Offshore substations are important sustainable power infrastructures subjected to strong vibrations induced by complex environmental excitations such as wind, waves, and currents. To protect the structures expensive facilities, lightweight vibration control devices highly desirable in offshore substations. With a high-performance energy dissipation device, inerter, conventional Tuned Mass Damper (TMD) is upgraded for control. The optimal parametric design performance evaluation of single-...
In this article, the decentralized adaptive secure control problem for cyber–physical systems (CPSs) against deception attacks is investigated. The CPSs are formed as a type of nonlinear interconnected strict-feedback with uncertain time-varying parameters. attack affects information transmission between sensor and actuator in multiplicative manner. A novel backstepping strategy established by exploiting particular kind Nussbaum functions flat-zone Lyapunov function analysis approach. It...
With the development of power systems, flow problem transmission line is becoming more and prominent. This paper presents a regulation method based on phase shifting transformer (PST). Firstly, working principle performance PST are analyzed. Then, simulation model BPA multi node system established. access reduces imbalance to less than 8%. On this basis, considering influence saturation effect leakage reactance, suitable for 220 kV grid designed. Three different conditions simulated by PSCAD...
In power systems with a high proportion of converter-based sources, Voltage Source Converter based High Direct Current (VSC-HVDC) links are required to take responsibility for providing frequency and voltage references. This paper proposes grid-forming control strategy VSC-HVDC in sources. The no longer relies on the output phase traditional PLL as reference system but instead uses Pf droop controller automatically generate system. QU is used achieve voltage-reactive characteristic VSC...
The numerous switching devices and extensive simulation scale of modular multilevel converter with embedded super capacitor energy storage system (MMC-SCES) pose a great challenge to the efficiency electromagnetic transient simulation. To address this issue, an efficient MMC-SCES electro-magnetic method based on Thevenin equivalent circuit is proposed in paper. employs nested fast simultaneous solutions approach model MMC-SCES, which not only significantly reduces time maintains accuracy,...
Abstract The transformer vibration and noise under the action of voltage current is a serious problem to equipment itself environment. In this paper, newly designed manufactured flexible DC considered. To reduce through proper installation on foundation, characteristics oil tank with different foundation designs are analysed. numerical simulation model two kinds established based FEA. convergence verified coarse fine meshes. characteristics, including natural frequencies, modal shapes,...
As more and renewable power is integrated into the grid through HVDC systems, situation where multiple links supply to an extremely weak AC system has become a common sight in future grids. This paper first introduced power-synchronization control method current vector for modular multilevel converter (MMC). Based on different of MMC, two strategies multi-MMC-HVDC are proposed, including peer-to-peer strategy master-slave strategy. For strategy, all MMC-HVDC converters use method. And master...
A comprehensive comparative analysis of different energy supply schemes is carried out to solve the coordinated problem in regional multi-energy complementary systems. Firstly, two distributed schemes, respectively gas turbine CCHP system and environment-source heat pump system, are proposed, corresponding operation strategies formulated; next, safety environmental performances municipal centralized scheme above analyzed; then, a probabilistic life-cycle cost model established, calculation...
