Due to increasing demand on adequate dynamic load modeling, aggregation algorithms for induction and synchronous motors are proposed in the literature for cases that the same types of motors are connected to a common bus. However, one problem remains unsolved: how to perform load aggregation with upstream motors if both induction and synchronous motors are(More)
A directional sensor network is composed of many directional sensor nodes. Unlike conventional omni-directional sensors that always have an omni-angle of sensing range, directional sensors may have a limited angle of sensing range due to technical constraints or cost considerations. Area coverage is still an essential issue in a directional sensor network.(More)
Conventionally, in wireless power transfer (WPT) system, all resonators are set at exactly the same resonant frequency, which is considered as the optimal operation condition to achieve resonant coupling. However, at over-coupled region, frequency split issue occurs, as a result, the frequency for the maximum power is not coincident with the frequency for(More)
Wireless power transfer is a very promising technology in industrial applications. This paper analyzes the difference of LC parallel and series resonant topology in wireless power transfer. With the three coils model as example, on the transmitter side, it is proven that the voltage source in parallel resonant mode is interchangeable with the current source(More)
This paper extends the highly versatile method, known as the Plug-in Modeling Technique(PMT) to several FACTS devices, such as TCSC, SVC and TCPS, and a new type of generator, i.e. DFIG type of wind turbine generator. A case study to illustrated the FACTS and DFIG type of wind turbine is demonstrated.
