The power infrastructure is poised for dramatic change. Drivers include growth in non-schedulable distributed generation, improved economic, operational and energy efficiency, and higher grid resiliency under cyber-attacks and natural disasters. The utilities have adopted smart grid initiatives and Internet of Things methods to augment the available centralized command & HV side control with sensors (AMI, V/I), back-office data management & demand/system optimization to squeeze more performance out of the grid. However, it is becoming clear from field data that utilities today do not have the tools to manage the future grid with the precision needed. This presentation will show a new approach for distributed grid-edge control that allows the existing infrastructure to operate more efficiently in terms of energy, assets and economics, and enables new objectives such as high levels of PV hosting on distribution feeders, and the realization of grid-side demand management. Distributed control also offers a possible leap-frog opportunity for utilities in emerging markets to realize significantly higher performance at potentially lower cost. The presentation will present field data to validate the concepts being presented.
