Every luxury businesss future growth relies heavily on marketing strategies and product optimization for high-end goods. Understanding the causes and mechanisms behind how the symbolic worth of luxury brands is formed is crucial for customers who want to maintain composure and create a rational consumption mindset, as well as for society as a whole. This paper uses case study and comparative analysis methods to analyze the Current Situation in the Luxury Industry. This paper finds the characteristics of Goyard Target Customers are rich/wealthy and crave exclusiveness/ secretiveness. In addition, this paper proposes the current problem identified by Maison Goyard. Based on the analysis, this paper proposes that the marketing strategy optimization of Maison Goyard includes: Implementing more advertising and more exposure to the market; Celebrity endorsements (such as Instagram/ Facebook) to attract new customers; Collaborations with other luxury brands/ New Limited Editions to increase popularity in the mass market; Start on E-commerce to face the new generations/ millennials. This article explores Maison Goyards current difficulties and optimization objectives, which have contributed to the brands promotion and will continue to do so in the future.

“…In addition, the dynamic features of the DC-DC converter with the neural network can be realized excellent dynamic characteristics, compared with the conventional methods [74]. Without any prior knowledge, NN controllers can handle the problem, showing good performance under rapidly varying [75,76]. Recently, genetic algorithms [77][78][79][80], pattern swarm optimization (PSO) [81][82][83], ant colony MPPT [84,85], grey wolf MPPT [86], hybrid models such as hybrid particle swarm optimization and salp swarm optimization algorithm [87], and the MPPT control of wind turbines by using ANN-PSO wind speed estimator [88] have been proposed but each of the above-mentioned techniques has complexity levels based on their applications.…”

In the field of wind turbine performance optimization, many techniques are employed to track the maximum power point (MPPT), one of the most commonly used MPPT algorithms is the perturb and observe technique (PO) because of its ease of implementation. However, the main disadvantage of this method is the lack of accuracy due to fluctuations around the maximum power point. In contrast, MPPT control employing neural networks proved to be an effective solution, in terms of accuracy. The contribution of this work is to propose a hybrid maximum power point tracking control using two types of MPPT control: neural network control (NNC) and the perturbation and observe method (PO), thus the PO method can offer better performance. Furthermore, this study aims to provide a comparison of the hybrid method with each algorithm 𝑃𝑂 and NNC. At the resulting duty cycle of the 2 methods, we applied the combination operation. A DC-DC boost converter is subjected to the hybrid MPPT control. This converter is part of a wind energy conversion system employing a permanent magnet synchronous generator (PMSG). The chain is modeled using MATLAB/Simulink software. The effectiveness of the controller is tested at varying wind speeds. In terms of the Integral time absolute error (ITAE), using the PO technique, the ITAE is 9.72. But, if we apply the suggested technique, it is smaller at 4.55. The corresponding simulation results show that the proposed hybrid method performs best compared to the PO method. Simulation results ensure the performance of the proposed hybrid MPPT control.

“…At the end of 2020, the global installed capacity of it has exceeded 700 GW (Global Wind Energy Council, 2021). But the wind power is connected to the grid through a back-to-back full-power pulse width modulation (PWM) converter and generally works in the maximum power point tracking (MPPT) mode (Gaied et al, 2022). The rotor speed of wind power generator is decoupled from the grid frequency unlike traditional synchronous generators (SGs) (Fan et al, 2021).…”

With high penetration of wind power, the apparent inertia of power systems is decreased, which seriously affects the safety and stability of the system frequency. Therefore, a novel sliding mode frequency control (SMFC) scheme is proposed for the wind turbines participating in frequency regulation support (FRS) in power systems, which can significantly improve the dynamic characteristics of the system frequency. At first, a power system frequency response model considering wind turbines participation in FRS is derived. In this model, the load disturbance, wind power disturbance and synchronous generator frequency regulation dynamics are combined as a lumped disturbance. Then, the design of the proposed SMFC scheme, which combines the super-twisting sliding-mode disturbance observer (STSMDO) with the super-twisting sliding-mode frequency controller (STSMFC), is introduced. The proposed STSMFC has ability to tune the system dynamics easily by choosing suitable sliding surface matrix via eigenvalue assignment method or optimal sliding manifold design. In such a frequency control scheme, the stability of the system frequency is guaranteed by the STSMFC, whereas the STSMDO is employed to estimate the lumped disturbance. Finally, numerical simulations verify the effectiveness and superiority of the proposed SMFC scheme.
