Abstract: Current distribution systems cannot support simultaneous and identical actions of a large number of distributed flexible energy resources reacting to an identical signal. This talk presents a transactive energy market framework when their access to transactions is restricted. A nonlinear pricing structure incentivizes small transactions spread out among arrivals of operation opportunities. A self-exciting point process expresses operation permissions. The problem of optimal operations in this market to maximize the cumulated revenue is modeled as a piecewise deterministic Markov decision process. Various properties of the optimal value and sensitivity to market parameters are studied. This is a joint work with Boris Defourny (Lehigh University).
