Communication plays a huge role in the operation of modern power systems. It permits a real-time monitoring coordination and control of the transmission, generation and distribution of electrical energy. As the modern grid grows towards an increased reliance on communication systems for the protection, metering and monitoring for as well as data acquisition for planning; there is a need to understand the challenge in the powers’ system communication and their impact on the uninterrupted supply of electrical energy. Communication delays are one of the challenges that might affect the performance of the power system and lead to power losses and equipment damage, it is important to investigate the causes and the mitigation options available. Thus, this paper the state of arts on the cause, the effect and mitigation of communication delays in the power system. Furthermore, in this paper an analysis of different causes of the delays for different network configurations and communication systems used; a comparative analysis of different latency mitigation methods and system performance simulations of a given compensation algorithm is tested against the existing methods. The pros and cons of these control strategies are illustrated in this paper. The summary and assessment of those methods of control in this review offer scholars and utilities valuable direction-finding to design superior communication energy control systems in the future.

A Comprehensive Review of the Evolution of Networked Control System Technology and Its Future Potentials

Networked control systems (NCSs) are attracting the attention of control system engineers. The NCS has created a paradigm shift in control system technology. An NCS consists of control loops joined through communication networks in which both the control signal and the feedback signal are exchanged between the system and the controller. However, its materialization faces several challenges as it requires the integration of advanced control and communication techniques. This paper presents an extensive review of NCSs from the perspective of control system design. The evolution of NCSs is broadly divided in three phases, namely NCSs prior to 2000, NCSs during 2001–2010, and NCSs from 2011 onwards. This division corresponds to the initial status, intermediate status, and the recent status of the developments in the design of NCSs. The advancement of different control techniques during these phases has been discussed comprehensively. This paper also describes the transition of control systems form continuous domain to networked domain, which makes it better than the traditional control systems. Some important practical applications, which have been implemented using NCSs, have also been discussed. The thrust areas for future research on NCS have also been identified.

In [15] the authors propose a networked linear–quadratic regulator (LQR) control scheme for a dual‐machine power system by considering communication‐induced delays. In [16], a centralized networked wide area damping control scheme is introduced to provide supplementary signals for FACTS devices to damp inter‐area oscillations.…”

“…But, in most of the existing literature the effects of the communication network have been ignored and it is assumed that the measured signals transfer through an ideal communication network with no delays or packet dropouts. A few exceptions to this are [10][11][12][13][14][15][16][17][18].…”

This paper presents a new networked hierarchical predictive sliding mode controller for the design of stabilizing signals to damp low frequency oscillations observed in geographically distributed networked power systems subject to communication network constraints. Firstly, through the generic framework of networked systems, a networked model is used for a distributed networked system in which network delays and data packet loss are considered in a wide area measurement system (WAMS). Then a hierarchical predictive sliding mode controller with robust reaching law is proposed to compensate the influence of WAMS communication latency and damp the inter-area oscillations. For this, firstly, the overall system is decomposed into small subsystems with non-sparse matrices and lower order; then a new suitable predictive sliding mode controller is designed to provide optimal performance. Furthermore, in order to coordinate the entire system, the gradient of interaction errors is used. The effectiveness of the proposed control framework is illustrated through numerical simulations on a 5-area, 16-machine power system with several interconnected areas. Simulation results show the capability of the proposed approach to enhance the networked power systems' damping in comparison with a conventional networked control method. KEYWORDS hierarchical control, networked control, power system stability, predictive sliding mode, wide area system 1 | INTRODUCTION Distributed wide-area systems commonly appear in the real world, in the form of, for example, power grids, chemical plants, water distribution networks, traffic systems, etc. Systems are wide-area systems if they can be decoupled or decomposed into a number of interconnected/interacting subsystems or if their dimensions are so large that using the usual analysis, optimization, and control methods cannot achieve an acceptable answer during reasonable computational time and efforts [1]. Such typical motivating problems arise in the control of widely distributed multi-area power systems with severe interactions. These problems are mainly due to large dimensions, modeling errors, disturbances, and uncertainties in such systems. The stability of modern power grids is one of the most important issues in the operation of these systems. The increasing size of wide-area electric power grids and the interconnection of these systems via weak tie
