This presentation explains the importance of short-circuit current analysis in ensuring safe and reliable power system operation. It covers analysis methods, contributions from different types of embedded generators, and where to evaluate these contributions to prevent equipment damage, minimise outages, and protect personnel.

“This presentation outlines the network studies required for assessing small-scale embedded generation (SSEG) integration. It covers responsibilities, network modelling, and evaluations such as feeder hosting capacity, load flow, voltage studies, losses, protection coordination, power factor, rapid voltage changes (RVC), short-circuit current, and power quality—ensuring accurate planning through robust simulation models

This presentation covers the purpose and process of load flow studies for embedded generation projects. It explains how these studies assess voltage variation at the point of connection, network loading, and the impact of varying demand and generation across different times and seasons, using real-world example results.

This presentation examines technical losses in electrical networks, why loss analysis is essential, and how it is modelled. It explores variable and fixed losses, typical results, and strategies to minimise losses—improving network efficiency, lowering tariffs, and reducing carbon footprint.

This presentation details the criteria used to evaluate grid impact studies for embedded generation projects. It outlines assessment standards from both the consumer and producer perspectives, covering required studies, certification processes, and key compliance benchmarks.

This presentation explains the processes and responsibilities involved in data exchange for embedded generation projects. It covers the necessary studies, the flow of information between stakeholders, and how to calculate the data required for effective grid integration and compliance.

This presentation outlines the key studies and compliance requirements for Embedded Generator (EG) grid integration, as guided by the Grid Impact Study Guideline (Version 1.0, October 2022). It covers certification, frequency and voltage assessments, synchronisation, protection, and power quality. All outcomes are evaluated against NRS 048, NRS 097, and relevant sections of the South African

This presentation explores the shift from traditional electricity consumers to ‘prosumers’—users who both produce and consume energy. It covers key aspects such as load profiles, common embedded generation (EG) options, prosumer profiles, and behaviour patterns. With relaxed licensing for EGs up to 100 MW and declining PV and battery costs, municipalities are experiencing a surge
