The session reviews existing use cases via the EPRI repository, then details Step 4 for drafting use cases, including goals, narratives, actors, assumptions, contracts and preconditions, triggering events, and step-by-step scenarios. It then introduces UML, explaining unified modeling language concepts and core diagram types such as class and use case diagrams, plus related behavioral and structural views.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/lecture-3-eh2750-power-systems-advanced-course-smartgrids-use-case-methodology-uml/655921/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/lecture-3-eh2750-power-systems-advanced-course-smartgrids-use-case-methodology-uml/655921.png","ImageObject",300,407,{"name":42,"@type":43},"How to eat","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-25",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",6,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the role of the IEC 62559 public specification in this lecture?","Question",{"text":63,"@type":64},"It is presented as a suggested way to work on developing requirements for new computer applications for power systems.
