Abstract:Based on consensus algorithms,a distributed multi-objective economic dispatch algorithm on environmental protection and economy is proposed for a micro-grid.Through estimating the global power mismatch by local power mismatch based on multi-robot task systems,this method doesn’t resort to the leader-follower consensus algorithm any more,which can avoid the occurrence of the difficulties in getting the global information for consensus algorithm.According to multi-robot task systems,each node on the communication graph saves the most up-to-date information from the other nodes.Moreover,it is shown that the proposed method can adapt to the varying load demand of the micro-grids and achieve a variety of multi-objective economic dispatch situations in the micro-grid.Simulation case verifies the validity of our results.
