Abstract ：
Bi-directional DC-AC converters are widely used in the field of electric vehicle-to-grid. However, the inductance of the grid-side interface filter is affected by the length of the grid connection and the power level, which presents nonlinear characteristics. This poses challenges for high-performance grid waveform control. In this paper, a modeling method for bi-directional DC-AC grid-connected converters based on type-II T-S fuzzy models is proposed, and the corresponding type-II T-S fuzzy control strategy is designed to address the parameter uncertainty and non-linearity issues. Simulation results show that type-II T-S fuzzy control offers superior control performance and better current waveform quality compared to type-I T-S fuzzy control under uncertainty parameter conditions. The effectiveness of the proposed strategy is further validated through a 1 kW prototype of a bi-directional DC-AC converter.

Abstract ：
Battery state-of-health (SOH) estimation is an effective approach to evaluate battery reliability and reduce maintenance costs for battery-based backup power supply systems. This paper proposes a novel SOH estimation method for batteries, which only uses the response characteristics of load surges and is, therefore, non-destructive to the estimated battery and its system. The discrete wavelet transform (DWT) method based on multi-resolution analysis (MRA) is used for wavelet energy features extraction, and the fuzzy cerebellar model neural network (FCMNN) is introduced to design the battery SOH estimator. The response voltage signals to load surges are used in the training and detection process of the FCMNN. Compared to conventional methods, the proposed method only exploits characteristics of online response signals to the inrush currents rather than injecting interference signals into the battery. The effectiveness of the proposed method is validated by detailed simulation analysis and experiments.

Abstract ：
Advanced wind power prediction technique plays an essential role in the stable operation of the grid with largescale grid integration of wind power. Most research focuses on distance-based static classification where the subjective nature of initial center selection increases the uncertainty of the prediction. And the data classification on a daily basis neglects the potentially significant climate changes at smaller time scales. To address these issues, the improved snake optimization-long short-term memory (ISO-LSTM) model with Gaussian mixture model (GMM) clustering is proposed to forecast wind power from an adaptive perspective. By exploiting the merits of the probabilistic classification, the K-means optimized GMM clustering enables an appropriate feature modelling for substantial climate changes at smaller time scales. Then the ISO algorithm exhibits higher search accuracy and is better suited for finding hyperparameter combinations for LSTM neural networks. The data from the National Aeronautics and Space Administration (NASA) of the US is used to validate the effectiveness of the proposed method. Compared to the traditional K-means clustering, the K-means optimized GMM clustering has increased accuracy by 2.63 %. Simultaneously, with the adoption of the enhanced ISO algorithm, the accuracy further increases by 7.27 %. Different existing models have also been tested; it shows that the proposed model demonstrates higher prediction accuracy.

Abstract ：
The optimal capacity of energy storage facilities is a cornerstone for the investment and low-carbon operation of integrated energy systems (IESs). However, the intermittence of renewable energy and the different operating characteristics of facilities present challenges to IES configuration. Therefore, a two-stage decision-making framework is developed to optimize the capacity of facilities for six schemes comprised of battery energy storage systems and hydrogen energy storage systems. The objectives considered are to minimize the levelized cost of electricity (LCOE), power abandonment rate (PAR) and maximize self-sufficiency rate (SSR) simultaneously. In the first stage, each scheme is solved using NSGA-II. In the second stage, the weights of objective function are determined by entropy weight method, while the optimal individual is selected from the Pareto solutions by the technique for order preference by similarity to ideal solution approach. Life models of battery, fuel cell, and electrolyzer are introduced to quantify device replacement costs. Meanwhile, carbon trading mechanisms and time-of-use tariffs are considered to assess environmental and economic benefits. The results show that the hydrogen-electric coupling scheme demonstrated superior performance, with LCOE, SSR, and PAR of 0.6416 ¥/kWh, 48.9 %, and 1.96 %, respectively, and the hydrogen storage tank is closely related to LCOE and PAR. © 2024 Elsevier Ltd

Abstract ：
The use of renewable energy for power generation and hydrogen production can improve the economic efficiency of multi-energy coupled microgrids, as well as the capacity of renewable energy to be consumed. In this paper, a deep interactive dispatching strategy for multi-energy coupled microgrid is proposed. Firstly, a multi-energy coupled microgrid structure is built, incorporating an electric hydrogen production system on the load side. An economic analysis of the deep interaction of multiple energy sources is then conducted based on electricity to hydrogen energy consumption for dispatching decisions and supporting strategies. Simulation is also carried out for the verification of the deep interactive dispatching model. It proves the rationality and feasibility of the proposed model for scheduling energy use within a multi-energy system. © 2023 IEEE.

Abstract ：
Virtual synchronous generator (VSG) control technology can simulate the output characteristics of a synchronous generator. VSG can effectively solve the problem that the inertia and damping support capacity of the grid decreases after a large-scale distributed energy resource is connected to the grid. However, the selection of its control parameters is more complex. The unsuitable control parameters have a great influence on the grid-connection stability of the inverter. In order to solve this problem, the acceleration factor is linearly changed based on Particle Swarm Optimization (PSO) algorithm, and it is used for the optimization calculation of VSG control parameters. The traditional VSG control method and the optimized VSG control method with different optimization algorithms were compared and analyzed by Simulink. The simulation results show the effectiveness and superiority of the improved particle swarm optimization algorithm. © The Institution of Engineering & Technology 2023.

Abstract ：
When the parameters of each module in the input series output parallel（ISOP）dual active bridge DC-DC（DAB）converter system are different，the system has over-voltage and over-current caused by unbalanced transmission power，which may damage the device in serious cases. In addition，current stress and the dynamic performance of converters should also be considered during operation. To address these issues，this paper proposes a voltage balance control scheme combined with current stress optimization based on dual phase shift. The current stress and transmission power model of the converter under dual phase shift is analyzed. And then the phase shift ratio for current stress optimization is obtained by the KKT condition method. On the basis of current stress optimization，a voltage balance control method is proposed. The outer phase shift ratio expression is deduced through the transmission power model，and the voltage balance component and dynamic transmission power are introduced to achieve input voltage balance and output voltage stability and improve dynamic performance. Finally，a dual- module ISOP- DAB experimental platform is built，and comparative experiments are carried out to verify The effectiveness of the control method in this paper is verified by the comparative experiments. © 2023 Science Press.
