Abstract: The expansion of variable generation has driven a transition toward a 100% non-fossil (opens in a new window)power system. New system needs are challenging (opens in a new window)system stability and suggesting the need for a redesign of the (opens in a new window)ancillary service (AS) markets. This paper presents a comprehensive and broad review for industrial practitioners and academic researchers regarding the challenges and potential solutions to accommodate high shares of (opens in a new window)variable renewable energy (VRE) generation levels. We detail the main drivers enabling the energy transition and facilitating the provision of ASs. A (opens in a new window)systematic review of the United States and European AS markets is conducted. We clearly organize the main ASs in a standard taxonomy, identifying current practices and initiatives to support the increasing VRE share. Furthermore, we envision the future of modern AS markets, proposing potential solutions for some remaining fundamental technical and market design challenges.
