1. Electric Power Distribution: Matching Sources and Loads
Ward Jewell, Jerry Heydt
need markets participation
Continues work of PSERC T-21,
Evaluation of Distributed Electric Energy Storage and Generation
The infinite bus is finite
G&T systems have changed
Loads have changed

2. Long term goals better characterize distribution’s G&T source
better characterize distribution’s loads
reliability and quality
enumerate services distribution provides in matching source to load,
identify technologies to provide services
existing, emerging, and future
identify distribution opportunities to provide ancillary and other transmission services
optimize match between sources and loads
technically and economically

3. Project goals Enumerate distribution services
Evaluate feasibility of providing ancillary or other transmission
Develop specifications for each
(e.g. capacity, ramp rates, charge/discharge times)
Identify existing, emerging and future distribution technologies
with special focus on energy storage
distribution and transmission services each provides
Demonstrate the feasibility on industry team sites
Monitor transmission bus to characterize the source
Characterize distribution loads
Identify services needed by transmission and loads
Evaluate technologies to optimally providing the services
