The impact of increased penetration of renewable generation has been the subject of much discussion related to system operations. As the percentage of generation from renewable generation provides us a greener and more sustainable future, it also introduces new challenges in scheduling and dispatching controllable resources to follow the net load and control the power balance in the system. The increased renewable generation tends to introduce more variability that must be met by the traditionally more flexible generation resources. Incentives are needed to encourage the existing generators of all types to maximize the availability of their operational “load following” flexibility and to encourage entry of new flexible suppliers such as energy storage devices or demand response.
