Insights from Pecan Street’s Data-Intensive Research on Customer Energy, Water and Appliance Use
Abstract / Description: 

For the past six years, Pecan Street has operated one of the nation's most data-intensive research investigations on residential electricity and water use, behavioral response and field performance of different measurement devices. Using smart meters, gateway devices and CT-collar systems, Pecan Street researchers have measured appliance-level electricity use every minute in nearly a thousand homes in 20 states, including measuring generation from rooftop solar panels in over 250 homes and home EV charging in over 70 homes. In late 2013, Pecan Street launched Dataport, which makes all of the data from this ongoing multi-year investigation available to the academic research community for free in an online searchable database. Dataport's academic Research Board has estimated Dataport to be the world's largest research database on customer end uses of electricity and water.

The presentation draws on original data from this research to provide preliminary insights and identify research questions related to consumer behavioral response, residential battery systems, electric vehicle charging, solar PV generation's alignment with customer use patterns and the role of data.

SmartGrid Seminar

TBA
Abstract / Description: 

Recent development of the smart grid significantly enhanced the level of automation in the distribution grids. With high level deployment of remote-controlled switches, distribution feeders can be restored efficiently after power outages. In this presentation, computational algorithms for utilization of smart meters, remote control capabilities, and feeder restoration will be discussed together with their practical implementations. The role of microgrids in distribution system restoration will be evaluated. Traditional techniques, however, are not designed for extreme events in the distribution systems. The same is true for widely adopted reliability indices. New thinking of system design and operation will be important for resiliency of future distribution grids.

Topic: 
Zero Marginal Cost Power Grid
Abstract / Description: 

The talk will focus on research at Florida/Inria on harnessing flexible loads to create virtual storage. The goal is to address volatility from high penetration of renewable energy from the wind and sun. It is argued that these resources come at essentially zero marginal cost, which is a major barrier to innovation. Solutions to this dilemma will be proposed; it is hoped that this will lead to constructive debate — especially in view of CAISO's current debates on the future of DSM.

Based on joint research with Profs. Ana Busic and Prabir Barooah

Integration of Energy Storage into the Microgrid at the University of California – San Diego
Abstract / Description: 

The flagship microgrid at UC San Diego (UCSD) is the most often cited microgrid within CA given the fact that it is the largest, most diversified microgrid at 42 MW and self generates 85% of its own electricity on an annual basis. Because of the unique testing capability on the UCSD microgrid, and experience with testing energy storage, UCSD was recently chosen by ARPAe to conduct economic valuation and testing of some of the most advanced energy storage systems under real world market conditions. The presentation will also include an overview of the unique economic valuation of ARPAe advanced energy storage systems and how testing protocols have been developed that will simulate how energy storage will operate in modern wholesale markets, including stacked applications. UCSD has developed battery-testing capability for both laboratory and grid connected conditions. This allows testing in a controlled isolated laboratory environment, as well as testing in grid connected conditions where the interaction of the energy storage systems with the grid connected devices can be observed and evaluated. Multiple test stands have been developed for both laboratory and grid connected conditions, allowing parallel testing to place of multiple battery energy storage systems. UCSD has developed charge/discharge profiles and duty cycles for energy storage that represent five use cases for energy storage applications using real time and day ahead wholesale and retail energy market data. The testing apparatus is capable of producing loading conditions and duty cycles representing these use cases. This approach allows achieving test results that represent a wide spectrum of use applications and allow determination of energy storage systems performance under a variety of conditions and allow identification of specific applications that specific battery chemistry and good battery configurations.

Security Trends and Challenges for the Smart Grid
Abstract / Description: 

Cyber and physical security are critical priorities for electric power utilities. The increasing complexity of the electrical grid and the growing sophistication of attackers drive the need for strong cyber security in all domains of the electric sector. It is a threat that is global in nature and affects every utility, from large state-owned utilities down to small co-ops. This seminar will review ongoing research in protective measures, threat and incident management, and situational awareness for the electric sector. It will also identify current research gaps that must be addressed to support the resiliency of the next-generation grid.

Transient Stability Analysis of an all Converter Interfaced Generation WECC system
Abstract / Description: 

In this talk, a transient stability analysis of an 18205 bus Western Electricity Coordinating Council (WECC) system has been carried out when all conventional sources have been replaced with converter interfaced generation (CIG). A novel positive sequence model of the converter based sources has been developed in commercial transient stability analysis software. A simple and computationally economical model of the converter has been developed while ensuring a reliable representation of the detailed converter behavior. This model has been implemented as a user defined model in commercial positive sequence software such as PSLF. The behavior of the proposed model in positive sequence has the same form as the behavior obtained from detailed point on wave simulation. In this 100% CIG system, the only rotating machines directly connected to the network are wound rotor induction generator wind turbines and induction motor loads. The inertia contribution of these rotating devices is small. With close to zero inertia in the system, the dynamic performance of the system under different contingencies is examined and discussed. The analysis conducted demonstrates that while such a futuristic system can survive certain contingencies, well designed coordinated wide-area converter control action may have to be incorporated to enhance the reliability of the system. The examination of the importance of modeling the source behind the inverter due to practical limitations on the size of the dc bus capacitor is also considered emphasized.

Topic: 
Enabling the Grid of the Future
Abstract / Description: 

Electrical power distribution system of the future requires innovations. Some of its key technological and economic challenges lie in the attempt to: make electricity affordable throughout the world, allow local/distributed and time-varying generation, allow storage and load to be seamlessly integrated independent of utility, utilize modern power electronics, use networked distributed computing to provide the dynamic load-supply balance and stability, provide pay-as-you-go payment system for real-time market transactions.

I will present one perspective that touches upon different pieces of the overall solution stack: hardware design, safety, firmware, distributed intelligence, stability and control, economically optimized power distribution and trading mechanisms, systems architecture and communication, etc. Then, I will concentrate on our optimization framework for general AC/DC smart grids, based on the sequential convex programming, and its connection to the "faster" controls that ensure the grid's robustness to noise and unpredicted changes. This will include a discussion on distributed solutions that are based on the proximal message passing, and the properties of our implementation: physical stability, economic optimality of the resulting operating regime, robustness, and scalability with respect to the system size (number of devices attached to a grid), etc.
