This paper presents a real-time simulation platform for smart grid applications. The developed platform is capable of simulating complex smart grid models with large numbers of high-speed switching devices at real time. Furthermore, an integrated approach is adopted to combine real-time simulations of communication systems and electric power systems together, which provides an effective approach to...
The introduction of communication systems to power system controllers have brought in another layer of complexity in their design and operation. In this paper a Plug-in Hybrid Electric Vehicle (PHEV) charging facility is studied. A linearized model of the facility is built including both the dc/dc and dc/ac converters of the Distributed Energy Resources (DER). In addition, a control strategy that...
This paper introduces a platform for real time simulation and its contribution towards smart grid related research, with focus on Plug-in Hybrid Electric Vehicles (PHEV) charging stations. The current system is able to simulate in real time key elements of a smart grid such as: high speed power electronics, distributed energy resources (DER), and communication networks. A description of the platform...
A compact 1:4 parallel phase shift power divider that provides equal power split to all four output ports and 900 phase difference from port 3/4 to port 2/5 over a large bandwidth is presented, which comprises two composite right/left handed(CRLH) transmission lines(TLs) in transformer, two CRLH TLs in output port 3 and port 4. The proposed CRLH power divider provides wide impedance bandwidth of 76%...
The dynamics of the local field neural networks have been studied extensively, and many good results have been obtained. It should be pointed out that, the global robust stability for the static neural networks with time-delays received very little attention despite its practical importance. Based on the fixed point theory, Lyapunov functional and differential inequality technique, a new criterion...
The dynamics of the local field neural networks have been studied extensively, and many good results have been obtained. It should be pointed out that, the global robust stability for the static neural networks with time-delays received very little attention despite its practical importance. In this paper, by using the topological degree theory M-matrix theory and the linear differential inequality...
This paper proposes a novel radio resource management scheme in the link adaptive WiMAX network and the hierarchical priority-queuing with weighted round-robin (HPWRR) scheduling algorithm for different traffic services. The radio resource management scheme can re-assign the burst profile and dynamically adjust the allocated bandwidth to the SSs to improve the resource utilization. Then, the HPWRR...
