Abstract: The dynamic economic dispatch problem with energy storage in a smart grid scenario is studied, which aims at minimising the aggregate generation costs over multiple periods on condition that the time-varying demand is met, while physical constraints on generation and storage as well as system spinning reserve requirement are satisfied.
Main text The demand for renewable energy is increasing, driven by dramatic cost reductions over the past decade. 1 However, increasing the share of renewable generation and decreasing the amount of inertia on the power grid (traditionally supplied by spinning generators) leads to a requirement for responsive energy storage
