In order to enable the permanent magnet synchronous generator (PMSG)-based wind turbine (WT) capture more energy while providing fast frequency supports effectively during disturbances, this paper proposes a time-sharing coordinated control (TFCC) strategy. Firstly, rotor virtual inertia and DC-link are presented, new adaptive droop considering deviation is proposed. Secondly, novel TFCC strategy, which uses dead-band coordinate regulation priority of above three controls, With proposed...
As one of the new generation flexible AC transmission systems (FACTS) devices, interline power flow controller (IPFC) has significant advantage simultaneously regulating multiple lines. Nevertheless, how to choose appropriate location for IPFC converters not been discussed thoroughly. To solve this problem, paper proposes a novel method using entropy theory. clarify IPFC's impact on system flow, its operation mechanism and control strategies different types serial are discussed....
The development of wearable strain sensors for the human-machine interface has attracted considerable research interest. Most existing were incapable simultaneously detecting amplitudes and directions, they failed to fully record stretching vectors that occurred on body. Graphene graphene-derived materials have been utilized construct with excellent electrical sensitivities. Although growth techniques planar graphene vertical (VG) established, fabrication VG aligned in parallel within a...
Against the crippling assault of power grid, impact cyber attack on line-commutated converters based high voltage direct current (LCC-HVDC) system is investigated in this paper when false data injection (FDI) attacks its control loops. Based basic strategy LCC-HVDC, each HVDC mode FDI occurs, including rectifier side constant DC and supplementary damping control, inverter extinction control. Through theoretical analysis, it found that would limit transmission increase HVDC's reactive demand,...
Abstract Sunlight‐excitable orange or red persistent oxide phosphors with excellent performance are still in great need. Herein, an intense orange‐red Sr 3− x Ba SiO 5 :Eu 2+ ,Dy 3+ luminescence phosphor was successfully developed by a two‐step design strategy. The XRD patterns, photoluminescence excitation and emission spectra, the thermoluminescence spectra were investigated detail. By adding non‐equivalent trivalent rare earth co‐dopants to introduce foreign trapping centers, of Eu 3...
This paper proposes a joint limiting control strategy for suppressing DC fault current and arm in modular multilevel converter-based high-voltage direct (MMC-HVDC) systems, which includes two target-oriented controls. To limit the early stage, an equivalent converter (MMC) impedance is obtained, its high-frequency part reshaped by introducing virtual impedance, realized adjusting inserted submodules adaptively. Following analysis of MMC characteristics, investigated, with results showing...
The integration of large-scale renewable energy and power electronic devices into the grid, as well uneven distribution units loads, further increases risk transient instability at critical load centers. installation synchronous condensers (SCs) in grid can enhance its stability. Therefore, it is necessary to focus on siting sizing SCs, considering both economic safety factors. To address this issue, paper proposes a configuration method based full electromagnetic (EMT) simulation....
Abstract Waterflood conformance is a significant problem in the West Sak field of Alaska. Re-assembling Pre-Formed Particle Gels (RPPG) have been used to treat Void Space Conduits (VSC) and repair "short-circuited" waterflood. These VSC’s are typically formed by sand producing wormholes. Several dozen VSC solutions implemented since 2006, including molten wax, cement blends, pre-formed particle gels. To date, all faced with various limitations due low reservoir temperature poor...
China is taking initiative in energy transition to cope with the long-term controversy of its enormous consumption, aiming use less carbon. Wind power, especially offshore wind energy, has become a prevailing alternative due low carbon emissions, renewability, competitiveness, and operation security. The layout transmission channel key consideration marine project implementation. This paper investigates technical characteristics, application status, viable advantages conventional AC...
In recent years, the small-signal stability of modular multilevel converter (MMC)-based high-voltage direct current (HVDC) systems has garnered significant attention.
