Cyberphysical paradigm of multiagent systems for smart microgrids
Published in Rodolfo Dufo-López, Jaroslaw Krzywanski, Jai Singh, Emerging Developments in the Power and Energy Industry, 2019
In real production environments, communication failures in communication channels can significantly degrade the reliability of the cooperative control of distributed energy resources in distribution networks, which may cause very serious problems for both system operation and control in a power grid and can interrupt the wide area damping control of power systems.
A Comprehensive Study of Wide-Area Damping Controller Requirements Through Real-Time Evaluation with Operational Uncertainties in Modern Power Systems
Published in IETE Journal of Research, 2022
In modern interconnected power systems, low-frequency electromechanical oscillations constitute a significant problem. The stable, secure, and reliable operation of the system is predominantly associated with decreasing these oscillations. Low-frequency inter-area oscillations (0.2–1.0 Hz) are the reason for major blackouts in the power systems. Inter-area oscillations modes are not effectively damped out by conventional methods such as power system stabilizers. PSSs primarily provide the damping to generators and damp out the mainly intra-plant modes of oscillations (2.0–3.0 Hz) and local-plant modes of oscillations (1.0–2.0 Hz). Poorly damped inter-area modes of oscillations affect the system stability. So, effectively damping out the low-frequency inter-area mode of oscillations, a wide-area damping control system is used in the modern interconnected power system to enhance the system stability, reliability, security, and power transfer capacity. Modern power systems are divided into two parts: physical power systems and cyber power systems. The communication system plays an important role in WAMS-based WADCS to transfer the wide-area signals because controller performance is dependent on fast and quality information signal flow. Delayed signals decrease the WADCS performance and affect the system’s stability and security.
