The structure of microgrids and the models considered have a significant impact on the planning and operational outcomes of micro grids. Additionally, micro grids encompass various models of primary equipment, including wind, solar, diesel, and storage, while the demand-side response mechanisms are continually being refined. This necessitates the construction of diverse load types, thereby increasing the complexity of micro grid planning and highlighting the need for further research into microgrid planning models. This paper presents various typical mathematical models for microgrids, employs spectral clustering algorithms to obtain representative scenarios, and constructs a unified planning model for microgrids. Furthermore, it elucidates the model adjustment methods under different planning objectives and conducts case analyses of microgrid planning issues. © 2024 IEEE.

Dynamic Quantized control of Fuzzy Semi-Markov Jump Systems With Fading Channels: An Improved Event-Triggered Mechanism

IEEE Transactions on Systems, Man, and Cybernetics: Systems 2025年第5期55卷 3519-3531页

This article focuses on the dynamic quantized control for Takagi-Sugeno fuzzy semi-Markov jump systems (T-S FSMJSs) under fading channels and deception attacks, employing an improved event-triggered mechanism (ETM) strategy. Specifically, a more generalized semi-Markov process (SMP) that is governed by a higher-level deterministic switching signal (HLDSS) is addressed. A novel dynamic ETM is skillfully developed based on the information of quantization and two internal dynamic adjusting variables to further enhance the network bandwidth utilization. The dual asynchronous phenomenon between the plant and controller (asynchronous modes and mismatched premise variables) is addressed. This implies that the designed controller is not required to share the same membership functions and modes as the plant, establishing a more rational structure. The hidden semi-Markov model (HSMM) is attained to characterize the stochastic varying channel fading amplitudes. The Lyapunov function incorporating mode and fuzzy information is constructed to establish sufficient criteria ensuring the strictly dissipative performance and mean-square exponential stability (MSES) of the resulting closed-loop systems, and a new security fuzzy dual asynchronous controller is then developed. Finally, the efficacy and applicability of the results are demonstrated through numerical and practical examples. © 2025 IEEE.

Isolated Bridgeless PFC Converter Based on Active-Clamped SEPIC

引用

CPSS Transactions on Power Electronics and Applications 2022年第3期7卷 239-250页

作者： Wu, Deliang Sondharangalla, Madhura Ayyanar, Rajapandian School of Mechatronic Engineering and Automation Shanghai University Shanghai China School of Electrical Computer and Energy Engineering Arizona State University Arizona United States

A new isolated bridgeless PFC converter based on active-clamped SEPIC is proposed. Compared to conventional active-clamped SEPIC PFC converter, the proposed converter reduces conduction loss by removing two diodes in the line current path, while preserving the advantages of the active-clamped SEPIC such as zero-voltage switching (ZVS) and active voltage clamp for all the high frequency switches, soft turn-off of the out-put diodes and well damped control-to-input-current response. In addition, the peak voltage stress on the output diode is inherently clamped by the center-tapped transformer configuration. Experimental results from a 3.3 kW prototype verified the operation of the converter and demonstrated peak efficiency of 97.26% with 140 kHz switching frequency. The power density of the single-phase PFC module is 101 W/in3. © 2017 CPSS.

Equivalent input disturbance-based load frequency control for smart grid with air conditioning loads

引用

Science China(Information Sciences) 2022年第2期65卷 106-123页

Integrating intermittent wind power into power systems results in low or zero inertia, threatening their frequency stability. To accommodate intermittent generations, the demand response(DR) is introduced, and air conditioning loads(ACs) account for an increasing proportion of all loads. The replacement of traditional generators with wind turbines and the ACs user uncertainties produce parameter uncertainties. This paper aims to construct an equivalent input disturbance(EID)-based load frequency control(LFC) strategy for the power system by considering wind power and ACs. First, an open-loop model is constructed for the LFC scheme with parameter uncertainties. Then, the parameter uncertainties and external disturbance are lumped into a fictitious disturbance, which is estimated using an EID *** incorporating the estimation of disturbance into the control input, the disturbance-rejection performance is achieved. Next, the Lyapunov theory is used to derive the two linear-matrix-inequality-based asymptotic stability criteria. A design algorithm is developed for the EID-based LFC scheme by exploiting an overall performance evaluation index. Finally, simulation results for the single-area and two-area LFC schemes show that, compared with the existing approaches, the method presented realizes the better disturbance rejection and higher robustness against parameter uncertainties, wind power fluctuation, and tie-line power ***, its robustness to time delays is verified.

At high velocity flight, the infrared imaging system encounters significant aero-optical disturbances due to the uneven gas flow around the aircraft's forward section and the elevated temperatures of the optical dome. In the simulation study of aero-optical effects, hydrodynamic calculations of the gas flow field and optical dome are required. This paper examines the utilization of the solid-fluid coupling approach in simulating aero-optical phenomena from the perspective of fluid dynamics computations. This paper undertakes the geometric modelling of the airflow environment and optical dome of a blunt-nose front-window flight vehicle. Utilizing ICEM, the mesh generation for both the gaseous flow domain and the solid optical dome is executed. Subsequently, Fluent software facilitates the performance of hydrodynamic simulations, concurrently extracting vital parameters from both the flow field and the optical dome. The method in this paper can be used in the calculation and analysis of aero-optical effects of high-speed flight vehicles. © 2024 IEEE.

The environmental-friendly gas-insulated ring network cabinet is referred to as an environment-friendly cabinet. The high-voltage circuit parts of the environment-friendly cabinet are mainly composed of conductors, VCB, and the knife-brake type three-station disconnector. The insulating support parts are composed of insulating board, insulating arms, and so on. The grounding parts consist of a metal shell and grounding contacts. Simulation of the electrostatic field of the environment-friendly cabinet is during the condition of isolation fracture. Simulation results show that there are local high electric fields on the metal surfaces of the support for VCB, moving contacts, and static contacts, which are 20.7SkV /mm, 10.06kV/mm, and 7.41kV/mm, respectively. Adding a thin metal sheet to the support for the VCB or filling the gap with silicone rubber will reduce the electric field to 4.S1kV/mm and 4.1kV/mm, respectively. The metal shielding structures are installed on both sides of the moving contact and the static contact of the disconnector, and the surface electric field intensity is reduced to 5.25kV/mm and 5.18kV/mm respectively on the disconnector during the state of isolation fracture. The optimized environment-friendly cabinet was tested for power-frequency voltage-withstand test and partial discharge. The results showed that the optimized environment-friendly cabinet passed the power-frequency voltage-withstand test and the magnitude of partial discharge was better than the initial scheme, which verified the feasibility of the optimization. © 2024 IEEE.
