Operational Dispatch Strategy for Multi-energy Microgrid Considering Pulsed Load Characteristics

With the rapid development of information technology, the proportion of pulsed loads in microgrids has been steadily increasing. The repeated load-shedding and pick-up effects generated during pulsed load operation pose severe challenges to the dispatch of islanded systems. To address this, the paper accounts for the uncertainties in renewable power output and load demand by employing the Latin Hypercube Sampling (LHS) scenario generation method and the k-medoids reduction technique. Furthermore,a power-impact load model is developed based on equipment operational characteristics, and a multi-energy microgrid dispatch model is constructed with the objective of minimizing operational costs. Case studies on a microgrid demonstrate the dispatch results under typical scenarios with multiple uncertainties, validating the effectiveness of the proposed model.
