“…In the symmetrical monopolar configuration, the transmission line (usually underground cable) is represented with two resistances r . This model can easily be extended to employ shunt conductance as in [14]. For the balanced AC transmission line, the impedance and admittance matrices are diagonal such that

Z ()(, normalj ω) = bold-italicZ ()(, normalj ω) (⟩⟨, 1, 1)

and

boldY ()(, normalj ω) = boldY ()(, normalj ω) (⟩⟨, 1, 1)

Initialisation of a hybrid AC/DC power system for harmonic stability analysis using a power flow formulation

2020

View full text Add to dashboard Cite

This study presents the initialisation of a hybrid alternating current/direct current (AC/DC) power system to determine the operation point around which the system is linearised as a starting point for an electromagnetic or harmonic stability analysis. To this end, each AC or DC power system component is modelled in the Fourier transform domain and further adjusted to a simplified representation compatible with a power flow formulation. The study also presents how voltage source converter (VSC) high‐voltage DC‐based systems can be analysed when the different VSC controls are applied. The result of the power flow solution is then used for the power converters’ initialisation.

“…For example, in [12], the hybrid AC/DC system description from [11] was incorporated into an OPF description for AC systems in the Julia programming language [13]. In addition, alternative formulations have been presented in the literature including shunt conductances within the HVDC grids [14].…”
