Frequency response due to a large generator loss with the increasing penetration of wind/PV generation - A literature review

This paper provides an updated review of the literature on the power system frequency response due to a large generator loss with the increasing penetrations of wind and PV generations. At present, these wind/PV generators continue to increase their visibility as a source of cleaner electricity generation, and play a significant role in the electricity market׳s energy plans. Along with the increasing levels of wind/PV penetration in power system networks, there is an increasing concern over the network frequency response especially under the loss of a large synchronous generator. It is widely agreed upon that the frequency response has become more susceptible with the increase of wind/PV generation due to the lack of inertial support from these generators. This paper aims to review the recent literature into the system frequency response in the likelihood of the sudden loss of a large conventional generator with the increasing penetration of wind/PV generation. This literature review attests that existing primary control support schemes may not provide adequate frequency support for some networks with an increase of wind/PV generation. The prominent finding is that system operators do not have access to any specific tool that would allow them to determine the required frequency support on a real-time basis.
