One of the main characteristics of Smart Grids is self healing. This means that the grid should rapidly detects, analyzes, acts and restores for system instabilities. Controlled islanding is one of the techniques used to mitigate these system instabilities. System islanding is often considered as the final stage of power system defense plans. The goal is to preserve stable areas of the faulted power...
A decentralized coordinated control is researched based on multi-agent structure for transient stability improvement of large-scale power system in this paper. First, a multi-agent system (MAS) model is structured based on the wide-area measurement system (WAMS), which consists of both upper and lower level agents. The upper level coordinated agents are mainly responsible for coordinating and controlling...
Real-time Dynamics Monitoring System(RDMS) is applicable to monitor the dynamic behaviors of large region grid, such as low-frequency oscillation, short-circuit, frequency fluctuation, etc. For the perturbation in power systems occurs incidentally, it's difficult to collect enough cases for an complete test on RDMS, which may lead to potential risks of outage. So it's necessary to study more efficient...
This paper presents a network-based simulator for protective relaying algorithms. The simulator is based on the client-server paradigm. The simulator which consists of server-side relaying algorithm modules and the user interface provides the network-based environment to simulate a variety of protective relaying algorithms. It is developed by using open-source development tools and model-based design...
