Title: “Infrastructure Transformation Toward a Reliable and Resilient Power Grid”
Abstract: The electric power industry is under transformative changes toward high efficient, service oriented, and sustainable future. Climate change has induced increasing risk to power grids with higher frequent natural hazards which are threats to power grid resilience. High penetration renewables and DERs, along with the rapid growth of natural gas generation, have not only aggressively changed the fuel mix in our grids, but also have brought in new challenges and opportunities in the system and market operation. For example, Inverter-based Resources (IBRs) could induce low inertia and low-fault current into the power system, larger scale natural gas generation would need extensive Gas-Electric coordination, etc. On the other side, the aging infrastructures in our power grids would need to be hardened and rebuilt to meet the transitional supply-demand patterns. Competitive Transmission Planning is a new battle ground in the US power system developments which aims for a more cost and technical effective infrastructure investment and operation model. At this presentation, we will have a holistic review on the above transitional trends in the industry, and discuss the call of technology innovation and researches to meet these challenges. The most recent published IEEE PES Technical Reports and the IEEE PES Industry Survey result will be referenced.
Bio: Dr. Jay Liu is a Senior Lead Engineer at PJM. He has near 30 years experiences in power industry working on infrastructure planning, implementation and operation. He has developed, coordinated and integrated more than 20GW conventional and renewable energy resources into the power grids.

Title: “DC Power Distribution in Buildings”
Abstract: This presentation explores the use of DC power distribution in buildings. DC microgrids have gained recent academic appeal for zero-net-energy (ZNE) and grid-interactive efficient buildings. Though DC has many advantages, researchers and developers have previously cited concerns about efficiency, cost, and a lack of products. This presentation details the efforts at LBNL to study the energy and cost savings in a DC building. The research involves precise electrical models of buildings and converters, and ultimately shows that DC has the potential for 12% savings in commercial ZNE buildings with storage.
Bio: Daniel Gerber is a Research Scientist at Lawrence Berkeley National Labs. He received his BS and PhD in electrical engineering from MIT (2010) and UC Berkeley (2017), respectively. Daniel’s PhD dissertation topic was on developing a fully on-chip LED driver with novel techniques such as multilevel converters, sigma-delta control, and active ripple cancellation. His postdoctoral work at LBNL focused on DC power distribution, and he was the technical lead on much of LBNL’s studies in the efficiency and economics of DC power. Daniel also developed several DC power analysis tools and built up the LBNL DC testing lab. His other interests span power electronics, power systems, microgrids, controls, and networked buildings.

Title: “Power System Frequency Control and Stability Analysis with Increasing Renewable Energy Penetration Level”
Abstract: With the ever-increasing penetration level of renewable energy generation units and the replacement of traditional synchronous generators, the issues associated with the deteriorated performance of power system frequency regulation and potential grid frequency instability become more significant. In this seminar, the inertial control algorithms are discussed and analyzed for a renewable energy generation unit. The concept and design of Virtual Synchronous Generator are comprehensively discussed in order to enhance small-signal stability and frequency stability of power systems with high renewable energy penetration level. By imitating the mathematical model of a synchronous generator, some undesirable features are inevitably introduced in Virtual Synchronous Generator control. The conflict between fast varying wind power input and slow dynamics of Virtual Synchronous Generator controlled inverter is further discussed. Virtual Synchronous Generator with multiple virtual rotating masses is proposed in order to improve the active power tracking performance as well as to boost inertial control of a wind power generator. The performance of proposed inertial control is verified in IEEE benchmark power system with wind power integration.

Title: “Inexpensive thermal storage at the smaller scale”
Abstract: The energy system is undergoing radical transformation. We are shifting away from dispatchable fossil resources to variable, if somewhat predictable renewable generation. The IoT is allowing unprecedented state estimation and controllability of devices. Batteries are becoming increasingly inexpensive. Yet, a substantial fraction of energy is still used to heat and cool buildings, often at the wrong times. Thermal storage could form an interesting sustainability alliance with battery storage to improve our ability to manage energy while providing energy services when they are needed. While thermal storage for large commercial buildings has been around for decades, at the small commercial and residential scale it has never crossed the technological valley of death, despite valiant attempts. In this talk, we will present a concept to overcome two of the main barriers to commercial success: cost and battery-like performance. This is done via a combination of geometry and materials. The heat transfer mechanisms that lead to the high performance of the system are discussed, followed by potential manufacturing and integration opportunities.

Presenter: Dr. Kevin Tomsovic, CURENT Center Director, University of Tennessee
Title: “Changing Testing and Simulations Needs for Grid Modernization”
Abstract: Power system analysis has long relied on large scale computer simulations for operation and planning of the grid. These simulations rely on a set of well-understood physical models and generally agreed upon simplifications, such as, the separation of transmission and distribution, ZIP models for aggregate loads, and so on. Recent trends in the grid requires a rethinking of the models and these underlying assumptions. Grid changes include: (a) the increasing number of power electronic interfaced devices both for renewable resources and for new loads; (b) the emerging importance of the analysis of the communication network for understanding operations; (c) a more actively controlled distribution system; and (d) new performance requirements for both reliability and resilience. Their are competing approaches to this need ranging from fully integrated models to independent simulators that share minimal information. This talk will review our approach in the research center CURENT using both software and hardware testbeds.

Understanding the Barriers of Rooftop Photovoltaic Adaption
Xiaojing Xu and Gerald Jones, University of Tennessee
Abstract: Rooftop Photovoltaic (RPV) or solar power generation is one of the most widely accepted renewable technologies and understanding the reasons and barriers to its adoption is one of the often-studied questions researched today. From researchers to policy makers understanding what causes people to adoption solar power or not will help encourage and influence the spreading of the renewable technology. Our multidisciplinary group leveraged a Machine learning and statistical analysis tools to help tackle a big data set known as Deep Solar provided by Stanford that identified the number and location of rooftop solar installations at the census tract level across the continental US. This study used census tracts as analysis units and investigated the major influencing factors among a variety of variables including policies, demographic features, population features, geography and climate, dwelling features, energy usage, energy price, commuting habits, etc. We compared the influencing factors in TVA-service area and a broader area. The effect of price was compared in areas with different levels of residential solar penetration, and varying levels of solar adoption incentive programs. Our findings indicated that things that many of the aforementioned can help indicate the level of solar adoption at the census tract level among other factors.
Bio: Xiaojing Xu has a Ph.D. in Experimental Psychology with a focus on social psychology and decision making. Her current lines of research include identifying the drivers of and barriers to adopting home energy management systems and renewable technologies, developing customer segments for tailored demand response programs and rewards, promoting office energy efficiency by examining the triad of individual, group, and building-related factors, and exploring the energy affordability issues of low-income communities.
Bio: Gerald Jones has BS degrees in Electrical Engineering and Computer Science from the University of Tennessee, Knoxville. He is currently working toward a masters in Computer Science with a focus on machine learning. His current research focus is analyzing the most influential and predicatively powerful factors related to various metrics of solar adoption across the US and from a state by state and regional perspective.
