The selection of suitable models and solutions is a fundamental requirement for conducting energy flow analysis in integrated energy systems (IES). However, this task is challenging due to the vast number of existing models and solutions, making it difficult to comprehensively compare scholars' studies with current work. In this paper, we aim to address this issue by presenting a comprehensive overview of mainstream IES models and clarifying their relationships, thereby providing guidance for scholars in selecting appropriate models. Additionally, we introduce several widely used solvers for solving algebraic and differential equations, along with their detailed implementations in the energy flow analysis of IES. Furthermore, we conduct extensive testing and demonstration of these models and methods in various cases to establish benchmarking datasets. To facilitate reproducibility, verification and comparisons, we provide open-source access to these datasets, including system data, analysis settings and implementations of the various solvers in the mainstream models. Scholars can utilise the provided datasets to reproduce the results, verify the findings and perform comparative analyses. Moreover, they have the flexibility to customise these settings according to their specific requirements.

This document is a summary of a report prepared by the IEEE PES Task Force (TF) on Microgrid (MG) Dynamic Modeling, IEEE Power and Energy Society, Tech. Rep. PES-TR106, 2023. In this paper, the major issues and challenges in microgrid modeling for stability analysis are discussed, and a review of state-of-the-art modeling approaches and trends is presented. In the context of the IEEE 1547 standard, the document covers issues associated with component models for MG dynamic studies and simulations, including generator and grid modeling, full and average converter models, unbalanced and balanced system conditions, dynamic and static loads, protection requirements, and detailed and simplified controls considering communications delays, packet losses, and security issues. Considering the future integration of grids and MGs to form broad integrated networks, a discussion is presented of the use of phasor vis-à-vis electromagnetic transient simulation tools for MG dynamic stability studies, as well as modeling scale-up issues and MG equivalent models. Specifically white-, grey-, and black-box models, are presented. This TF paper and companion report constitute a modeling guide for R&D groups working on developments and standards of MGs with a focus on stability issues.
