“…Recently, renewable wind energy has been developed rapidly and it becomes the third electricity source of China. However, a lot of large-scale wind farms integrate to power grid brings great influence on voltage stability of main network [1,2]. To reduce this negative influence, the grid codes always require that wind farm provides the capability of dynamic voltage control by continuously adjusting reactive power supplied to the power system.…”

Uncertainties of renewable energy sources like wind power are one of the considerable challenges of prosumer microgrids. To meet the grid codes requirements regarding the voltage stability of wind farm integration, finding the balance between providing the demanding dynamic performance of the voltage and reactive power, and at the same time decreasing the investment on centralized reactive power compensation device, becomes an important research topic. This paper compares the effects of the static synchronous compensator (STATCOM) and static VAR compensator (SVC) on transient voltage stability at the point of common coupling (PCC) of a doubly fed induction generator (DFIG)-based wind farm. And a new fast coordinated control scheme of STATCOM and DFIG is proposed for minimizing the capacity of centralized reactive power compensation device and making the best use of the reactive power control capability of DFIG. The simulation results based on test system show that STATCOM, even with less capacity, can contribute more reactive power than SVC for voltage stability, especially during the serious voltage drop transient stage, and perform a faster voltage recovery time after fault than SVC, proved to be a more economic choice; The proposed coordinated control scheme can not only improve the transient voltage stability, but also help reducing the capacity of STATCOM, so that the cost of investments in wind farms would be reduced.

“…Moreover, these renewables may significantly deteriorate the inter-area oscillation modes with oscillation frequency between 0.2 and 0.8 Hz [4,5]. To damp out the inter-area oscillations by DFIGs and SPVs, an additional damping controller to the converter control loop is required [6,7].…”

“…Previously, several works used DFIGs and SPVs equipped with damping controllers to enhance the oscillatory stability and stabilise the inter-area oscillations [6][7][8][9][10][11]. The effects of DFIG wind turbines on the inter-area oscillation modes are investigated by applying the damping ratio sensitivity [6].…”

Recently, renewable energy sources such as wind turbines and solar photovoltaics have been increasingly applied in power systems to support inflated load demands. These renewable sources may be placed at locations that provide higher controllability of inter-area oscillations than those of conventional synchronous generators. Thus, an improved damping effect from such renewables can be expected. On the other hand, the signal selection of the wide-area damping controller (WADC) is normally conducted at an operating point. The strength of the input-output pairs of the WADC will consequently change according to the system operations. This study presents a WADC of wind and solar power sources using probabilistic signal selection. After selecting the most suitable input-output pairs, the control parameters of WADC are optimised using a robust control strategy and multiple-pole placement at several operating points. The designed WADC is evaluated by small-signal and transient stability studies in the IEEE 50-machine 145-bus system to guarantee the stabilising effect of the proposed WADC of wind and solar compared to that of the conventional WADC of synchronous generators.

“…Particularly, the ability of wind power generation to damp power system swings is a momentous problem that should be verified by designers. To actively damp the power swings, wind power plants have been suggested to be equipped with power swing damping (PSD) controller . In a system with multiple damping controllers like power network stabilizer (PNS), PSD controller, and supplementary damping controller (SDC), variables of the PSD controller of wind power plants (WPP) should be optimally tuned in a concurrent manner.…”

Summary The contribution of hybrid controller of large‐scale wind power generation system (LWPGS) in system stability and profit is discussed throughout the paper. To this purpose, it is necessary to formulate the impact of high infiltration of wind turbines on the dynamic stability of power networks. A mathematical model of a multi‐machine power network is developed first, based on which an extended small‐signal stability analysis procedure is projected and discussed to handle the influence of LWPGS on oscillatory modes. This model is then applied for analyzing the damping impact of the LWPGS and ancillary service (AS) associated with its controller. After the model creation, the profit created by LWPGS hybrid controller as AS is analyzed by multi‐objective optimization based on low‐frequency oscillation stability criterion and generation cost. Two scenarios for the valuation of small‐signal stability as an AS provided by LWPGS controller are considered. The study is based on a changed 16‐machine 5‐area network. The comparative analysis of the results is also presented to elucidate the suggested approach. Copyright © 2015 John Wiley & Sons, Ltd.
