A synchronous backtrack algorithm, a welD-known method for distributed scheduling problems, has difficulties handling （A） rapid schedule adjustments and （B） impartial assignment. Thus, this paper proposes two kinds of heuristics： （1） parallel assignment and （2） multiple priority strategies, and developed the distributed scheduling system which makes use of the heuristics. It consists of schedulers for each power station and mediation agents which have cloning and merging functions to support the implementation of the heuristics. Finally, the result of experiment shows an improvement when handling the rapid adjustment and the impartiality issues with reasonable computational overhead.展开更多

In this paper, a new power coordination method of MAS is presented for MG. New way for dispatching controllable generations (CGs) and direct cooperation between storages and CGs are designed. Real-time emulations of the coordination, including the usage of both CGs and storages, have been carried out in islanded situation basing on this method, and much higher performance than conventional method is found.展开更多
