Tension leg platform (TLP) is a kind of offshore structures for oil or gas exploration in deep-water which has its special feature as partly compliant and partly rigid. Extended tension leg platform (ETLP) is the third generation of TLP which made an improvement on the basis of typical TLP structure. Extended structure is the most notable feature of ETLP which could increase the distance of groups...
This paper presents a novel analytical method in studying the capability of an energy storage system (ESS) installed in a power system to damp power system oscillations. The proposed method is based on the well-know equal-area criterion and linearized small-signal stability analysis. In the paper, the proposed method is presented generally for the analysis of damping a power oscillation along a transmission...
For studying the damping effect of power system controllers, such as PSS and FACTS stabilizers, Phillips-Heffron model has been used extensively and many analytical conclusions and design methods have been developed on the basis of Phillips-Heffron model. Hence, in order to carry out systematical investigation on the damping effect of ESS controllers on power system oscillations, this paper established...
The paper establishes the linear Phillips-Heffron model of a power system installed with flywheel energy storage (FES) based on a doubly-fed induction machine (DFIM) and demonstrates the application of the model in analysis the damping effect of the flywheel energy storage and designing a power system stabilizer based on the FES to improve power system oscillation stability. The case of a single-machine...
