Impacts of Increased Intermittent Generation on Baseloaded Coal Operations

id=000000000001004412 The overall schematic for a coal-fired boiler and electric generation facility can be accessed at link 31. A reasonably good, but not overly technical, primer on how a coal-boiler steam generator facility works, as well as its key components, can be found at link 32. 31 www.irc.ee/6rp/valdkonnad/P6/energia/ Powerclean_state_of_the_art_final.pdf 32 www.sirgen.com/primer.html The NREL wind farm data sets contain simulations for wind farm outputs (link 33). Changes in recent ERCOT wind contracts, principally directed toward short-timed transmission needs, are reported in ERCOT’s Summary of Significant Wind-Plant Requirements (link 34). There are some small demonstration battery storage projects, such as in link 35, associated with wind farms at the 30% mandated renewables levels but these are not meaningful at the cycling coalboiler level. EPRI has developed a well thoughtout and comprehensive Cycling Operation of Fossil-Fueled Plants, Volume 6: Evaluation and Strategy, which can help serve as a useful guide and potential checklist (link 36). EPRI has some limited guidance on the installation of wearand–tear instrumentation and provides information on software suppliers in its Feasibility of Wear and Tear Sensors for Flexible Plant Operations (link 37). Link 38 reports the completion of a 1-MW battery wind storage project in Minnesota. 33 www.nrel.gov/wind/integrationdatasets/
