To cope with the growing penetration rate of renewable energy and to enhance absorption capacity wind power, this paper investigates applications an Integrated Energy System (IES), Hydrogen Compressed Natural Gas (HCNG), power-to-hydrogen (P2H) devices within IES. It employs power-to-gas gas blending hydrogen construct efficient electricity–gas–electricity flow loop, establishing a Gas–Electricity Coupling (NGECS) model. On basis, coordinated scheduling method for gas–electric coupling...
This paper proposes a RoCoF droop control, which relieves the transient frequency change process by controlling energy of DC side capacitor. Firstly, analyze and classify control time scale wind power system (WPS). Under electromagnetic scale, combine low-pass filter (LPF) differential link to obtain system. Therefore, is effectively improved. Secondly, on basis inertia analysis original synchronous generator, further derivation characteristics. Compared with traditional enables inverter...
This paper proposes a fast phase capture (FPC) scheme and applies it to the control strategy of grid-tied inverters under imbalanced voltage. Firstly, method for quickly extracting sequence components power signals is derived through symmetrical component method, real-time calculation proposed based on rotating reference frame, thus avoiding phase-locked loop (PLL) closed-loop adjustment process. Secondly, inverter suppresses negative current or fluctuations direct resonance controller, so...
Owing to the increased proportion of new energy power generation, such as wind and photovoltaics, connected island grid, system powered by voltage source converter-based HVDC (VSC-HVDC) is prone oscillate or even lose stability when disrupted. In this study, considering rapid compensation (RPC), an active control strategy has been suggested for receiving-end converter station VSC-HVDC that could efficiently suppress low-frequency oscillation system. First, mechanism inhibiting grid analyzed...
Abstract To alleviate the increasing distributed energy penetration problem in distribution network under “double carbon”, a P2P multi-microgrid power sharing and trading method based on alternating direction of multipliers (ADMM) are proposed hybrid multi-microgrid. The paper constructs optimization model each sub-microgrid for transactions ADMM algorithm. Finally, is simulated verified using composed three microgrids. results show that electric tariff between microgrids obtained from this...
To promote fault diagnosis accuracy and efficiency of high voltage circuit breaker, a novel approaches based on kernel principal component analysis (KPCA) probabilistic neural network (PNN) is proposed in this paper. Firstly, eight critical features are extracted from tripping/closing coil current curve. Then, KPCA applied to eliminate redundancy among features, small scale, more informative mutual orthogonal components extracted. Finally, crucial used establish inputs the PNN studied. The...
