An Intelligent Method for Fault Diagnosis in Photovoltaic Array

A new intelligent method is proposed to detect faults in the photovoltaic (PV) array. Usually, there is an obvious temperature difference between the fault PV module and the normal PV module. So, the temperature information of the PV modules is utilized to locate the fault in the PV array firstly. Then, the Artificial Neural Network (ANN) is applied to diagnosis the type of the fault. The current of maximum power point (



), the voltage of maximum power point (



) and the temperature of the PV modules are input parameters of the ANN. The output of the ANNunit is the result of the fault detection. Basic tests have been carried out in the simulated environment under both normal and fault conditions. The simulation results show that the outputs of the ANN are almost consistent with the expected value. It can be verified that the proposed method based on ANN can not only find the location of the fault but also determine the type of the fault.

Comparison of LOLE and EUE-Based Wind Power Capacity Credits by Probabilistic Production Simulation

To mitigate the global climate change and environmental issues, wind power generation is growing at a startling pace around the world. The wind power capacity credit can be used to measure the contribution of wind power resource to the capacity adequacy of a power system, thus plays an important role in development of wind power resources and expansion planning of power systems. Using the probabilistic production simulation technology, wind power capacity credits based on the capacity adequacy indexes LOLE and EUE are investigated and compared in this paper. The theoretical analysis and numerical simulation show that non-smoothness presents in variation of the LOLE index with load, while variation of the EUE index with load displays a good smoothness. This will lead to a difference in the EUE-based and the LOLE-based wind power capacity credits. In addition, the wind power capacity credits based on the LOLE index is non-monotonic for relatively small installed capacity of wind power.

Modeling and Simulation of Electricity Markets under Different Environmental Policies

Renewable energy quota obligation has been enforced in many countries to mitigate greenhouse gas emissions and promote renewable energy. To fulfill the quota obligations, many countries have adopted environmental policies such as carbon tax (CT) and feed-in tariff (FIT) in their electricity sectors. This paper aims to examine the impacts of different environmental policies on the electricity market competition and the social welfare. For this purpose, Cournot equilibrium models for electricity wholesale market competition are developed taking into account the CT and the FIT policies. The nonlinear complementarity approach is employed to solve these equilibrium problems. In addition, an environmental policy that combines the carbon tax and the feed-in tariff (CT&FIT) is also proposed in this paper. Numerical simulations are presented to assess the performances of different environmental policies. Some practically meaningful conclusions are derived.

Overload Risk Assessment in Grid-Connected Induction Wind Power System

Aiming at the new uncertainties brought by wind farms connected directly into power grid, a novel approach to calculate overload risk in grid-connected induction wind power system is proposed.

Furthermore, the severity function is applied to describe the impact of line flow fluctuations. Finally, the overload risk index is quantified and is treated as an indicator of power system security. Simulation results of the modified 5-bus system confirm the effectiveness of the proposed method.

Simulation Research on the Effect of Thermocline on Underwater Sound Propagation

The thermocline has an important influence on sound propagation or underwater acoustic detection in shallow water. The beam-displacement ray-mode theory is used to analyze the effect of thermocline on underwater sound propagation. The peculiarity of this method is that the boundary effects on the sound field can be expressed by the equivalent boundary reflection coefficient. An improved new method for computing the upper boundary reflection coefficient in the theory is proposed based on the generalized phase integral eigen function and an univocal formulation of upper boundary reflection coefficient is deduced. An ocean environment model of thermocline is established. The effect of thermocline’s depth, thickness and intensity on sound transmission loss is discussed. The research result shows that thermocline has an important effect on sound transmission loss. It is of practical guiding significance in sonar detection and underwater warfare.

Numerical Modeling for Venus Atmosphere Based on AFES (Atmospheric GCM for the Earth Simulator)

In order to elucidate phenomena of Venus atmosphere, an atmospheric general circulation model (AGCM) for Venus is being developed on the basis of AFES (AGCM For the Earth Simulator). As a first step toward high resolution numerical simulation with realistic physical processes, we investigate unstable modes on the condition of super-rotation by nonlinear numerical simulation with simplified physical processes. At initial state zonal super-rotation is assumed to exist. We use the relaxation forcing of the meridional temperature gradient to maintain the zonal flow. In the time evolution of this experimental setting, baroclinic modes grow in the cloud layer with small static stability. The structures of unstable modes are similar to those obtained in the linear stability analysis. We discuss resolution dependency of the results.

Modeling and Simulation of Partial Shaded PV Modules

Partial shading instances are very common in photovoltaic (PV) systems. The mismatch losses and hot spot effects caused by partial shading can not only affect the output power of solar system, but also can bring security and reliability problems. A mathematical model reflecting the output electrical characteristics of the partial shading PV module is put forward in this paper. Compared with the traditional model, it is able to show the variation of the output electrical characteristics of the PV module by adjusting the irradiance, temperature and the area of partial shading. The model is used to analyze the power losses of the partial shaded PV model with different number of bypass diodes. The simulation results show that a PV model under partial shading with 6 bypass diodes is the best configuration to minimize the mismatch power loss.

Simulation and Analysis of Space Object Visibility Based on Space-Based Optics Surveillance

The visibility analysis model of space object based on space-based optics surveillance is derived from constraints including the earth masking, the earth shadow, the sunlight and the field of view. According to the orbit distribution character of space objects, we analyzed the visibility of some typical space objects using three groups of observation platform which has low, middle and high orbits respectively. Three helpful results are derived from the simulation experiments. Firstly, the visibility of low orbit space objects is poor, the total time of visible arcs is less than 1 hour in the 24 hours observation. Secondly, there is extremely little influence made by restraints of the earth masking and the earth shadow for the visibility of middle and high orbit space objects. Finally, the visibility of space objects using middle or high orbit observation platform is beneficial than using low orbit observation platform.

By using the man-in-loop simulation experiment modeling method which the gunner takes participate in, this article analyses distribution principles of aiming-point, building the gunner’s aiming precision model. Moreover, through exploring differences of gunner’s individual skills on the basis of the mentioned work, gunners’ operation skills distribution model including aiming-point judgement capability difference model and manipulation capability difference model is built. Moreover, by applying this model in operation simulation, the fidelity of operation simulation can be enhanced.

Multi-aircraft Cooperative Target Allocation in BVR Air Combat Using Cultural-Genetic Algorithm

According to the characteristics of BVR (Beyond Visual Range) air combat, a mathematical model of multi-aircraft cooperative target allocation problem was built. Also a Cultural-Genetic Algorithm is proposed to solve this problem, which integrates cultural algorithm and genetic algorithm effectively. Based on the framework of Cultural Algorithm, Genetic Algorithm is selected as the evolutionary algorithm of population space. The knowledge of reasonable allocation plans is extracted from population space and stored in a belief space, which will influence the selection and mutation operation of Genetic Algorithm to make the optimization fast and accurate. Simulation results on typical application instances show that this algorithm is more efficient in performance than traditional Genetic Algorithm.

Secure and Semantic Repository for Weapon Models in the Cloud

Simulation-based weapons analysis requires significant efforts to represent the complex structure and dynamics of weapon systems on the computer. A model repository can help model developers to save their development costs and time by utilizing predefined and already validated weapon models. In this paper, we introduce OpenREM (Open REpository for weapon Models) which has been developed to store weapon models in the cloud data storages. OpenREM provides a semantic search service to reuse semantically similar models, despite of their structural and textual differences. OpenREM also prevents and detects possibly security probes, and employs an intrusion tolerant mechanism to be able to survive through security threats.

Finite Element Analysis of Mice Tibia under Impact Loading

Fracture is one of most common injuries in the clinical diagnosis, mainly existed by the kind of stress fracture. With the fast development in sports area, not only the olds but also more and more young athletes may suffer the disease, usually happening under an impact. Currently there are only limited tests to predict the fracture such as BMD (bone mineral density) testing or biopsies of microdamage, but none of them was specific enough. Under such circumstance, this study will try the FEM (finite element method) to find out the process of impact fracture. A free-fall device was set up and a geometry model of mice tibia was created based on a real one. The results show that under the condition of no fracturethe maximum stresses occurred at two crooks, 1/3 below the knee joint of the tibia and 1/3 above the ankle joint, which were the same with clinical diagnosis statistic. In addition, an experiment was conducted with the same device, and the results were matched with the FEM simulation. Therefore this model of simulation was well suitable for the study on impact fracture, and would help in future fracture prediction.
