摘要：Truck-mounted mobile emergency resources (MERs) play a significant role in microgrid formation and regulation for power system resilience enhancement. This paper proposes a distributed fixed-time secondary control (DFSC) scheme to regulate the frequency and active power sharing in islanded microgrids with MERs. The proposed DFSC scheme is designed based on a general directed communication graph which considers MER characteristics (e.g., mobility, flexibility, and potential cyber threats). Each DER receives data from its neighbors through directional communication links. The proposed pinning control strategy selects only a small number of DERs for pinning, which have access to the reference frequency information and would guide the operation of remaining local DERs and MERs. In addition, the guaranteed convergence time is determined by control parameters and communication graph without applying the initial operation states. The paper demonstrates that the desired control performances (i.e., frequency restoration and accurate active power sharing) are realized in a timely fashion considering frequent operations of MERs. Case studies are tested and discussed for load variations, different control parameters, communication link failures, and MER operations through time-domain simulations in PSCAD/EMTDC platform.
