Abstract
The fast growing penetration of intermittent renewable resources has outpaced the associated transmission development in light of the difficulty to manage congestion with only dispatchable resources under the Security Constrained Economic Dispatch (SCED) process. To this end, Dispatchable Intermittent Resource (DIR) is introduced to address market and operational issues relating to the manual curtailment of Intermittent Resources. This report investigates the influence of DIR on the economical and reliability benefits yielded by dispatchable operation. We implement a simulation tool to emulate the clearing of the hourly transmission-constrained day-ahead markets for power systems with DIR. We run the simulation over a year to capture the power system sources of uncertainty, including the generator availabilities, load demands and renewable power outputs. The approach uses a 1-hour snapshot representation to model the time-dependent renewable resources and load. We illustrate the capability and effectiveness of the simulation method on a modified IEEE 118-bus system.
