In LLC resonant converters, the variable duty-cycle control is usually combined with a variable frequency control to widen the gain range, improve the light-load efficiency, or suppress the inrush current during start-up. However, a proper analytical model for the variable duty-cycle controlled LLC converter is still not available due to the complexity of operation modes and the nonlinearity of steady-state...
Demand side management (DSM) is an essential function to schedule and optimize the energy consumption in smart grids. One of the challenges of DSM is how to take the complex human behavior into consideration. In this paper, we apply a special population dynamic model to investigate the performance of DSM algorithms under human behavior effects. Specifically, we adapt the SISa (susceptible-infected-susceptible...
A custom-designed and well-monitored substation communication network (SCN) can maintain fast and reliable information transmission and lead to improved operation and management of a substation automation system (SAS). In order to achieve this goal, a traffic-flow model, including a port connection model, a traffic-flow source model, and a traffic-flow service model of an SCN is developed in this...
An important challenge regarding peer's trust valuation in peer-to-peer (P2P) networks is how to cope with such problems as dishonest feedbacks from malicious peers, collusions and complex strategic frauds, which cannot be effectively tackled by the existing solutions. Thus, a reputation-based distributed trust management model for P2P networks, named RATM for short, is proposed to quantify and evaluate...
The open, sharing and anonymous nature of peer-to-peer (P2P) network has offered opportunities and threats for the development of distributed computing technology. One feasible way to minimize threats is to establish the reputation-based global trust model. Previous work about the global trust model is almost based on the assumption that the peer with higher trust value will provide more honest feedbacks,...
