“…Hence, high transmission delays and low precision are typical characteristics of SCADA [69], [70]. In terms of control, the update period of SCADA limits its application for fast and complex control actions, especially during contingencies [72], since real-time dynamics cannot be observed.…”

Countries around the world are transitioning from conventional power systems dominated by synchronous generators towards low-carbon resources, characterized by high levels of converter-interfaced generators (CIGs). With this transformation, hundreds or even thousands of fast power electronic devices will be added to the grid as CIG penetration increases, thus making the system dynamic response progressively faster and more complex. This future scenario poses significant challenges in power system stability and control. To sustain power system stability in future power systems and achieve a seamless transition, we need to depart from current control practices based on decentralized and stand-alone local control actions and begin to explore new methods. A promising technology to overcome control complexities and underlying stability issues in future low-inertia power systems are wide area control (WAC). Within this technology, the control is no longer based on a purely localized tasks but rather a set of coordinated actions across wide areas in which interplant communication plays a key role. This paper presents the state of the art of existing research efforts in the field of WAC strategies for maintaining stability in large-scale low-inertia power systems of the future. We present different WAC solutions that have been put forward hitherto, we put these control strategies into context, classify them, and finally relate them to each other. We also raise open questions and challenges that need to be addressed in order to ensure a secure transition towards power systems dominated by CIGs.

“…Among the consequences of the oscillations is the disconnection of the electric lines connecting two areas or more, so each area must increase the production of electric energy in order to balance between production and consumption of electric energy which also increases the carbon dioxide emissions. The objective of our research is to improve the interconnections between regions in order to increase the availability of electrical energy across several areas In order to improve the interconnection oscillations, we proposed the use of phasor measurement unit PMU technology for synchronization and taking real-time measurements [7], and an interconnection control system for the closure of interconnection lines in the case of increased demand to energy consumption, with this solution we avoid the rate of operation of power plants so the use of fossil energy is also reduced by improving interarea oscillation.…”

<span lang="EN-US">Many international organizations have called for reducing usage of renewable energy as a means to reduce carbon dioxide emissions, this paper studies the case of electricity production based to fossil fuels. Currently existing solutions is to shift from fossil fuels to clean renewable energy. Electrical interconnections are used between large-scale areas; these interconnections have a major problem that is the phenomenon of oscillations. The amount of fossil energy used by power plants depends on the electrical load required. with these conditions it is not possible to reduce the amount of energy required to satisfy the electrical load required. The solution proposed in this paper is the improvement of interarea oscillation using phasor measurement unit technology for real-time monitoring and accuracy of measurements. We tested the proposed solution for the north African power system. The results show the importance of improving interconnection networks to reduce fossil fuels use.</span>

“…The majority of these papers utilize a set of equations and redundant measurements obtained from state equations to obtain the parameters [4,5]. However, with the advent of phasor measurement units (PMUs), new methodologies for real-time applications have been developed, as the reporting rate of these devices is significantly higher compared to common Supervisory Control and Data Acquisition (SCADA) systems [6].…”

This paper proposes a nonlinear analysis of the parameter estimation problem in overhead and submarine power cable applications. The proposed methodology is able to estimate both positive and zero sequence parameters. Also, the measurement model incorporates random uncertainty in a rigorous manner, addressing the issue of noise propagation after applying symmetrical components. Three nonlinear estimation methods were studied to address the nonlinear least squares problems. Several noise levels and sample sizes were considered to demonstrate the robustness of the proposed approach. Finally, the methods were validated using both a simplified 2‐bus system and the IEEE 14‐bus system. The results obtained demonstrated significantly better performance compared to similar results found in the technical literature.
