The rapid increase of wind power penetration into power systems around the world has led transmission system operators to enforce stringent grid codes requiring novel functionalities from renewable energy-based power generation. For this reason, there exists a need to asses whether wind turbines (WTs) will comply with such functionalities to ensure power system stability. This paper demonstrates that Type-2 WTs may induce sub-synchronous resonance (SSR) events when connected to a series-compensated transmission line, and with proper control, they may also suppress such events. The paper presents a complete dynamic model tailored to study, via eigenanalysis, SSR events in the presence of Type-2 WTs, and a systematic procedure to design a power system stabilizer using only local and measurable signals.

“…Some authors have already investigated the torsional dynamics of wind turbines (WTs) [14,15], and the potential contribution of WPPs to damp power oscillations [16,17]. However, these studies mainly focus on variablespeed WTs (i.e., Type-3 and Type-4).…”

“…The behavior of a network with wind generation can be studied supplying the farm equivalent wind as input to a conventional turbine model connected to the equivalent grid. The foundations of these models, their usual conventions and their limitations can be seen in (Akhmatov & Knudsen, 2002;Kazachkov & Stapleton, 2004;Fernandez et al, 2006 …”

Abstract. The connection of wind farm causes influence on the power system voltage stability because of the volatility and intermittency of wind power. In this paper, based on researching a regional wind farm, the influence of power fluctuation on power system voltage is analyzed. The influences of different settings of manual (mechanical) switched capacitor, SVC and STATCOM to the improving of power grid voltage are analyzed by PSCAD. Meanwhile, the improvement effects of the power grid voltages with different reactive power compensation devices are calculated by contrasting the curves of bus voltage volatilities during the increasing of wind power from 0 to 100% with different conditions.
