It has become a general consensus that smart grid is one of the most important technical fields for big data technology application. Power network dispatching and planning is fundamental to power industry development and construction, however, massive power data is still manually filled in, dispatching method and planning design method relies heavily on experience and single data source. This paper firstly described smart grid big data and its characteristics. Secondly, the overall big data business requirements and application scenarios in energy area were summarized. Afterwards, big data requirements and enhancements throughout the entire power network planning process were analyzed. Finally, practical research projects were demonstrated, and the technological framework on big data in power network planning was presented.

State estimation is the foundation of energy management system. The innovation graph state estimation has an advantage over traditional state estimation in identifying bad data. We infer the distribution function of innovation difference and set the threshold in certain false drop rate, which provides the theoretical basis for identifying bad data in mathematics. The range of acceptable measuring error depends on the accuracy of corresponding measuring instrument. This method reduces the false detecting rate and the loss detecting rate. The function of innovation graph technique to identify bad data is improved. The method proposed in this paper is verified in a simulation with bad data based on IEEE 14-bus system and the result show that the method is effective.

With the establishment of the Emission Control Areas(ECA) of China, and the huge demand of the One Belt One Road (OBOR) strategy of intermodal transport, container intermodal transport will be rapid development in the future. Meanwhile, the air pollution problem is increasingly serious, optimizing the container intermodal transport in port, reducing emissions, and improving operation efficiency, which, is an urgent problem to the port operator. In this study, three models are proposed to deal with the intermodal transport problem of container terminal in ECA. Firstly, a dynamic berth allocation problem with ship emissions consideration (EDBAP), based on an application of shore power is modeled. Then, truck dispatching problem (TDP) is presented, the third one is ship and train scheduling problem (STSP). Mixed integer non-linear programming (MINLP) models are developed for these problems, heuristic algorithm to solve these problems. Experimental results demonstrate that the intermodal transport problem of container terminal, reflected by the proposed models, is competent to reduce emissions, while simultaneously retaining the service level, thus improve operation efficiency in intermodal transport of container terminal.

The poor performance of MHD ARS at low frequency has depressed its accuracy and application range. A preliminary study on the magnetohydrodynamic (MHD) angular rate sensor combing Coriolis effect (C-MHD ARS) is made to achieve the low-frequency bandwidth expansion. Physical model of C-MHD ARS is given, and then the physical design with an MHD pump is described. The numerical simulation and experiment are illustrated based on the designed device. The simulation results demonstrate that the Coriolis effect is induced at low frequency and can accelerate the relative velocity. Furthermore, the experiment results confirm the improvement of the C-MHD ARS at low frequency. This study can offer a preliminary understanding of C-MHD ARS design and help us give further error analysis on the sensor.

Action recognition is still a challenging problem. In order to catch effective compact representation of the action sequences, the discriminative dictionaries could be learned by sparse coding. But sparse coding is needed in both the training and testing phases of the classifier framework. And it is also time consuming for the adoption of 1-norm sparsity constraint on the representation coefficients in most dictionary learning (DL) methods. Dictionary pair learning (DPL) learns a synthesis dictionary and an analysis dictionary jointly. Compared with those DL approaches, the using of DPL method may not only effectively reduce the time consuming during the phases of training and testing, but also result in very competitive recognition ratio. On the other hand, the way of compressed learning can lead to learning with randomly projected data instead of original data. Thus compressed learning could greatly cut down on both the requirement of memory storage and running time due to the effective reduction of data dimensions through random projection. In this paper, Combined with compressed learning, DPL in compressed space are explored for the action recognition. By the experiments on various public action datasets, it has been shown that DPL in compressed space can achieves very competitive accuracy, while it is significantly faster in phases of both training and testing, which indicate the efficiency of the proposed algorithm for action recognition.

Pedestrian detection is an important topic in object detection. Compared with other object detectors, YOLOv2 achieves high accuracy and fast speed for general object detection, however it degrades accuracy when detecting crowed pedestrians. In this paper, combining with the skip structure of FCN, we tailor the YOLOv2 network to improve the accuracy in detecting small pedestrians which appear in groups in underground coal mine. In this way, we propose two modified versions of YOLOv2 which are YWSSv1 and YWSSv2. Compared with YOLOv2, YWSSv1 slightly improves 0.1 mAP but keeps the same fast speed. YWSSv2 significantly gains 12 mAP higher than YOLOv2 but sacrifices its speed at just 5 FPS.

The high-speed camera is an imaging device that records a particular transient state or all of the high-speed processes. It can accurately record the transient process of the high-speed target in real time and thus allow us to achieve the purpose of analysis of high-speed process through the slow motion playback. So the high-speed camera becomes an important tool for the study of the transient phenomena. This paper presents the development of a high-speed imaging system, which was build based upon a CMOS (Complementary Metal Oxide Semiconductor) image sensor and a high density FPGA (Field Programmable Gate Array) and USB 3.0 (Universal Serial Bus 3.0). In this paper, the design methodology and the electronics system architecture are briefly discussed. Besides, the designs and implements are particularly depicted. Finally the experimental verification shows the correlated results. The system has the advantage of high frame rate, high resolution, high performance and flexibility.

Capacitor-switching operation can be used to measure network harmonic impedance. Via the transient components of voltage and current after capacitor switching, the harmonic impedance of PCC (Point of Common Coupling) can be calculated. To improve measurement accuracy, the TLS-ESPRIT algorithm is introduced in this paper to filter out noise and fundamental components in voltage and current signals. Via time domain simulations, the advantages of the proposed method in the ability of noise interference resistance and measurement accuracy, are verified compared with the Prony algorithm based method.

This paper shows the design of a self-powered wireless digital sun sensor (including magnetometer). The information of satellite attitude and magnetic field intensity can be transferred to the attitude determination and control system (ADCS) through Bluetooth. Four solar cells in parallel connection and a super capacitor make sure that the sun sensor can work both in sunshine and shadow areas. The sun sensor meets the needs of microsatellite, which has small volume (30mm×30mm×12.5mm), low power (<50mW), large field of view (120°) and high precision (0.5°).
