Power quality disturbance(PQD) identification is the premise of power system fault analysis and processing. This study proposed a PQD identification method based on an improved fully convolutional network. It combines the representation ability of fully convolutional networks for data and the memory function of long short-term memory networks for time series data. First of all, the one-dimensional voltage signal is directly used as input into the FCN-LSTM serial model. After the FCN layer is processed by convolution, batch normalization, and global average pooling, it enters the LSTM layer to extract timing features, and finally determines the type of disturbance. Numerical experiments show that the method had high recognition rates for PQD and strong anti-noise interference ability, which is superior to a single convolutional neural network and LSTM network. The engineering data verify the feasibility of this method in the field of power grid fault diagnosis and analysis.

State Grid has released SG-CIM v4.5 as the basis for information sharing in the design and development of business applications. In this paper, an SG-CIM verification method is proposed. The logical model of business applications is transformed into a unified standard format and compared with the SG-CIM based on schema comparison to check the conformance with the SG-CIM. The quality of conformance is reflected in scores. The SG-CIM verification method is also validated with model data from a business system. SG-CIM verification lays the foundation for information exchange among business applications and ensures that business applications can share and exchange business data which comply with the SG-CIM, thereby breaking the information barriers among business applications and facilitating information interactions among business applications.

The advancement of a battery management system is notably decisive in small unmanned aircraft. One of its roles is estimating the State of Charge. Where the State of Charge is used to determine the battery capacity to preventing over-discharging and under-discharging processes. Moreover, this is very important in maintaining the security of the electrical energy distribution process to the onboard electrical system on small-scale unmanned aircraft. In this study, the 5000 mAh Lithium Polymer battery modelling based on the Electrical Equivalent Circuit methods and the EKF algorithm was used to estimate the SoC, because this method provides low complexity and low computational requirements. The estimation results show that the MAE and RSME with this method showed less than 1%. Moreover, determination of noise is added to implemented in real conditions, where the results show that the SoC estimation is adaptive to a given disturbance.

With the transformation of energy structure in China, the proportion of clean energy in the power system will further increase. The demand for flexible power supply in the system will grow visibly to ensure the safe and stable operation of the power system. As important flexible modulation resources, Pumped storage and electrochemical energy storage are complementary to each other in modulation performance, therefore, the joint participation of the two in frequency modulation is considered as a way to achieve complementary advantages. In line with the modulation characteristics and the principles of pumped storage and electrochemical energy storage, in this paper, a mathematical model of the two kinds of energy storage jointly participating in power grid frequency modulation based on virtual droop control strategy was established, and a simulation model on the control strategy of the joint frequency modulation was built in MATLAB/ Simulink. Taking a power grid in North China as an example, this paper simulated the improvement effect of frequency modulation performance under step load disturbance and continuous load disturbance, and verified the effectiveness of the model.

In order to solve an EMI issue which caused the uplink transmission from ground-fixed balise to on-board BTM antenna abnormal, an installing metal shielding plate measure was proposed through a series of simulation analysis. The BTM antenna and reference loop model was built as uplink transmission system, a car body on rail segment model was built as environmental condition, a simplified jamming loop model was built as source of interference EM field. The metal plate shielding effectiveness was optimized between EMI suppression effect and the BTM antenna performance degradation. Simulation and optimization result was verified by actual measurement, and the EMI issue was resolved. The measure can be used to protect BTM antenna against interference EM environment for engineering application.

Forecasting the load power in the solar plant is essential to maximize the available profit from the solar plant. This project develops the Gated Recurrent Unit (GRU) based deep learning machine to predict hourly load power in a solar plant. The weather parameters influence the load power, which affects the user behavior of load power. All selected features and the target variable are collected for more than one year in a solar plant installed in Taiwan. The collected data are utilized in the simulation of the Gated Recurrent Unit to evaluate the accuracy and performance in predicting the short-term load power. The performances of GRU are compared with the RNN model by statistical benchmarks. The experiment results prove that the GRU-based deep learning machine could achieve higher accuracy and better stability in predicting the short-term load power in solar plants.

Photovoltaic plants do not intrinsically have natural inertia. Natural inertia in power systems comes from the stored kinetic energy of the rotating parts of a synchronous machine. The inertia of the synchronous machine keeps the power system from being too sensitive to disturbances in the system. When a disturbance in the power system occurs that affects the frequency stability of the power system, the primary response of the synchronous machines is to expend the stored energy in the rotors. This immediate response of synchronous machines is emulated in PV plants by taking advantage of the fast response of power electronic devices. This study aims to propose a new control strategy using a modified VSM model in DIgSILENT PowerFactory as the base model. The base model is modified to include a fast frequency response component directly embedded into the inputs of the control system. The proposed control strategy utilizes the deviation of the frequency from the nominal value and applies it directly to the reference power and mechanical time constant.

China's development path under “urban-rural dualism” has caused a number of socio-economic issues, which forces the state to gradually change its city-prioritized policy towards “urban-rural integration”. This paper firstly sorts out the evolution process of China's urban-rural relationship. Then taking four Prefecture-level cities as cases, this paper compares different modes of urban-rural interaction. Performances of urban-urban-rural interactions are also measured. Finally, on the basis of historical combing and empirical research, it explores the major contributors of these differences in case areas and promotion of ideas and strategies of urban-rural integration and its ways of energy use.
