Flexibility Requirement When Tracking Renewable Power Fluctuation With Peer-to-Peer Energy Sharing

Flexible load at the demand-side has been regarded as an effective measure to cope with volatile distributed renewable generations. To unlock flexibility, this paper proposes a peer-to-peer energy sharing mechanism that facilitates exchange among users while preserving privacy. We prove existence and partial uniqueness of market equilibrium provide centralized optimization compute equilibrium. The is further linearized by convex combination approach, turning into multi-parametric linear program (MP-LP) power output deviations being parameters. flexibility requirement individual calculated based on MP-LP. be specific, adaptive vertex generation algorithm proposed construct piecewise estimator optimal total cost subject given error tolerance. Critical regions strategies are retrieved from obtained approximate function evaluate requirement. does not rely exact characterization basis invariant sets thus influenced model degeneracy, common difficulty faced existing approaches. Case studies validate theoretical results show method scalable.
