Abstract This paper presents a microgrid power optimal dispatch scheme by using Markov decision process (MDP). To decrease the exchange power of PCC and smooth the fluctuations in different time scales, the reward function of MDP is established as entropy. During the decision process the optimal policy and optimal entropy value are solved through policy iteration. In the policy iteration, a specific policy set of wavelet packet-probability fuzzy has been proposed. It is used as the mapping from the state set of state of charge (SOC) of energy storage to action set of charge/discharge power of hybrid energy storage. The performance of this optimal method is discussed by study cases in the end.
