Economic Performance and Emission Reduction of Supply Chains in Different Power Structures: Perspective of Sustainable Investment
Energies, 2018Co-Authors: Xiutian Shi, Ciwei Dong, Xiaoli Zhang, Subin WenAbstract:Environmental issues have increasingly received attention in both industry and academia. Many firms have started to make sustainable investments, such as adopting the pollution-abatement technologies, to reduce carbon emissions. To investigate the impacts of the sustainable investment on firms’ profit and emission reduction, we consider supply chains with uncertain demand in different Power Structures. Specifically, we examine the sustainable investment problem in three supply chain Power Structures, i.e., manufacturer Stackelberg (MS) Power Structure, vertical Nash (VN) Power Structure and retailer Stackelberg (RS) Power Structure. We first derive the optimal decisions for both the retailer and manufacturer in each Power Structure. Then, by comparing the results in the three Power Structures, we find that the manufacturer gets benefits from making the sustainable investment, especially in unequal Power Structures. When the average market size is large (small) enough, both of the supply chain members obtain more profits in the MS (RS) Power Structure. From an environmental perspective, we find that the emission reduction is more significant in sequential games (i.e., MS and RS Power Structures) than that in a simultaneous game (i.e., VN Power Structure). In addition, we conduct some numerical studies and discuss more managerial insights in the paper.

Bidirectional Wireless Power Transfer System with Wireless Control for Electrical Vehicle
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019Co-Authors: Benoit Sarrazin, Paul Albouy, Alexis Derbey, Jean-paul Ferrieux, Gérard Meunier, Jean-luc SchanenAbstract:This paper presents a Bidirectional Wireless Power Transfer (BWPT) system, for medium speed charging Electrical Vehicle (EV), with Vehicle to Grid (V2G) capability. The studied system has 20 kW Power rating and allows an inter-coil distance between 17 and 25 cm with an offset direction x and y of 10 cm. The control of the converters has also wireless features. Efficiency results of the whole DC-DC Power Structure with the coupler are presented for several misalignments of the vehicle side. Finally, a way to improve the converters efficiency is proposed, using a dedicated control allowing working in full bridge synchronous rectifier mode, depending on the operating condition.

economic and environmental performance of fashion supply chain the joint effect of Power Structure and sustainable investment
Sustainability, 2017Co-Authors: Xiutian Shi, Yuan Qian, Ciwei DongAbstract:Fashion supply chain members now search for trade-offs between sustainable investment and the related incentives, such as savings on environmental taxes and gains in incremental demands. To evaluate the economic and environmental performance of sustainable investment from a Power perspective, we develop an analytical model to study a two-echelon sustainable supply chain consisting of one retailer and one manufacturer with three different Power Structures. We derive the optimal solutions for various cases associated with different supply chain Power Structures and sustainable investors. Though it is beneficial for both the manufacturer and retailer to make sustainable investment, they often utilize high Power to gain economic benefit with less sustainable investment. Interestingly, the follower with less supply chain Power has more incentive to make a sustainable effort to achieve a higher profit. The optimal amount of sustainable investment in the apparel manufacturer investment case is greater than that in the retailer investment case in most scenarios.

Power strategies for maximum control Structure of a wind energy conversion system with a synchronous machine
Renewable Energy, 2005Co-Authors: A Bouscayrol, P Delarue, Xavier GuillaudAbstract:Abstract The control of a wind energy conversion system can be decomposed into two parts: a local control depending on the Power Structure and a global control (strategy) deduced from global considerations. The local part ensures an efficient energy management of each component of the system. The local control Structure can be deduced from the Energetic Macroscopic Representation, which is a graphical description of the system according to action and reaction principle. Using inversion rules, the deduced control Structure is composed of a maximum of control operations and measurements. The global control part is independent of the Power Structure. This strategy part leads to achieve Power objectives (active and reactive Power targets) and system constraints (machine efficiency and DC bus limitation). Several strategies can be defined for the same system. These control decompositions are applied to a wind generation system composed of a permanent magnet synchronous generator and two three-phase converters. Simulation results are provided for a 600 kW wind energy conversion system.
