“…With the continuous expansion of the modern CPPS, the design of a single centralized controller for various DERs have a chance to failure, since no other sources to control the system, the CPPS becomes unstable. The cost of implementing the centralized controller is very high [16]. This motivates to develop a multi-agent-based control for CPPS, which solves the cooperative optimization problem of various DERs integration into CPPS.…”

“…The communication effects like data loss, bad data, time-delay, etc., severely impacts the performance of the CPPS. The authors in [16][17] demonstrated the impact of time-varying communication delay on the stability of the practical large-scale CPPS in the transmission domain. The impact of asynchronous communication delays between the distributed phasor data concentrators for oscillation monitoring application of a wide-area power system is investigated in [18].…”

Cyber-Physical System (CPS) is a new kind of digital technology that increases its attention across academia, government, and industry sectors and covers a wide range of applications like agriculture, energy, medical, transportation, etc. The traditional power systems with physical equipment as a core element are more integrated with information and communication technology, which evolves into the Cyber-Physical Power System (CPPS). The CPPS consists of a physical system tightly integrated with cyber systems (control, computing, and communication functions) and allows the two-way flows of electricity and information for enabling smart grid technologies. Even though the digital technologies monitoring and controlling the electric power grid more efficiently and reliably, the power grid is vulnerable to cybersecurity risk and involves the complex interdependency between cyber and physical systems. Analyzing and resolving the problems in CPPS needs the modelling methods and systematic investigation of a complex interaction between cyber and physical systems. The conventional way of modelling, simulation, and analysis involves the separation of physical domain and cyber domain, which is not suitable for the modern CPPS. Therefore, an integrated framework needed to analyze the practical scenario of the unification of physical and cyber systems. A comprehensive review of different modelling, simulation, and analysis methods and different types of cyber-attacks, cybersecurity measures for modern CPPS is explored in this paper. A review of different types of cyber-attack detection and mitigation control schemes for the practical power system is presented in this paper. The status of the research in CPPS around the world and a new path for recommendations and research directions for the researchers working in the CPPS are finally presented.

“…The system is modeled considering the most detailed models available in DIgSILENT to represent power converters, synchronous generators, automatic voltage regulators, power system stabilizers, and turbine-governor systems. Damping controllers based on identified models obtained from simulation software were also studied in [32] and [34]- [36].…”

This work presents a hierarchical control strategy to improve the stability of electrical networks with significant converter-interfaced generation (CIG). Due to the lack of inertia of CIG systems, these networks can undergo a high rate of change of frequency, compromising the frequency stability. In a first level control, a local controller based on the virtual synchronous generator (VSG) concept is used to emulate inertia and provide short-term frequency regulation. However, the inclusion of significant VSG units can have a negative impact on the damping of inter-area oscillations. Therefore, in a second level control, a centralized controller is proposed to damp these low-frequency electromechanical oscillations affected by VSGs. Several practical issues such as the identification of a system model for the control design, the compensation of communication delays, and the discrete-time implementation of the controller are particularly analyzed. The introduced supplementary controls allow increasing the penetration of renewable energy sources without jeopardizing the frequency and small-signal stability. Eigenvalue analysis and nonlinear hybrid simulations combining DIgSILENT and Python are performed to validate the proposed control strategy.

“…Low‐frequency oscillation in the range of 0.1–3 Hz is rooted in generator mechanical modes that can endanger the rotor angle stability. So, a lead–lag power system stabiliser (PSS) is used to improve the system stability margin [1]. In spite of the good performance of the lead–lag stabiliser, it has favourable performance in the limited frequency range.…”
