Through the research on modeling and SOC estimation of the battery in the isolated Micro-grid, the behavior characteristics of the battery was analyzed under normal and stable operation, and further more, the condition was determined to guarantee the stability of system based on SOC of the battery. Under the premise of stable operation, a control strategy was put forward based on SOC to adjust the...
With the national energy structure adjustment accelerating the development of the scale of large grid-connected wind farm, large-scale and high degree of concentration grid-connected wind farm has a great impact on power adjustment control, power quality, and grid stability. This paper has studied the impact of large-scale and grid-connected wind farm on voltage sag propagation characteristics, voltage...
Based on the perspective of demand motive of foreign exchange reserve, this paper constructed the measurement model of moderate scale of foreign exchange reserve based on multi-level demand and selected the actual data of China for measurement. Results have shown that the moderate interval of China's foreign exchange reserve was between 900 billion, and its excess scale was about...
Considering nonlinear, severe disturbance and time-varying characteristics of large belt conveyor system, the nonlinear mechanism model is analyzed in the paper. The sample data set is obtained from the experimental belt conveyor system by the finite elements method, and the predictive model of belt conveyor system based on the least square support vector machine is built up to improve the prediction...
In this paper, we introduce a systematic power analysis framework for SoC designs using bottom-up power modeling integrated with top-down power estimation. Four power analysis tools have been realized: (1) PowerBrick, a power characterization tool to construct power libraries for standard cell library and memory compiler, (2) PowerMixer, an RTL/gate-level power estimator for large logic design, (3)...
To get maximum gas well productivity, this paper analyzes the influence of different fracture parameters on gas well performance and gets the qualitative principle of fracture distribution of fracture horizontal well with multi-fractures by the tight gas reservoir fracture horizontal well flow model. For quantitatively describing fracture parameter design (mainly fracture size and distribution), fuzzy...
Independent board directors have a compelling obligation for listed companies' illegal activities, and their performance has a direct effect on the listed companies' illegal activities. The incentives to independent directors are the main influencing factors in their responsibility fulfillment. From the perspective of independent directors, this paper studies the correlation between the allowance-incentives...
Although the probabilistic model checking tool called PRISM had been applied in many communication systems, such as wireless local area network, Bluetooth, and ZigBee, the technique is not used in a controller area network (CAN). In this paper, we use PRISM to model the mechanism of priority messages for CAN because the mechanism lets CAN as leader in serial communication for automobile and industry...
Higher temperature induced by higher power density results in higher cost, lower performance and lower reliability. The thermal effects become important issues of today's VLSI design. In this paper, we adopt a RC-based thermal model to perform the steady-state and transient thermal analysis for a tri-core SoC system. The power information is generated from the ESL power estimation. The results show...
The 3-layer workflow scheduling model consist of front layer, outside scheduling layer and inside scheduling layer, it can describe the task scheduling more clearly than conventional models. This paper mainly discusses the improved Dijkstra algorithm with multi-precondition, which is the core of this model, converts the classical Dijkstra algorithm into an useful way to calculate the shortest path...
