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...
A DFIG-based wind generator electromagnetic transient model is established on the RTDS platform in this paper. Stator flux oriented vector control scheme is adopted to achieve power decoupling control in the DFIG based wind model. In order to research the impact of the wind farm on the existing protection relay of the network, this paper establishes single machine electromagnetic dynamic equivalent...
Small capacity PV substation in power system analysis was considered as the load, but it is not right to the MW PV substation due to so many bulk capacities. In response to this question, the dynamic modeling and transient fault analysis of feeder in distribution system with MW PV substation is researched. The key of the PV modeling is to consider the dynamic behavior of power electronic circuit in...
Dynamic voltage stability analysis is mainly based on the time-domain solution of power system differential equations. The modeling of each power element has a great influence on the correctness and complexity of stability analyzing. It is a significant work to model appropriately for simplifying calculation and drawing out principal contradiction. Firstly, the dynamical mechanism of voltage stability...
Appropriate modeling of dynamic loads is of primary importance in voltage stability studies, especially increasing use of induction machines in both consumption and generation. This paper is mainly related to short-term voltage instability depending on time domain simulation. The actuality of voltage instability research is summarized, and the mechanisms of short- term voltage stability are explained...
