#$%^&*AU2019101500A420200123.pdf#####ABSTRACT An economic dispatch algorithm is presented for smart microgrids with distributed generators over unbalanced directed networks. The increased complexity of modem energy network raises the necessity of flexible and reliable methods for power system operation. The algorithm mainly comprises four parts including variable initialization; selecting stepsize; dynamic tracking of Perron vector; updating variables. This invention proposes a fully distributed algorithm to address the economic dispatch problem (EDP) over directed networks and takes into account communication delays and noisy gradient observations. The present invention has broad application in economic dispatch in smart microgrids.1/6 Drawing :Start |Each generator initializes local variables Select uncoordinated stepsizes according to uncoordinated term a,(k) |Each generator sets k = 0 and maximum number of iterations kJ Each generator sends dual and surplus variables to its out-neighbors Each generator updates its surplus variable Each generator computes dual variable Each generator updates its output according to the new dual variable Each iteration sets k = k+1 k N y End Fig. 1
