TRANSMISSION OPERATIONS & PLANNING

Operations Scheduling

Advancing the design and management of real time variability, uncertainty and frequency stability of bulk electric systems. 

SOLAR FORECAST Load Forecasting Initiative DCFlex

Research and Development Challenges

EPRI’s Bulk System Integration of Renewables and DER research area provides renewables/DER integration analytics and information; and develops tools, methods and models to support system operations, frequency control and balancing. These new approaches allow members to reliably and economically integrate onshore and offshore wind, distributed and central station solar PV generation, energy storage, and other emerging resources into the bulk system. It also provides members information and insights about the latest practices across the world.

System Operations Methods, Tools, and Analytics

Renewables and DER increase variability and uncertainty and may reduce inertia, but at the same time can provide bulk system services. This project set focuses on delivering new and improved methods to help operators integrate these resources while also maintaining reliability and managing costs. New methods to determine operating reserve requirements, assess and integrate renewable forecasts and monitor and understand inertia and frequency response are delivered to project members.
