DERs interconnected with the grid position a utility to better manage peak demand, avoid transmission overloads and keep electricity flowing, but interconnection of battery, solar and other DERs is not without its challenges. Jason Allnutt from IEEE Standards Association discusses a standard that has become an “essential resource” for stakeholders.

A newly released standard creates nationally applicable guidance for DER manufacturers on how grid support functions in their products will be tested. Brian Lydic, chief regulatory engineer at the Interstate Renewable Energy Council (IREC), talks about what this means for enabling the grid modernisation that will be needed to support high levels of renewable energy and energy storage.

Battery system integrators must navigate a broad array of technologies and varying market drivers when putting systems together. Andy Colthorpe speaks to Powin Energy and Sungrow about the engineering challenges involved in building lithium-ion battery storage.

Powin Energy VP Danny Lu has said that attaining what is considered the highest standard in safety means that projects using the company’s Stack 225 battery storage system products can be executed faster and pack more capacity onto a single site.

An electric vehicle-to-grid (V2G) charging system, which allows for bi-directional flows of power from US maker Fermata Energy has become the first to receive certification under a new standard introduced by UL.
