Authors: Sheng Xin 
Published: March 2020

Abstract
The innovation of remanufacturing technology is an effective way to keep the cost advantage of reproducts, and patent licensing facilitates the production of reproducts by independent remanufacturers. Considering people’s different preferences for reproducts and new products, we first construct an evolutionary game composed of original manufacturers and independent remanufacturers based on the theory and method of evolutionary game. Next, we study the evolutionary stable point and the influence factors of patent licensing and remanufacturing technology innovation strategy selection by Jacobian matrix. Finally, the model conclusion is verified by numerical analysis. The research shows that when the innovation level of remanufacturing technology is within a certain threshold, independent remanufacturers ultimately choose the technology innovation strategy, while original manufacturers always ultimately choose the patent licensing strategy and it is not affected by the innovation level of remanufacturing technology.

Published: March 2020

Abstract
A novel electrochemical capacitor electrode based on Ce/Ni-MOFs was prepared. During this process, we introduced hydrothermal method. However improper reaction conditions would cause the collapse of crystal structure which will do harm to the performance of the electrode. We explored the option reaction conditions including temperature and end urance time. Under the option condition, we performed a series of electrochemical testing and surface characterizations to explore and electrochemical performance and cycle life. We obtain the Ce/Ni-MOF electrode with the capacitance of 584F/g and the retention of 95.5% after 1000 cycles of charging and discharging test. This indicate that Ce/Ni-MOFs might be a promising supercapacitor electrode for future use.

Abstract
The purpose of this study was to improve the utilization efficiency of solar energy, and accelerate the innovation and development of solar flywheel energy storage control system, so as to enhance the utilization value of new energy. Firstly, the definition and working method of flywheel energy storage control system were described, and the characteristics of flywheel energy storage control system were introduced in detail. Secondly, the concept and working principle of solar flywheel energy storage control system were introduced, and the principle and calculation method of perturbation and observation method (P&O) were described in detail. Finally, the improved P&O based on particle swarm optimization (PSO) algorithm was described in detail, and its principle and operation methods were explained. The research results show that the biggest characteristic of flywheel energy storage device is that it has no pollution to the environment, the energy stored per unit area is large, and the efficiency of converting it into electric energy is very high, which can be used for a long time. The working property of solar energy storage system is the introduction, maintenance, and output of electric energy. In order to obtain the best tracking data, the flywheel energy storage control system must control the disturbance amplitude and time accurately and make a comprehensive choice. The P&O improved by PSO algorithm is applied to the flywheel energy storage control system, and the experience time to reach the maximum efficiency position is relatively shortened. When the system’s derived power reaches the balance, the variation of wave shape in the improved dynamic observation method is also relatively reduced.

Authors: Zhuo Lan , Han Hongzu , Zhao Hongtu , Xun Shen 
Published: March 2020

Abstract
An internal coupled-feed microstrip RFID tag antenna for UHF band is presented in this article. To achieve a compact size, the orthogonal cross-slot is etched on the radiation patch, reducing antenna size and providing feeding space for L-shaped feedline. In order to meet the metal-mountable advantage and the low-profile size requirement, the ends of L-shaped feedline are connected with ground through metal-via. By optimizing the size of L-shaped feedline, the expected input impedance of the proposed tag antenna can be obtained easily. Moreover, the target band of circular polarization (CP) can be covered by optimizing the length of slits, which is embedded in the four corners of the radiation patch. The measured 3-dB Power Reflection Coefficient (PRC) bandwidth of the proposed tag antenna is 98 MHz (from 840 to 938 MHz), and its 3-dB axial-ratio (AR) bandwidth is 7 MHz (from 920 to 927 MHz). Further test results demonstrate that the tag antenna can provide better gain and reading range when mounted on a metal plate.

Published: March 2020

Abstract
Bus load base is small and volatile, so it is difficult to predict ultra-short-term load. Distributed photovoltaic power supply connected to bus power supply area further increases the uncertainty of bus load and directly affects the prediction accuracy. Aiming at the ultra-short-term load forecasting problem of bus with photovoltaic power supply under complex weather conditions, a method of bus ultra-short-term load forecasting based on feature selection and XGBoost is proposed. Firstly, a high-dimensional feature set is constructed with various influencing factors, and the XGBoost predictor is trained with the original feature set in the typical meteorological day historical data such as rainy and sunny days, and the degree of response between the bus load and the multi-factor is determined during the training process. Then, the MAPE value is used as the evaluation index. Forward search is used to select features to determine the optimal feature subsets of different typical weather day predictors. Finally, according to the selected optimal feature subsets, the optimal XGBoost prediction model for different weather days are established to predict the bus output of different weather days. Experiments on bus data with distributed photovoltaic in a certain area show that the new prediction model has higher prediction accuracy.

Abstract
With the development of big data and artificial intelligence, the applications of smart grid have received extensive attention. Specifically, accurate power system load forecasting plays an important role in the safety and stability of the power system production scheduling process. Due to the limitations of traditional load forecasting methods in dealing with large scale nonlinear time series data, in this paper, we proposed an Attention-BiLSTM (Attention based Bidirectional Long Short-Term Memory, Attention-BiLSTM) network to do the accurate short-term power load forecasting. This model is based on BiLSTM recurrent neural network which has high robustness on time series data modeling, and the Attention mechanism which can highlight the key features playing key roles in load forecasting in input data. The verification experiments with real data in a certain area show that the proposed model outperforms other models in terms of prediction accuracy and algorithm robustness.

Published: March 2020

Abstract
Microgrid can effectively improve the ability of power grid to absorb distributed energy. The new structure with power electronic transformer (PET) as the core of energy management is the new development direction of microgrid. A micro grid control strategy for coordinated operation of PET and energy storage is proposed. The interface converter of energy storage adopts constant voltage and constant frequency control to maintain the stability of voltage and frequency of micro grid. The low-voltage AC interface of PET connected to micro grid integrates the control of virtual synchronous generator to adjust the mechanical reference power according to the state of energy storage. Energy storage responds to the power fluctuation in microgrid rapidly, while PET maintains the stability of energy storage capacity through two-way power regulation and ensures the “flexible” exchange of power between microgrid and grid. Because energy storage and PET are controlled as voltage source interface at the same time, when one of them fails, the microgrid can still operate smoothly. Under this control strategy, microgrid operation can ensure the maximum efficiency of intermittent distributed energy utilization, and improve the stability, reliability and user friendliness of microgrid operation. Simulation and hardware in the loop hardware in the loop experiment results verify the correctness and effectiveness of the proposed control strategy.

Published: March 2020

Abstract
Optimization and upgrade of energy consumption and friendly-developing eco-environment play a core part in Beijing-Tianjin-Hebei’s coordinated development strategy. Energy consumption structure interacts with environment. This paper selects coal,oil and gas consumption in Beijing-Tianjin-Hebei as energy structure variable waste gas, gas and solids discharge as environment variable to establish a Vector Auto-Regression (VAR) model, which is used to study their Johansen Cointegration test, and their interaction via impulse response function and variance decomposition. The result shows an outstanding cointegration between the both, with a lagging effect on three wastes discharge, and coal, oil and gas consumption contributing variably to three wastes discharge. A balanced development between Beijing-Tianjin-Hebei’s energy consumption and environment may be achieved by making full use of such lagging effect and contribution extent and real-time evaluation & adjustment of exterior conditions.
