Abstract: Large scale integration of variable and uncertain Renewable Generation (RG) in power systems causes frequent load-generation imbalances. Systems require additional operational flexibility to ensure secure and reliable power system operations. Flexibility can be enhanced by increasing ramping availability from resources at generation and demand side. Flexible Ramp Products (FRPs) are implemented in mature power markets to ensure ramping availability from such sources. Accurate FRP design can effectively manage load-generation imbalances and ensure secure system operations. This has attracted quantum research attention in FRP related challenges. However, there is limited understanding of power system flexibility enhancement capability of FRPs, design components, modelling and implementation of FRPs in various electricity markets. A detailed study on this can support industry and academia to develop improved FRP designs. Also, this gives motivation to explore FRP availability from different sources. In this context, this paper provides a detailed review on FRPs, and problems and research challenges in existing FRP frameworks. Unique areas such as net load variability and uncertainty estimations in FRP modelling and FRP implementation in various power markets are extensively discussed. A case study is also conducted to demonstrate the advantages of implementing FRP. It concludes that FRP is a promising solution to manage frequent load-generation imbalances. However, there is a significant scope to improve existing FRP designs and their implementation. Also, FRP availability from different RG sources or RG mix needs to be adequately assessed to maximize the environmental advantages from them.
