Due to improved efficiency of solar photovoltaic (PV) systems, this article proposes a modified perturb and observe (MPO) maximum power point tracking (MPPT) algorithm. The MPO algorithm in question adopts approach that divides the power-voltage curve into four operational regions based on estimated open-circuit voltage. Additionally, enhances (MPP) method by reducing unnecessary step-size calculations, focusing only 10% section contains MPP. Consequently, two located far from MPP, below 90%...
Back-to-Back (B2B) HVDC systems can enhance cross-regional transmission capacity and overall power system stability. However, their use in interconnecting two extremely weak grids compromise This paper presents a comprehensive stability analysis of B2B to distinguish the root causes instability mechanisms identify critical short circuit ratio (CSCR) each converter station under inverter rectifier operations considering impact feedforward compensation dc-bus voltage controller. The study also...
The high-voltage voltage-source converter (VSC)- based multi-terminal dc (MTDC) grid is a key technology for integrating offshore wind energy and enabling bulk power transmission across nations continents. This paper addresses the small-signal stability of an MTDC equipped with flow controller (PFC) under extremely weak ac system interconnections. Using comprehensive linearized state-space model, eigenvalue analysis uncovers that, beyond welldocumented low-frequency oscillations (LFO), may...
DC circuit breakers are required to interrupt dc faults in multi-terminal HVDC (MTDC) grids. Consequently, their current limiting inductors can substantially impact the dynamic performance and stability of MTDC However, literature does not address assessment mitigation breaker inductance impacts on an grid equipped with a power flow controller (PFC). To fill this gap, paper evaluates effects PFC-equipped grid. Furthermore, expands capability PFC via development PFC-based damping improve...
To ensure the secure operation of a multiterminal high-voltage DC (MTDC) grid, power flow controllers (PFCs) are deployed to regulate current distribution among different transmission lines. Besides management, PFCs envisioned provide range functionalities such as stability enhancement, oscillation damping, and ancillary services host MTDC grid. This paper extends functionality PFC active damping grid oscillations caused by dc side resonance. Three simple effective compensators integrated...
