Power system dynamic modelling and analysis in evolving networks

By: Babak Badrzadeh, Zia Emin, Marta Val Escudero, Genevieve Lietz, Julia Matevosyan, David Jacobson, Nilesh Modi and Deepak Ramasubramanian

This workshop first provides a summary of all chapters of the Green Book on Power System Dynamics Modelling and Analysis in Evolving Networks and then focuses on detailed presentation of selected topics as follows:

• Part I introduces the importance of, and the need for, revisiting classical power system stability analysis concepts and textbooks. 
• Part II discusses different classes and sub-classes of power system stability, with a focus on considerations when performing power system dynamic analysis under high inverter-based resource (IBR) penetration scenarios. Practical experiences of various forms of power system instability are also presented.
• Part III provides an in-depth discussion of various dynamic modelling approaches including phasor-domain and electromagnetic transient programs and types of power system dynamic simulation software programs ranging from highly detailed to simplified screening. The use of screening methods and the applications of power system dynamic modelling and other tools for operational decision-making are presented in detail.
• Part IV focuses on different types of models and the necessary level of detail for each to ensure sufficient accuracy whilst respecting practical limitations. Power system components covered include generation technologies such as synchronous machines and IBR, HVDC systems, loads and distributed energy resources (DER) and wide-area network modelling including protection systems.
• The focus of Part V is to present dynamic studies typically conducted in power systems with a high penetration of power electronic interfaced devices. Grid interconnection studies for IBRs, HVDC systems, and FACTS controllers, and power system dynamic studies for operational and planning applications are presented. These include assessing and mitigating contemporary electromechanical oscillations and emerging electrical oscillations and control interactions. The impact of protective functions on power system dynamic performance, and studies of industrial power systems and microgrids are also presented.
• Part VI focuses on ensuring high-quality, accurate and up-to-date dynamic models for power system plants and the overall system. This spans model acceptance testing during early stages of plant development, to model validation where a mature design has been accomplished, and the plant is already connected and commissioned.
• Recognising the need to analyse a higher volume of data with higher accuracy and speed for increasingly complex equipment and power system responses, Part VII discusses contemporary enablers for power system dynamic analysis. It first discusses artificial intelligence (AI) and machine learning-based methods and cloud-based computing and then introduces the use of probabilistic analysis and optimisation techniques and elaborates on the importance of interoperability and standardisation.
