The grid is a marvel of ingenuity and a creation worthy of national pride, but the relentless impacts of climate change, aging infrastructure and a rapidly shifting generation profile have exposed its fragility. Today, electric systems are facing changes comparable to how fixed-line telephone systems transitioned to mobile.

Download this guide to understanding what is grid modernization today, its major drivers and key areas electricity providers need to focus on to chart a resilient path forward to effectively and efficiently modernize the grid.

Transmission entities take models at face value with no analysis of model quality. Unintentionally incorrect models (parametrization) were used and never questioned. Intentionally incorrect models are used to get through the interconnection process easily. There is a lack of technical expertise in companies to detail EMT models and analyze a vast number of models for interconnection requests. Interconnection studies not picking-up reliability issues with positive sequence studies mostly, will not identify transients problems.  Furthermore, detailed EMT studies without accurate models of protection and inappropriate use of EMT models, or overestimation of model quality, will bring wrong results.

Interesting eBook. I wonder how much legacy systems are going to be a challenge in grid modernisation.  That is, legacy software that does the job and is kept going because the users are familiar with it, despite it might have security vulnerabilities. 

There is also the issue of "legacy equipment": old kit that is still functioning but the plans have been lost and things like buried cables that no-one knows where they are actually in the ground. 

Upgrading these systems to the new era could be costly and difficult, perhaps?
