The many new distributed energy resources being installed at the distribution system level require increased visibility into system operations that will be enabled by distribution system state estimation (DSSE) and situational awareness applications. Reliable and accurate DSSE requires both robust methods for managing the big data provided by smart meters and quality distribution system models. This paper presents intelligent methods for detecting and dealing with missing or inaccurate smart meter data, as well as the ways to process the data for different applications. It also presents an efficient and flexible parameter estimation method based on the voltage drop equation and regression analysis to enhance distribution system model accuracy. Finally, it presents a 3-D graphical user interface for advanced visualization of the system state and events. We demonstrate this paper for a university distribution network with the state-of-the-art real-time and historical smart meter data infrastructure.
Abstract. Most storytelling systems to date rely on manually coded knowledge, the cost of which usually restricts such systems to operate within a few domains where knowledge has been engineered. Open Story Generation systems are capable of learning knowledge necessary for telling stories in a given domain. In this paper, we describe a technique that generates and communicates stories in language with diverse styles and sentiments based on automatically learned narrative knowledge. Diversity in storytelling style may facilitate different communicative goals and focalization in narratives. Our approach learns from large-scale data sets such as the Google N-Gram Corpus and Project Gutenberg books in addition to crowdsourced stories to instill storytelling agents with linguistic and social behavioral knowledge. A user study shows our algorithm strongly agrees with human judgment on the interestingness, conciseness, and sentiments of the generated stories and outperforms existing algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
