“…Typically, STATCOMs have been used to provide reactive power at a PCC in a transmission network or distribution network for different purposes, e.g., control of voltage, load compensation and addressing LVRT; the most relevant feature is its capability of injecting a controllable reactive current independent of the grid voltage [17,[36][37][38][39]. A STATCOM is formed by a DC/AC converter, a capacitor on the DC side and a reactor on the AC side for filtering the high frequency components related to Insulated Gate Bipolar Transistor (IGBT) commutation.…”

“…The resulting approach, called STATCOM + ES (energy storage), is usually implemented to smooth the output power [18], electromechanical oscillation damping [42], power flow and, depending on the storage used, even frequency control or inertia emulation [17].…”

“…It is also desirable to use a STATCOM due to the possibility of working with decoupled control of the DC-link voltage and the reactive current [15]. However, one of the main drawbacks is the low energy density on the DC link capacitor installed in the STATCOM; this limits the reactive and active power capability of the STATCOM [16,17]. An improved version of the STATCOM is called the STATCOM + ES (energy storage).…”

Fixed-speed wind generator (FSWG) technology has an important presence in countries where wind energy started to be developed more than a decade ago. This type of technology cannot be directly adapted to the grid codes, for example those requirements related to the immunity level under voltage dips. That behavior is typically referred as low-voltage ride through (LVRT), and it usually implies certain reactive and active power injection requirements, both during a voltage dip and during the voltage recovery. In this context, a review is presented of the LVRT exigencies present in some of the countries with the most advanced grid codes (Denmark, Germany, Spain and the United Kingdom). In this paper, the capabilities of STATCOM-based devices for fulfilling the LVRT requirements in FSWGs are analyzed. For this purpose, two technologies are considered: a STATCOM with a supercapacitor, which improves its energy storage features; and a STATCOM with a supercapacitor and a DC-DC converter, to achieve higher discharge levels.

“…To ensure safe and stable operations, the Transmission System Operators (TSO) impose stringent connection requirements based on country specific grid structure. FACTS devices can pay a vital role in enhancing grid code compliance [6]. The FACTS devices can provide voltage and VAR support, when grid voltage sags due to network fault, creating imbalance between electrical and mechanical torque.…”

In this paper an innovative approach based on the use of Flexible AC Transmission Systems (FACTS) devices is investigated to explore the possibility of suppressing mechanical vibrations in wind turbines subjected to grid faults. The numerical analysis performed highlights the capability of FACTS devices to counteract the mechanical and structural vibrations in wind turbines due to the occurrence of electrical faults. In particular, we study the application of Unified Power Quality Conditioner (UPQC) as an effective means of suppressing the vibrations. In order to study the effectiveness of UPQC, first of all a detailed model describing the dynamic interaction between the mechanical and the electrical subsystems of a wind turbine is formulated and presented in this paper. The key feature of the developed model is that it can capture the impact of grid faults on the mechanical vibrations of drive train, flexible rotor blades and tower. Subsequently, the use of FACTS devices in general, with particular emphasis on UPQC in mitigating these vibrations has been investigated. Results show that FACTS devices are successful in mitigating vibrations due to electrical faults and they can be conveniently applied to stabilize the generator shaft speed, drive train oscillations, edgewise blade vibrations and tower responses. Further, superior performances of the UPQC as compared to STATCOM are also observed under conditions with increased fault duration.

The effect of numerical integration on time-domain power system simulations when evaluating the fault critical clearing time (CCT) is discussed in relation to stability and accuracy of integration methods. The specificity of CCT simulations is that the power system is close to its physical stability limits. While decreasing the time step is widely thought to be an effective measure to prevent numerical instability and ensure sufficient accuracy, it is shown that in real stability studies, numerical phenomena can be non-monotonic and cause misrepresentation of power system transient stability. For a given method, the effect depends on a combination of the loading of the generator whose CCT is evaluated and fault and network characteristics. The effect is illustrated with real-world simulation results. The paper makes recommendations on how the quality of CCT evaluation can be enhanced.Index Terms--Numerical simulation, numerical stability, power system analysis, power system faults, power system stability.
