Facilitating DERs and Services Using Operating Envelopes - Insights from Real Implementations

The uptake of residential and commercial solar photovoltaic systems, batteries and electric vehicles continues to grow around the world. These technologies, known as Distributed Energy Resources (DERs), are also creating opportunities for their owners to provide services to the system operator through aggregators (now allowed across the US thanks to the FERC order 2222). However, as the volume of DERs providing services increases, it is important to ensure the integrity of the poles and wires that connect our houses and businesses. To achieve this, the use of Operating Envelopes, i.e., the use of time-varying export and import limits at the connection point of customers, is a concept being tested in countries such as the US and Australia. This panel will provide insights and discuss the challenges associated with the corresponding calculations, modeling aspects, and implementation of Operating Envelopes by distribution companies. Presentations in this panel session: - Operating envelopes under uncertainty with partial prosumer observability (23PESGM4367) - Model-Free Operating Envelopes (23PESGM0885)
