The existing method cannot realise the optimal economical dispatch operation of cascaded‐type microgrids with capacity constraints in a communication‐free manner. To address this problem, a new optimal economical dispatch control scheme is proposed for the islanded cascaded‐type microgrids without communications. Compared to the existing method, there are two prominent advantages: (i) global optimal economical operation with capacity constraints is realised; (ii) improved load voltage quality is obtained. Then, the stability of the proposed scheme has been analysed with a small‐signal analysis method. Finally, the effectiveness of the method is verified by both simulations and experiments.
