Effect of Spectral Shift on Solar PV Performance

Mitchell Lee, First Solar

Abstract:

Photovoltaic module performance is defined at standard test conditions, which includes a defined spectral irradiance distribution. However, environmental conditions in the field often differ from the standard spectrum; this change in spectrum is known as spectral shift or spectral mismatch. Mitchell will discuss the impact of spectral shift on various PV technologies and presents models that have been proposed to characterize this effect when modeling PV system performance.

Speaker:

mitchell-leeMitchell Lee is an engineer at First Solar. He develops and validates models that are used to predict the energy generation of PV power plants. Prior to First Solar, Mitch was an energy data analyst at the Columbia University Earth Institute where he focused on PV micro-grids and better understanding the energy needs of the rural poor in developing countries.

Mitchell’s work has been published in Renewable Energy, Energy & Environmental Science, the IEEE Photovoltaics Conference, and the IEEE Global Humanitarian Conference. Mitch earned a BS in Mechanical Engineering from Union College, and a MS in Mechanical Engineering from Columbia University.

 

 

 

 

 

 

Zinc-air Batteries Gain Momentum in Long Duration Applications

Glynne Townsend, VP Business Development, North America, Fluidic Energy

Abstract:

Advanced energy storage technologies are proving to be optimal solutions for long duration applications and enabling strong momentum in long duration applications that have traditionally faced cost and lifetime obstacles including renewable integration, benefit stacking and off grid microgrids. Fluidic Energy invented and commercialized the first rechargeable and long duration Zinc-air energy storage technology, an optimal technology for long duration applications. With over 40 MWh energy storage and strong momentum, Fluidic Energy’s rechargeable Zinc-air technology is filling a void in the clean energy market unlocking commercial viability.  Furthermore, this session will cover how Fluidic solutions in these types of applications are going well beyond the chemistry itself to provide vertically integrated solution and a whole product approach.

SMART GRID

Transactive Energy Market

Paras Mandal, Director, Power & Renewable Energy Systems (PRES) Lab, University of Texas at El Paso

Abstract:

The key elements of the smart distribution systems, such as end-user consumers, distributed energy resources, storage systems, demand response programs and others, need to be actively involved in local coordination tasks for dynamic balancing of supply and demand. In this regard, Transactive Energy (TE) is an emerging concept that shows potential to coordinate the operation of an ever-growing number of intelligent devices and resources by treating economic and control signals of power system. The concept of TE in power grid is in its infancy, however, TE is an area of great opportunities to improve smart grid operations. This talk presents (i) a decentralized TE market mechanism to improve the efficiency, reliability, and performance of the electric power grid in the path towards a sustainable future and (ii) some of the value drivers for the deployment of TE systems. This talk will also highlight the importance of TE market mechanism to provide an interface for DSO and TSO in order to manage the increasing complexity of the grid effectively.

Sustainable System Assessment with Resilient Control Systems Metrics

Timothy McJunkin, Idaho National Laboratory

Abstract:

A relatively new area of research and development known as resilient control systems seeks the means to make systems, that may be complex and distributed, and have human as a necessary or required element of the control loop, maintain acceptable levels of performance in the presence of disturbances generated by nature or man. Current emphasis in resilient control systems is being applied to metrics to measure the relative “resilience” of various changes to the design of the system. For example, the impacts and benefits of adding distributed energy resources to distribution systems or applying advanced control algorithms. There is a strong relationship to how the consumer responds and with respect to how policy is enabled and how competition and cooperation in markets play out. Similar themes can be applied in the area of sustainability as technology is brought online. This talk will discuss distribution system metrics and discuss possible consideration to a more difficult problem of assessing the resilience of proposals for improving sustainability.

Mr. McJunkin is also a developer of educational research tools including the Grid Game developed for multidisciplinary course and training of policy makers.

 

 

 

 

 

Optimal Real-time Demand Dispatch in Smart Grids

Sumit Paudyal, Michigan Technological University

Abstract:

With the implementation of Smart Grid technologies, such as  sensors, smart meters, smart appliances, more than one-fourth of the US total electricity demand could be dispatchable. Coordinated demand dispatch of customers’ loads provides benefits to the customers and the grid both. A complete demand dispatch solution that benefits the customers and the grid involves a large scale optimization problem with underlying complex transmission and distribution grid models. A centralized approach to solve this problem is computationally involving in a practical sized grid with the consideration of comprehensive customer load models and the grid models that include discrete control variables. A practical way to solve this problem is to use hierarchical and distributed computing approaches, where information exchange occurs between the different levels in the hierarchy. This talk presents hierarchical framework to i) optimally dispatch electric vehicle (EV) loads in vehicle-to-grid interaction (V2G) and ii) optimally dispatch commercial building loads in building-to-grid (B2G) interaction. The case studies demonstrate the benefits of optimal demand dispatch of EV and building loads to the customers and distribution grid operation.

Enhanced representations of lithium-ion batteries in power systems models and their effect on the valuation of energy arbitrage applications

Apurba Sakti, Research Scientist, MIT Energy Initiative

Abstract:

We develop three novel enhanced mixed integer-linear representations of the power limit of the battery and its efficiency as a function of the charge and discharge power and the state of charge of the battery, which can be directly implemented in large-scale power systems models and solved with commercial optimization solvers. Using these battery representations, we conduct a techno-economic analysis of the performance of a 10MWh lithium-ion battery system testing the effect of a 5-min vs. a 60-min price signal on profits using real time prices from a selected node in the MISO electricity market. Results show that models of lithium-ion batteries where the power limits and efficiency are held constant overestimate profits by 10% compared to those obtained from an enhanced representation that more closely matches the real behavior of the battery. When the battery system is exposed to a 5-min price signal, the energy arbitrage profitability improves by 60% compared to that from hourly price exposure. These results indicate that a more accurate representation of li-ion batteries as well as the market rules that govern the frequency of electricity prices can play a major role on the estimation of the value of battery technologies for power grid applications.
