In this paper, based on the basic feature and its engineering calculation method of photovoltaic power, the mathematical model of PV power was established. The voltage oriented control (VOC) was applied in connecting to the power grid. In the context of PSCAD/EMTDC, a PV grid-connected system model was constructed and simulation research was conducted. The results demonstrated the main harmonic source of the photovoltaic grid-connected system and measures to restrain the harmonics effectively were summarized, which provided theoretical basis and engineering foundation for improving the power quality of a photovoltaic grid-connected system.

The rapid development of economic society puts forward higher requirements for English talents. Currently, the English education in colleges and universities stays in the onefold teaching mode, the teaching efficiency is low, and the students do not have good English comprehensive application ability. Based on the network multimedia technology, college English teaching mode of constructivism can be very good to solve the above problems, improve the efficiency of student learning, and active the construction of knowledge. This paper discusses the teaching mode of constructivism based on the multimedia and network technology, and proposes a new teaching method and mode.

The essence of 3D model retrieval is to classify and to sort. An algorithm based on neural network is proposed in this paper. After pretreatment, six projection viewpoints are selected to project the 3D model in order to generate six two-dimensional images. Then the images are transformed by Fourier Transform to obtain the vector features. Finally, the dimension of vector is compressed to input into neural network to retrieve. The advantage of neural network is to provide an interface between the system and the users. Users can retrieve more than one times if not satisfied. Proved by experiments, the algorithm can get better performance and satisfactory efficiency.

As the environment pollution is becoming more and more serious and the nature resources have been running out, the electric vehicle plays a more important role in the world. However, it is well known that the inadequate driving range is the inherent limitation that hinders electric vehicles widely. This paper aims to analysis and optimize the low speed electric vehicle material by using hybrid materials and optimizing the size of frame.

Image dehazing algorithm based on dark channel prior has been proved to be effective, but it cannot still guarantee accurate transmission. To solve this problem, we firstly propose a more reasonable estimation of atmospheric light, because bias in the atmospheric light estimation will cause an inaccurate transmission. Secondly, we improve the estimation of transmission in bright area so as to alleviate color distortion. After image recovery, we carry out denoising to improve the image quality. Finally, we use a blind image quality assessment method based on property of Human Visual System, and the experimental results show that this improved algorithm is more effective.
