Abstract

This article details the design and real-world implementation of a mission-critical microgrid for an aerospace rocket launch center. The project focuses on ensuring energy security and reliability during launch operations, while also prioritizing emission reductions during non-operational periods. This paper makes significant contributions by identifying and addressing key challenges in the seamless integration and implementation of critical functionalities within microgrids, ensuring their reliable operation across various scenarios such as island capability and black-start operation. Key challenges including the mitigation of transformer inrush currents, fault detection in an ungrounded system, and power balance during off-grid operation have been successfully solved. The microgrid has been operational since June 2023. Experimental results from the commissioning phase are also included, which confirm the design's effectiveness in ensuring energy security and significantly reducing CO₂ emissions.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
