Modeling & Scaling Track: Grid Integration and Maintenance

On the opposite end of the spectrum from community power is integration of grid resources on increasingly large scales. This session discusses the increasing interest in how to both integrate and maintain a grids operatively across many different commercial and political entities. This becomes an even greater issue as the diversity of renewable resources and storage moieties become physically integrated with the grid. Ultimate grids will need to include the evolution of these resources as well as of the grid itself.

  • Ben Glenzer
    Solar Solutions For All

    Working as a Renewable Energy Professional since 1987 for multiple global corporations and global organizations. Those range from non-profit to Fortune 500 entities. By education an information technology systems engineer, I have worked in multiple leadership roles: program-/project- manager, senior consultant, vice president, partner, COO.
    Presentation Title: Energy Storage – The Game Changer in the Future Energy Market

    Presentation Description: With the latest energy storage technologies and its breakthrough capabilities utilities, grid-operators and communities will be capable to redesign the energy landscape in ways, which were not possible since Edison.

  • James Hyungkwan Kim
    Lawrence Berkeley National Laboratory

    James Hyungkwan Kim is an Energy Policy Project Scientist in the Electricity Markets and Policy Department at Lawrence Berkeley National Laboratory. I lead, support, conduct, report, and present research on renewable energy markets, policies, economics. Also, I conduct research on the value and costs of power system technologies and related market policy and develop methods to estimate dispatch of flexible resources in response to grid needs.
    Presentation Title: Enhancing the Value of Solar Energy as Solar and Storage Penetrations Increase

    Presentation Description: In this study, we offer a comprehensive analysis of the cost and value of multiple PV configurations across various solar penetrations associated with historical and projected U.S. wholesale power prices. We compare existing PV plants with grid-friendly PV options ranging from simple tilt and azimuth adjustments to vertical bifacial modules, provision of ancillary services, and addition of energy storage. We calculate marginal grid value using wholesale market prices reflecting energy, capacity, and ancillary services and coincident solar output profiles.

  • John Hammet
    WECS Renewables

    Began in Renewables supplying parts for Wind manufacturing and Interconnection construction in 1982, now fully involved with Commercial and utility solar and storage since 2010.
    Presentation Title: Utility electrical interface O&M planning

    Presentation Description: A $5 part can cause the revenue of a plant to halt for weeks. Nationwide WECS Renewables is responding to 5,000 -plus renewable substations needs across North America

    Presentation Title: Land requirements for utility-scale PV: An empirical update on power density (MW/acre) and energy density (MWh/acre)

    Presentation Description: The urgency of this topic stems from the need for up-to-date and accurate information on utility-scale solar’s power and energy density. The last major study of this topic was published in 2013, and—as noted in the abstract—was fraught with a variety of shortcomings. With increasing expectations for ever-higher penetrations of utility-scale solar in the United States, analysts, planners, and policymakers need an updated and better understanding of the land requirements—and potential land use impacts—to meet those expectations.

  • Yacob Hiben
    Yacob Hiben
    Mekelle University

    Born and raised in Ethiopia, as a young boy who lived in developing country his choices was
    limited when he finished high school. It had been always his dreams and ambitions to develop a career that has tangible impacts. As the objective of his career, he joined Mekelle University in 2002. Finally, he majored Mechanical Engineering and graduated with good grade in 2007 and joined Jimma University as a full time academic staff. This motivated him to pursue his joint master’s in Energy sponsored by KIC Innoenergy, 2011 cohort. Currently, he is a lecturer and Ph.D candidate at Mekelle University, Ethiopia.

    Presentation Title: Infinite NTU Modeling of Rock Bed Thermal Energy Storage
    Presentation Description: Packed beds incorporating rock as the storage medium and air as the heat transfer fluid have been proposed as a cost effective approach for thermal storage in solar power plants. In order to assess the viability of rock bed thermal energy storage (TES), it is essentially necessary to predict the air and rock temperature profiles through the bed during charging and discharging. Typically, the more detailed a model, the greater the computational effort required to solve it. For long-term analysis, a time-efficient model is necessary to prevent excessively long computation times. This paper evaluates the appropriateness of employing the less realistic but less costly Infinite NTU model.
