WebIn this paper, we consider a probabilistic microgrid dispatch problem where the predictions of the load and the Renewable Energy Source (RES) generation are given in the form of … In the hierarchical hidden Markov model (HHMM), each state is considered to be a self-contained probabilistic model. More precisely, each state of the HHMM is itself an HHMM. This implies that the states of the HHMM emit sequences of observation symbols rather than single observation symbols as is the case for the standard HMM states. small toy blocks
