Title: Report on Integration of Existing Grid Models for N-R HES Interaction Focused on Balancing Authorities for Sub-hour Penalties and Opportunities

Abstract

This report provides a summary of the effort in the Nuclear-Renewable Hybrid Energy System (N-R HES) project on the level 4 milestone to consider integration of existing grid models into the factors for optimization on shorter time intervals than the existing electric grid models with the Risk Analysis Virtual Environment (RAVEN) and Modelica [1] optimizations and economic analysis that are the focus of the project to date.

  • As the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program prepares to initiate a new cost-shared research and development (R&D) effort on photovoltaic (PV) manufacturing, it is useful to review the experience to date with consortia focused on PV R&D, manufacturing, and testing. Information was gathered for this report by conducting interviews and accessing Web sites of 14 U.S. consortia and four European consortia, each with either a primary focus on or an emerging interest in PV technology R&D, manufacturing, or testing. Additional input was collected from several workshops held by the DOE and National Academy of Sciences (NAS)more » in 2009, which examined the practical steps -- including public-private partnerships and policy support -- necessary to enhance the United States' capacity to competitively manufacture photovoltaics. This report categorizes the 18 consortia into three groups: university-led consortia, industry-led consortia, and manufacturing and testing facilities consortia. The first section summarizes the organizations within the different categories, with a particular focus on the key benefits and challenges for each grouping. The second section provides a more detailed overview of each consortium, including the origins, goals, organization, membership, funding sources, and key contacts. This survey is a useful resource for stakeholders interested in PV manufacturing R&D, but should not imply endorsement of any of these groups.« less
  • As renewable energy generating sources, such as wind turbines and solar power systems, reach high levels of penetration in parts of the United States, the National Renewable Energy Laboratory (NREL) is helping the utility industry to peer into the future. Using software modeling tools that the lab developed, NREL is examining the future operation of the electrical grid as renewable energy continues to grow.
  • The study described in this chapter demonstrates the benefits of BA consolidation with the help of a detailed WECC system model and advanced methodology, which is also described in this chapter. The study aims to determine the potential savings in production cost and reduction in balancing reserve requirements in the WECC system. The study has found that effective use of the diversity in load and variable generation over a wide area can indeed help to achieve significant savings. The implementation cost for the consolidation was beyond the scope of this study. The analysis was performed for two different scenarios ofmore » VG penetration: 11% (8% wind and 3% solar) and 33% (24% wind and 9% solar) of WECC projected energy demand in 2020. In analysis of balancing reserves, the objective was to determine the reduction in balancing reserve requirements due to BA consolidation, in terms of required capacity and ramp-rates. Hour-ahead and 10-minute ahead forecast errors for load, wind, and solar were simulated. In addition, 1-minute resolution load, wind and solar data were used to derive balancing reserve requirements i.e. load-following and regulation requirements for each individual BA and for the consolidated BA (CBA). The reduction in balancing reserves was determined by calculating the difference between total reserve requirements that need to be carried by different BAs if they operate individually, and reserve requirements that need to be carried by the CBA. The study results show that the consolidated WECC system would have about a 50% overall reduction in balancing reserves for the 11% penetration scenario and a 65% reduction for the 33% penetration scenario in comparison with total reserve requirements that need to be carried by different BAs if they operate individually.« less
  • The overall objective of this research program is to gain increased understanding of the energetics associated with chemical and physical interactions involving supercritical fluids. Emphasis has been placed on reactions involving CO/sub 2/, Freons, and hydrocarbons. Our approach to the accomplishment of this objective has been first, to measure heats of mixing (H/sup E/) for selected binary systems at temperatures and pressures in the vicinity of the critical points of one or both of the components. These experimental H/sup E/ data are incorporated into appropriate equations of state or modified equations of state in order to describe the variations inmore » H/sup E/ with temperature and pressure. This process allows us to gain insight into the origin of the energy changes which occur. Since the energy changes are large and occur over a few degrees in some cases, the ability to predict them is necessary in designing equipment for use in carrying out supercritical fluid processes. In addition, H/sup E/ data in critical regions provide an excellent test for the validity of the equations used to describe these data. Several systems which illustrate these principles are presented and discussed in this report. These systems are (propane + CF/sub 2/Cl/sub 2/), (CO/sub 2/ + pyridine), (CHF/sub 2/Cl + N,N-dimethylacetamide). (CHF/sub 2/Cl + 2,3 dimethylbutane), (CF/sub 2/Cl/sub 2/ + N,N-dimethylacetamide), and (CF/sub 2/Cl/sub 2/ + ethane). 26 refs., 5 figs., 2 tabs.« less
