SmartGrid Seminar: Trends in Electric Power Distribution System Analysis at PNNL

Topic: 
Trends in Electric Power Distribution System Analysis at PNNL
Abstract / Description: 

Pacific Northwest National Laboratory (PNNL) originated and continues to maintain one of the two leading open-source distribution system simulators, called GridLAB-D, which has been downloaded 80,000+ times world-wide. While it continues to improve core functionality, PNNL is placing more emphasis recently on GridLAB-D as part of a development platform, improving its interoperability and opening the software up to more customization by researchers. This talk will cover two ongoing open-source development projects, funded by the U. S. Department of Energy, that incorporate and extend GridLAB-D. One of these projects is also expected to contribute distribution feeder model conversion tools for a new California Energy Commission project headed by SLAC. Highlights of the talk will include:

  • Transactive energy simulation platform, at tesp.readthedocs.io/en/latest
  • GridAPPS-D application development platform, at gridappsd.readthedocs.io/en/latest
  • Evole GridLAB-D's co-simulation support from FNCS interface, to a multi-lab interface called HELICS compliant with Functional Mockup Interface (FMI): https://github.com/GMLC-TDC/HELICS-src
  • Leveraging new capabilities for large-building simulation in JModelica, power flow analysis in OpenDSS, and transactive energy system agents in Python
  • Implementation and use of the Common Information Model (CIM) in a NoSQL triple-store database for standardized feeder model conversion
  • Comparison of different types of stochastic modeling for load and distributed energy resource (DER) output variability, and its impact on feeder model order reduction and state estimation
  • Special system protection example concerns on urban secondary networks with high penetration of DER

SmartGrid Seminar: Renewable Scenario Generation Using Adversarial Networks

Topic: 
Renewable Scenario Generation Using Adversarial Networks
Abstract / Description: 

Scenario generation is an important step in the operation and planning of power systems. In this talk, we present a data-driven approach for scenario generation using the popular generative adversarial networks, where to deep neural networks are used in tandem. Compared with existing methods that are often hard to scale or sample from, our method is easy to train, robust, and captures both spatial and temporal patterns in renewable generation. In addition, we show that different conditional information can be embedded in the framework. Because of the feedforward nature of the neural networks, scenarios can be generated extremely efficiently.

SmartGrid Seminar: Increasing Power Grid Resiliency for Adverse Conditions & the Role of Renewable Energy Resources and Microgrids

Topic: 
Increasing Power Grid Resiliency for Adverse Conditions & the Role of Renewable Energy Resources and Microgrids
Abstract / Description: 

System resiliency is the number 1 concern for electrical utilities in 2018 according to the CEO of the PJM, the nation's largest independent system operator. This talk will offer insights and practical answers through examples, of how power grids can be affected by weather and how countermeasures, such microgrids, can be applied to mitigate them. It will focus on two major events; Super Storm Sandy and Hurricane Maria, and the role of renewable energy resources and microgrids in these two natural disasters. It will discuss the role of microgrids in blackstarting the power grid after a blackout.

SmartGrid Seminar: Transmission-Distribution Coordinated Energy Management: A Solution to the Challenge of Distributed Energy Resource Integration

Topic: 
Transmission-Distribution Coordinated Energy Management: A Solution to the Challenge of Distributed Energy Resource Integration
Abstract / Description: 

Transmission-distribution coordinated energy management (TDCEM) is recognized as a promising solution to the challenge of high DER penetration, but lack of a distributed computation method that universally and effectively works for TDCEM. To bridge this gap, a generalized master-slave-splitting (G-MSS) method is proposed based on a general-purpose transmission-distribution coordination model (G-TDCM), enabling G-MSS to be applicable to most central functions of TDCEM. In G-MSS, a basic heterogeneous decomposition (HGD) algorithm is first derived from the heterogeneous decomposition of the coupling constraints in the KKT system regarding G-TDCM. Optimality and convergence properties of this algorithm are proved. Furthermore, a modified HGD algorithm is developed by utilizing subsystem's response function, resulting in faster convergence. The distributed G-MSS method is then demonstrated to successfully solve central functions of TDCEM including power flow, contingency analysis, voltage stability assessment, economic dispatch and optimal power flow. Severe issues of over-voltage and erroneous assessment of the system security that are caused by DERs are thus resolved by G-MSS with modest computation cost. A real-world demonstration project in China will be presented.

SmartGrid Seminar: Optimizing the Operation and Deployment of Battery Energy Storage

Topic: 
Optimizing the Operation and Deployment of Battery Energy Storage
Abstract / Description: 

While the cost of battery energy storage systems is decreasing, justifying their deployment beyond pilot or subsidized projects remains challenging. In this talk, we will discuss how to optimize the size and location of batteries used for spatio-temporal arbitrage by either vertically-integrated utilities or merchant storage developers. We will also consider other applications of battery energy storage, such as reserve and frequency regulation and how battery degradation can be taken into account in optimal dispatch decisions.

SmartGrid Seminar: From Sensors to Software: The role of Wireless in the Smart Grid

Topic: 
From Sensors to Software: The role of Wireless in the Smart Grid
Abstract / Description: 

Sensor-enabled embedded systems are redefining how future communities sense, reason about and manage utilities (water, electric, gas, sewage), roads, traffic lights, bridges, parking complexes, agriculture, waterways and the broader environment. With advances in low-power wide area networks (LP-WANs), we are seeing radios able to transmit small payloads at low data rates (a few kilobits per second) over long distances (several kilometers) with minimal power consumption. As such, LP-WANs have become both a target of study as well as an enabler for a variety of research projects. In this talk, I will describe our experiences in developing and deploying wireless sensing systems for energy-efficient building and smart-grid applications. I will start-off by discussing a number of hardware platforms and sensing techniques developed to improve visibility into buildings and their occupants. This includes new devices for occupancy estimation, demand-side management using electric water heaters and an assortment of low-cost and easy-to-install sub-metering devices. I then show how these devices can be easily integrated using an open-source platform called OpenChirp that provides data context, storage and visualization for sensing systems. Finally, I will go over a case-study where we electrified over 500 homes in rural Haiti with wireless smart-meters that now no longer require expensive and toxic kerosene for lighting.

Topic: 
Massively Distributed Control – An Enabler for the Future Grid
Abstract / Description: 

The power infrastructure is poised for dramatic change. Drivers include rapid growth in the deployment of exponential technologies such as solar, wind, storage, EVs and power electronics; improved economic, operational and energy efficiency; and higher grid resiliency under cyber-attacks and natural disasters. Data from the field shows severe limitations with using the traditional top-down centralized control strategy, and an alternate decentralized approach with dynamic control capability is needed. The 'future' grid will involve a full integration of the physical and transactive grids, and will be more dynamic, with bidirectional power flows, and a real-time market that all generators and consumers will be able to participate in. This will translate into unique requirements for autonomous distributed control using power converters distributed around the grid. The presentation will highlight several key issues and possible solutions for addressing them, showing that decentralized dynamic control using power electronics is very feasible and provides a path to a future grid that is more resource-efficient, flexible, resilient and can support higher levels of PV and wind energy penetration. The power infrastructure is poised for dramatic change.
