To solve defects of the traditional Z-source topology, an enhanced three-level neutral-point-clamped quasi-Z-source inverter (3L NPC QZSI) topology is proposed in the paper. New topology combines the advantages of three-level neutral-point-clamped inverter with the advantages of quasi-z-source network. Compared with traditional topology, new topology can effectively enhance inverter boost capability, reduce the capacitor voltage stress and suppress start-up shock current. All the conclusion mentioned above have been confirmed by simulations and experiment.

This article mainly studies combustion instability. It analyzed the basic composition of the combustion chamber and gas turbine and the principle of combustion instability. In order to detect the abnormality of the combustion chamber pressure, the paper proposed a model based on the combination of Principal Component Analysis (PCA), Mind Evolutionary Algorithm (MEA) and Back Propagation Neural Network (BPNN). The model uses Pearson's rule and PCA to preprocess the data. Then it optimizes the back propagation neural network through the global optimization capability of MEA to obtain the optimal prediction curve. At last, the paper introduced similarity and set an early warning threshold to detect the limit alarm. After verification on the simulation platform of combined-cycle gas and steam turbine power plants and import real data for simulation, the results showed that the PCA-MEA-BPNN algorithm can handle non-linear problems well and detect abnormal combustion and issue an alarm.

There are a large number of power quality problems with large-capacity dedicated line users of the power grid. The monitoring data of power quality presents a large number of irregular characteristics. The signal samples obtained directly by measuring the signals contain a lot of complicated and useless information, and cannot be used for the type identification of special load power quality. Regarding this problem, this paper proposes a method for identifying the type of power quality disturbances with special loads based on S transform and support vector machine (SVM). Simulation and actual data experiments show that the method can accurately identify, and it is of great significance for grasping the features of power quality, as well as useful for the supervision, analysis and management of power quality.

Virtual power plants (VPPs) are defined as an aggregator of different types of energy resources and flexibility, coordinated by VPP owner through a smart control system. A correct establishment of a VPP will result in reduced electricity costs for the consumers within the VPP. One of the key aspect of VPP’s success is the consumer engagement in order to manage their flexibilities effectively. Gamification is an efficient way of learning and engagement, which can efficiently change the behavior of consumers towards participating in programs provided by VPPs for energy cost reduction. In this paper, a gamification-based approach for consumer engagement is proposed and a methodology based on Fogg’s behavior model and Kim’s model on player types is developed to examine the suitability of available gamification applications for energy saving/efficiency in the context of a VPP. Seven gamification applications are analyzed and evaluated based on the developed methodology and the results are provided.

A Hybrid Short-Term Load Forecasting Model Based on Sparse Attention Mechanism 基于稀疏注意机制的混合短期负荷预测模型

In the electricity market environment, an efficient and accurate load forecasting model plays a vital role in the operation and dispatch of the power grid system. However, the deep learning method represented by the recurrent neural network is difficult to capture the effective features of mixed time pattern sequences, and there is a problem of important information loss when the sequence is too long. To solve this problem, we propose a short-term load forecasting model of TCN (temporal convolutional network)-GRU (gated recurrent unit) based on the sparse attention mechanism. This model utilizes the sparse attention GRU network to capture the node features of different time patterns and highlight their importance and then uses TCN's causal dilated convolution operations to extract long-term temporal features of the sequence. Finally, the proposed model integrates two captured feature information to complete the load forecast. Taking the public data set of a certain area in Australia and the load data of a certain area in Shanghai, China as examples, we compare this model with the typical model respectively. The results show that the proposed model has higher prediction accuracy and model robustness.
在电力市场环境下,高效、准确的负荷预测模型对电网系统的运行和调度起着至关重要的作用。然而,以递归神经网络为代表的深度学习方法难以捕捉混合时间模式序列的有效特征,且当序列过长时存在重要信息丢失的问题。为了解决这一问题,我们提出了基于稀疏注意机制的TCN (temporal convolutional network)-GRU(门控循环单元)短期负荷预测模型。该模型利用稀疏关注GRU网络捕捉不同时间模式的节点特征并突出其重要性,然后利用TCN的因果展开卷积运算提取序列的长期时间特征。最后,该模型将两个捕获的特征信息整合在一起,完成负荷预测。以澳大利亚某地区的公共数据集和中国上海某地区的负荷数据为例,分别与典型模型进行比较。结果表明,该模型具有较高的预测精度和鲁棒性。

The fault characteristics of the small current grounding system are not obvious when the fault occurs. Currently, it is hard to accurately select and locate the ground fault in the small current grounding system. Therefore, in this paper, a scheme of fault grounding line selection and location is proposed based on the characteristic of the zero-sequence current matrix. As the zero-sequence current phase always lags behind the zero-sequence voltage when the amplitude of zero-sequence current increases. Based on this, we developed a State Matrix S. It can effectively reflect the degree of each region that is affected by the fault. Based on the State Matrix S, we can draw out the regional fault state value through a formula we created to quantify the influence of fault. Fault line selection and ground fault location can be accurately measured by calculating and comparing the regional fault state value of each region. The scheme proposed in this paper applies to a variety of the small current grounding system. The effectiveness and reliability of this scheme have been amply demonstrated through PSCAD/EMTDC simulations and experiments.
故障发生时,小电流接地系统的故障特征不明显。目前,小电流接地系统接地故障的准确选择和定位比较困难。因此,本文提出了一种基于零序电流矩阵特性的故障接地选线和定位方案。由于当零序电流幅值增大时,零序电流相位总是滞后于零序电压。在此基础上,我们建立了状态矩阵s,它能有效地反映各区域受故障影响的程度。在状态矩阵S的基础上,我们可以通过我们创建的公式来量化故障的影响,从而得出区域故障状态值。通过计算和比较各区域的区域故障状态值,可以准确地测量出故障选线和接地故障定位。本文提出的方案适用于各种小电流接地系统。通过PSCAD/EMTDC仿真和实验,充分证明了该方案的有效性和可靠性。

The 12kV drop-out fuse pre-arc time-current characteristic test is an important method to verify the quality of the fuse and the reliability of the fuse breaking. This paper summarizes the technical requirements of domestic and foreign test standards, combines test experience, analyzes the impact of test methods on product performance parameter test results, and gives test technical solutions and test standards. The results show that the reading value of the test current is the effective value of the full waveform of the test current, the expected current value is controlled within the range of -5% to + 5% of the target current value, and the test error meets the pre-arc time-current characteristic detection requirements; during the test process The current should be reasonably compensated according to the current attenuation to ensure that the current attenuation rate is less than 10%. The research results are a summary of the pre-arc time-current characteristic test schemes and standards for 12kV drop-out fuses, and have important practical guiding significance for improving the quality level of distribution fuses.
12kV熄火熔断器弧前时间-电流特性试验是检验熔断器质量和熔断可靠性的重要手段。本文总结了国内外试验标准的技术要求,结合试验经验,分析了试验方法对产品性能参数试验结果的影响,给出了试验技术解决方案和试验标准。结果表明:测试电流的读取值为测试电流全波形的有效值,期望电流值控制在目标电流值的-5% ~ + 5%范围内,测试误差满足弧前时间-电流特性检测要求;在测试过程中,应根据电流衰减情况合理补偿电流,保证电流衰减率小于10%。研究成果总结了12kV熄火熔断器弧前时间-电流特性试验方案和标准,对提高配电熔断器质量水平具有重要的实际指导意义。
