There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of this proposal is develop reliability assessment models when adding a wind farm (WF)/solar farm (SF), consisting of number of WTSs/SCGs, to a power system. These models involve finding WF/SF power output probability. Three different methods for computing the generated power probability distribution function (pdf) of a WF or a SF are proposed: (1) analytical method, (2) non-sequential Monte Carlo simulation, and (3) sequential Monte Carlo simulation. Historical wind speed/solar radiation data is utilized to perform the study. Further, force outage rates (FORs) of components are incorporated in the process of computing the WF/SF generated power pdf. All methods yield comparable results. The usefulness of the computed pdf is demonstrated by integrating them into a probabilistic production costing (PPC) model for assessing the reliability of a system comprising one or more WFs/SFs. Finally, a further development of these models includes a unit commitment economic dispatch model (UCED) to simulate real operation of power systems, specifically CG constraints in presence of VG at different penetration levels. Also, the UCED will be used to solve for optimal energy storage system (ESS) sizing and its expected charging and discharging power profile. This profile determines the expected ESS effect on reliability.
