Considering the influence of transmission delay

noises and dynamically switching topologies in actual communication networks

an robust collaborative consensus algorithm for economic dispatch of non-ideal communication environment is presented. By introducing a virtual consensus variable

communications among smart units become more flexible as to enhance plug and play adaptability and consensus collaboration under dynamically switching topologies. With the assistance of a consensus gain function

the weakness of consensus-based algorithm to delays and noises in communication networks is eliminated. Finally

simulation results obtained from IEEE 39-bus and 118-bus test networks show that the proposed algorithm is suitable for the consensus economic dispatch of non-ideal communication network and satisfied optimization results can be obtained while the astringency is ensured.
