报告摘要：We consider several distributed cooperative algorithms motivated by energy management, such as state estimation for smart grids and economic dispatch for Energy Internet. We analyze convergence of distributed parameter estimation algorithms with random observation matrices and communication graphs by a network of multiple nodes via information exchange. We establish the stochastic spatial-temporal persistence of excitation condition for mean square and almost sure convergence. We propose a distributed economic dispatch algorithm for the grid-connected microgrid, where each intelligent control unit iterates the estimated electricity price of the distribution system and the estimation for the average power mismatch of the whole microgrid by leader-following and average-consensus algorithms, respectively. The energy router iterates the incremental power exchanged with the distribution system. We prove that if the communication topology of the Energy Internet contains a spanning tree with the energy router as the root and there is a path from each intelligent control unit to the ER, then the estimated electricity price of the distribution system converges to its real value and the energy router achieves optimal asymptotically.
