigation on developing specific control strategies for the operation of EI. In this paper, a class of control strategies for EI considering system robustness and operation cost optimization is investigated. Focusing on the EI system robustness issue, system parameter uncertainty, external disturbance and tracking error are taken into consideration, and we formulate such robust control issue as a structure specified mixed H 2 /H ∞ control problem. When formulating the operation cost optimization problem, three aspects are considered: realizing the bottom-up energy management principle, reducing the cost involved by power delivery from power grid (PG) to microgrid (MG), and avoiding the situation of over-control. We highlight that this is the very first time that the above targets are considered simultaneously in the field of EI. The integrated control issue is considered in frequency domain and is solved by a particle swarm optimization (PSO) algorithm. Simulation results show that our proposed method achieves the targets.
