Abstract

In view of the energy storage control problems of smart grid with multi-type service demands

an analytical model and strategy optimization framework based on semi-Markov control processes are developed by capturing the characteristics of stochastic distributions of service demands

behaviors of users and charging/discharging of energy storage devices. On this basis

with the minimization of long-run average cost of the operation in smart grids as the objective

and by combining with the performance potentials estimate on sample paths

a simulation based policy iteration optimization algorithm is presented. This algorithm alleviates the curse of dimensions induced by the large system state space

and is able to find a near-optimal policy with rapid convergence rate. Simulation results demonstrate the effectiveness of the presented method. This work is supported by National Natural Science Foundation of China (No. 61374158
