“…It is proven in [6] that if the sequence of φn is selected to be passive the system with the sampled control law of (4) is asymptotically stable with zero Steady-State Error (SSE) with a quantifiable degree of robustness in the case of variations in the step response H (t). Passivity of sequence {φn} is guaranteed if {φn} is real symmetric positive semi-definite, such that Σ φn converges and (φn -2φn+1+φn+2) is also positive, semi-definite, for n0.…”

Abstract-Following the increase in development of large-scale renewable energy sources in the UK and the pressing need for adequate transmission capacity to accommodate the upcoming renewable generation, more state-of-the-art power flow control devices such as embedded High Voltage DC (HVDC) links will come into operation in the future GB transmission system to provide the additional capacity. However, an operational supervisory stability control system is required to ensure the coordinated control of power flow control devices in order to achieve optimal dynamic performance and make stability limits a less binding factor than thermal limits. The focus of this paper is to demonstrate the capability of the multi variable controller for coordinated control using a non-parametric sampled regulator control design method. This method is very attractive for applications in large power systems since the complexity of the controller design would not increase by size of the power system. Also, in this study, this design method has been demonstrated for two power system applications.Index Terms-Sampled Regulator, Stability Control and HVDC link.

“…But it cannot maintain the wind generator terminal voltage constant under randomly fluctuating wind speed [3]. Voltage or current source inverter based Flexible AC Transmission System (FACTS) devices such as Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), Dynamic Voltage Restorer (DVR), Solid State Transfer Switch (SSTS), and Unified Power Flow Controller (UPFC) have been used for flexible power flow control, secure loading and dumping of power system oscillations [4]. These FACTS devices are non-producing elements; moreover they increase the overall system costs of the fixed speed wind generator based wind farm.…”

To optimize the output power and reduce the frequency fluctuation in conventional fixed speed Induction Generator (IG) based wind farm, various controlling devices are used. But, this paper proposes that Permanent Magnet Synchronous Generator (PMSG) can work both as a power producing device and as a controlling device for IG. In this paper a more practical case has been considered where a wind farm is operated with a set of Synchronous Generators (SG). Thermal, Hydro and Nuclear Governors have been used for SGs. Wind farm has a capacity of 20% of the total SG's capacity. Both two-level and three-level converter-inverter based PMSG have been considered. Comparative results between IG and IG with PMSG are shown. Simulation results prove the effectiveness of the proposed system. Simulations have been carried out by using the laboratory standard power system software package, PSCAD/EMTDC.
