Smart Inverters to Support DERs and Grid Resiliency

Smart Inverters to Support DERs and Grid Resiliency

Their Operational Promise for Power Systems

April 28-29, 2021 | Online :: Central Time

Two key elements of facilitating the transition to a power delivery system with multi-directional flows, characterized by renewable energy and DERs, involve:

  1. Implementing advanced (smart) inverter technology that will appropriately “flex” with the legacy distribution and transmission systems to integrate with a new power delivery paradigm
  2. Conforming to updated interconnection standards — IEEE 1547, UL 1741 SA and others — that recognize how the system should accommodate this evolving generation and energy storage resources landscape

This course will examine the power system impacts triggered by the advancing penetration of solar and distributed energy resources, and what role smart inverters can play in supporting stable grid conditions.  It will identify how utilities, bulk power system operators, service providers and project developers must conform their practices to address the technology challenges triggered by these behind-the-meter and customer-originating power conditions. 

Learning Outcomes

  • Examine how solar and storage advanced inverters can improve grid performance under conditions of growing DER penetration
  • Discuss the ways in which smart inverters can provide power system operators real-time DER performance monitoring and improve grid stability
  • Examine how smart inverters can reduce the impact of high penetration DG on distribution feeders and boost their hosting capacity
  • Correlate the changes in codes and standards that will facilitate improved inverter functionality on power systems
  • Identify distribution storage opportunities utilizing batteries, their options and the path forward
