Guo Li, Fang Xiang, Wu Shuang
Under the background of energy Internet, the application of a series of new technologies and new products has made the development of power grids more rapid. In the contemporary context, the power grid is gradually getting rid of the traditional focus on scale development and focusing on improving efficiency and efficiency. Therefore, it is necessary to establish an integrated evaluation system to evaluate the progress status of the power grid for the development status of the power grid. Based on the energy Internet background, this paper establishes a set of index systems suitable for the development status of the power grid and combines the entropy method with fuzzy comprehensive evaluation to establish an evaluation model. The example shows the validity of the model proposed in this paper.

Accurate and precise prediction of power output plays a great significance in power system industry, as it provides the basic outlooks and views for making future decisions in power system planning and operation. This paper used monthly and annual dataset of output power and solar irradiance from a stand-alone solar system to compare nonlinear autoregressive neural network (NARNET) and nonlinear autoregressive with External (Exogenous) input neural network algorithms in predicting (short term and long term prediction) the output power from photovoltaic (PV) system. During the execution of prediction, The Levenberg-Marquardt method was adopted and used for training. Comparison results reveals that NARNET and NARX neural network are both suitable for performing PV output power prediction, but NARX was found to be more accurate. NARNET best prediction result was achieved with MSE (Mean Square Errors) equal to 1.6153 and coefficient R equals to 0.47643 while for annual NARNET prediction model, the MSE and R were found to be equals to 0.84891 and 0.82244. For NARX monthly prediction model, the MSE and R were equal to 0.99206 and 0.53094 while for the case of NARX annual prediction model, the MSE and R were 0.8008 and 0.85248 respectively. The lower the MSE indicates few errors and the more R is close to unity indicates the better correlation and great relation between actual and predicted values.
准确准确的输出功率预测在电力系统工业中具有重要意义,它为电力系统规划和运行的未来决策提供了基本的展望和观点。本文利用独立太阳能系统的月度和年度输出功率和太阳辐照度数据集,比较了非线性自回归神经网络(NARNET)和非线性自回归与外部(外生)输入神经网络算法在光伏(PV)系统输出功率预测(短期和长期预测)中的应用。在预测执行过程中,采用Levenberg-Marquardt方法进行训练。对比结果表明,NARNET和NARX神经网络均适用于光伏发电输出功率预测,但NARX神经网络更准确。当MSE(均方误差)为1.6153,R系数为0.47643时,NARNET预测模型的最佳预测结果为MSE为0.84891,R为0.82244。对于NARX月度预测模型,MSE和R分别为0.99206和0.53094;对于NARX年度预测模型,MSE和R分别为0.8008和0.85248。MSE越低,误差越小,R越接近1,表明预测值与实测值相关性越好,关联度越大。

Adhesive Handwritten Digit Recognition Algorithm Based on Improved Convolutional Neural Network 基于改进卷积神经网络的手写体数字识别算法
Junyi Tang, Ping Han, Dong Liu
Traditional machine learning algorithms are susceptible to many factors in the recognition of handwritten adhesion numbers, such as different people's digital writing habits, different degrees of adhesion, and low image quality, which could lead to lower digital recognition accuracy. To solve these problems, an improved convolutional neural network algorithm for handwritten adhesion digital recognition is proposed in this paper. First, an improved convolutional neural network model is provided for the large number of adhesion in handwritten digital pictures. Multilevel feature extraction is performed on the experimental images using convolution kernels of different scales, and then, the feature frame filtering algorithm is optimized to improve the recognition accuracy of handwritten adhesion numbers while enhancing the robustness of the neural network to background noise. The experimental results show that the average recognition accuracy of the improved convolution model on the experimental data set is 94%. The proposed algorithm reduces the parameter size with ensuring high recognition accuracy, and improves the recognition efficiency of the system, which is better than most state-of-the-art algorithms.
传统的机器学习算法在识别手写附着力数字时容易受到很多因素的影响,比如不同人的数字书写习惯、不同程度的附着力、图像质量不高等,这些都会导致数字识别精度降低。针对这些问题,本文提出了一种改进的卷积神经网络手写体粘连数字识别算法。首先,针对手写体数字图像中存在的大量粘附现象,提出了一种改进的卷积神经网络模型。利用不同尺度的卷积核对实验图像进行多级特征提取,然后对特征帧滤波算法进行优化,在提高手写体粘附数识别精度的同时增强神经网络对背景噪声的鲁棒性。实验结果表明,改进的卷积模型在实验数据集上的平均识别准确率为94%。该算法在保证较高识别精度的前提下减小了参数大小,提高了系统的识别效率,优于目前大多数算法。

Ni Li, Guozhu Ma, Hongxia Sun, Ting Zhao
Under the situation of rapid increase in business, IMS Technology is introduced into the power exchange network. The deep integration of business and control saves the physical space of exchange in volume. The data from different business terminals are gathered on the unified platform by adopting the consistent SIP exchange protocol. It is often encountered that the business concurrent demand is greater than the system capacity, resulting in the failure of the session process execution. In this paper, we propose a solution based on business characteristics to deal with session conflicts, explore IMS business triggering mechanism and process, and find its limitations. According to the different characteristics of business triggering, set up the business conflict resolution scheme, which can predict the concurrent conflict of multiple sessions before it occurs. It start the conflict prevention scheme on demand in time, and use the exchange resources on demand on the premise of meeting the business needs to the maximum. The research method proposed in this paper is to provide a better solution to practical problems in the era of power grid information explosion.

Fountain Codes-based Two-way Multiply-and-Forward Relaying in Rayleigh Fading Channels 基于喷泉码的瑞利衰落信道双向复用转发
Shengkai Xu, Dazhuan Xu
In this paper, a three stages fountain codes-based two-way multiply-and-forward (MF) relaying system over the Rayleigh flat fading channel is proposed, where two source nodes communicate with each other through a relay node and all nodes work on half-duplex and time-division mode. The signals during all three stages thoroughly in the proposed system are analyzed and the equivalent point-to-point channel model is further provided. Using the method developed for fountain codes optimization, this paper finally puts forth an optimization model for the MF-two-way relay network (MF-TWRN) with fountain codes. Simulation results show that our optimized degree distribution can provide outstanding bit-error-rate (BER) performance for the MF-TWRN.

In facility infrastructure companies, factories, hospitals and towns without their own generators, transformers are important step-up and step-down devices in power transmission systems. Transformer users often face challenges including how to reduce human maintenance of transformer maintenance, transformer temperature, obtaining real-time operating data, remotely monitoring transformers, or data collection and analysis. However, this study develops a low cost system for monitoring the status of remote distribution transformers using GSM technology. The system performance was modelled and simulated at different transformer loads. The system was able to activate the cooling system case of over temperature, switch of the transformer in case the problem still persists and sent a message to the user via short message service (SMS). This research realizes intelligent monitoring at a low price, which is an important value and contribution.

In order to satisfy the flight safety early warning requirements of UAV to the greatest extent and improve the safety and reliability of UAV operating in mixed airspace, with reference to flight interval standards, a cylinder static protection zone model of UAV is constructed to detect the flight conflict trend and near midair collision trend between UAV and intruder, and then a dynamic collision avoidance zone modeling method based on emergency collision avoidance trajectory of UAV in three-dimensional space is proposed to delineat the dynamic collision avoidance zone for detecting the collision trend of two-aircrafts. The simulation results show the effectiveness of the method.
为了最大程度地满足无人机飞行安全预警需求,提高无人机在混合空域运行的安全性和可靠性,参考飞行间隔标准,构建无人机圆柱体静态保护区模型,检测无人机与入侵者的飞行冲突趋势和近半空碰撞趋势。在此基础上,提出了一种基于无人机三维空间应急避碰轨迹的动态避碰区域建模方法,对动态避碰区域进行划分,用于检测两机碰撞趋势。仿真结果表明了该方法的有效性。
