Toward an Intermediate Structural Representation of Organization in Complex Systems

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Organization is widely recognized as a fundamental concept in complex systems science, yet it rarely appears as an explicit object of scientific representation. Existing approaches successfully represent components, interactions, mechanisms, dynamical states, networks, or functions, but organizational properties are generally inferred from ...

Energy Flows Balance of Electric‐Heating Interconnected Microgrids Under Grid‐Forming Converter Integration Based on Heterogeneous Graph Convolutional Network

Energy Internet, EarlyView.
ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...
