The document discusses grid innovation and solutions for managing the evolving energy landscape. It notes that the grid of the future will have more renewable energy sources, smarter demand management, increased energy efficiency, and local generation. The document outlines TransGrid's iDemand program for monitoring solar generation, batteries, and consumption in real-time. It also discusses potential solutions like new transmission lines, phase shifting transformers, and batteries to address issues like outages and overloads on the grid. The goal is to share research and solutions to better understand challenges and enable a sustainable energy future through collaboration.

Phase shifting transformer solution
Phase angle regulator solution, reduces flow on 969 and restores loading on
969 to acceptable level, reduction in reactive line losses restores acceptable
volts at Gunnedah.

Phase shifting transformer
changes network impedance
and forces more energy to be
supplied from Armidale
