A distributed stochastic gradient algorithm for economic dispatch over directed network with communication delays

•We propose a distributed primal-dual algorithm to solve constrained optimization problems over directed network.•The proposed algorithm adopts stochastic gradient descent method to update values of nodes for dealing with noise.•Theoretical analysis indicates that the algorithm can exactly seek the...
