Multi‐stage coordinated dynamic VAR source placement for voltage stability enhancement of wind‐energy power system

Multi‐objective robust tuning of STATCOM controller parameters for stability enhancement of stochastic wind‐penetrated power systems

“…SVSMO3 model is used for STATCOMs and details of the model are explained in the following subsection. All the parameters of the dynamic models (except for the parameters to be optimised) are from [20, 32–34], which are recommended by WECC (Western Electricity Coordinating Council) and verified in many STATCOM‐based voltage stability studies [6, 35]. Specifically, if the recommended values for a certain parameter is a range instead of a fixed number, we will use the recommended value from [34].…”

Candidate bus selection for dynamic VAR planning towards voltage stability enhancement considering copula‐based correlation of wind and load uncertainties

“…Then, is calculated to evaluate the dynamic voltage performance of the system for each contingency with all capacity samples. Rotor angle constraint [29] is used to check the dynamic stability of the system. Samples failed to satisfy the constraint are penalized to make sure their are inferior to other stable cases.…”

Multi-stage coordinated robust var planning of wind penetrated power system based on voltage resilience indices

“…Therefore, reactive power deficiency may occur occasionally in a wind-penetrated power system [13]. Furthermore, there are also concerns about long-distance reactive power transmission [14] since the load center are usually far away from the installation sites of the wind farms. Apart from causing potential voltage stability problems [4], the reactive power deficiency may also contribute to the rotor angle stability [15].…”
