Power systems have been in existence over 130 years and served the society well, along the way making it to be an essential service, often provided by multiple service providers.
Its technical form has been evolved over the years, mainly addressing the need to interconnect and stably operate large synchronous generating units which are often geographically dispersed and located away from the load centres. It is also supported by necessary and wellestablished planning practices, operational procedures, and governing rules. However, the norms and ethos of this well-developed system are now being challenged by the new technological developments.
Different forms of energy sources and energy uses are being created, moving us away from the familiar form of the power system that has served our societies well over a century. Nalin explains how well we can manage the transition, with minimum cost, robustness of the power supply, and the potential environmental impacts.
