In view of the influence of smart meter's reliability on smart grid, this paper presents a reliability prediction optimal model of smart meter. Firstly, establish the reliability model of smart meter based on the component stress method. Secondly, combined with the field data, smart meter prediction model is established based on new Weibull distribution parameter method and point estimation method...
Abstract-Dynamic optimization techniques such as dynamic voltage and frequency scaling (DVFS), power gating (PG) and thread migration are widely used in current multi-core processor platforms to boost performance, lower power and improve energy efficiency. To obtain the best optimization results, an important issue is to predict the performance of each thread quantitatively. In this paper, a separated...
To track the wide range of operating points of fast time-varying processes, a novel multiple model off-line predictive control algorithm is presented. The proposed method is a combination of multiple model strategy and predictive control. Firstly, we locally describe the original nonlinear system around an operating point employing linear time varying (LTV) model. Then the offline model predictive...
With the development of power industry, the proportion of Large-scale Generating Unit in power grid is getting bigger and bigger. The control object of the generating unit is a complicated manufacturing process which is strong-coupling, time-variable, nonlinear and big-lag. It is difficult to establish accurate model when the parameters of control object is uncertainty because of all disturbances,...
