AbstractOffshore wind plant such as variable speed wind turbines (DFIG) will play an increasingly important role in future decades if ever-stringent requirements of energy security and low carbon emissions are to be met. Although some analysis of the impact of DFIG on system stability has previously been reported, none of it is based on a large network representing a real system, or the large network is simply not publicly available. This paper describes one such suitable equivalent dynamic network for stability studies based on the whole UK transmission system. The methodology for appropriate control system design and adjustment of the parameters under different dispatch conditions is presented. The network model is subsequently updated according to various National Grid future energy scenarios where DFIG models are appropriately added and distributed. Two important aspects contributing to future system stability are studied in detail, namely maximum value of the rate of change of frequency and transient stability. A number of detailed cases studies under varying wind penetration levels are presented which quantify the impact of key influencing factors such as the size of the largest generating unit for n-1 contingency, amount of primary system response, frequency dependency of load, and others. The study concludes that none of the individual factors can provide a complete solution and that careful cost benefit analysis is needed to determine the proper mix of services and reinforcements needed in the future.

Modeling and Simulation of the Anticipated Effects of the Synchronous Condenser on an Electric-Power Network with Participating Wind Plants

“…These variable-speed wind plants are decoupled from the corresponding electricity grid by power electronic converters. Different from synchronous generators, some types of wind plants are not able to play a part in frequency control activities such as inertia and governor response after a disturbance [33][34][35][36][37]. Although several control methodologies have been developed to allow Type-3 and Type-4 wind plants to be used for frequency regulation [38,39], such solutions are still not mandatory and normally do not operate for the Type-3 wind plant.…”

Review of DFIG wind turbine impact on power system dynamic performances

“…This also implies that the time interval for the spinning reserve to compensate the power imbalance shortens. This influence is manifest in small power systems, isolated microgrid/weak grids , and isolated island grids such as in Ireland and the UK .…”

Rate of Change of Frequency Estimation for Power Systems Using Interpolated DFT and Kalman Filter

“…RoCoF as high as ±1 Hz/s for durations of more than 1 s have been reported by grid operators of relatively smaller grids with high penetration of wind energy, such as those of United Kingdom and Ireland [1], [2]. Grid stability challenges associated with such a high RoCoF have also been reported and studied [3]- [5].…”
