Distributed energy resources (distributed generation, energy storage and controllable loads) will have significant impacts, both positive and negative, on distribution system operation. Negative impacts include voltage regulation difficulties, protection challenges and potential for significant impact on electric utility revenues. Positive opportunities include demand reduction, reduction of greenhouse gas emissions from central generating facilities, participation in ancillary services markets and reliability improvement during major outages through microgrid island operations. This panel will explore these opportunities and challenges with an emphasis on the role of Distribution Management System (DMS) in DER Management. Presentations include case studies from electric utilities, vendor views of the system requirements (DERMS) and system integration and status of key standards that are being developed to support this need (eg. IEEE PES 2030.7 : Distribution Resources Integration WG/Microgrid Controllers).
