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.

SmartGrid Seminar: Deepak Divan

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.

SmartGrid Seminar: Optimization, Inference and Learning for District-Energy Systems

Topic: 
Optimization, Inference and Learning for District-Energy Systems
Abstract / Description: 

We discuss how Optimization, Inference and Learning (OIL) methodology is expected to re-shape future demand-response technologies acting across interdependent energy, i.e. power, natural gas andheating/cooling, infrastructures at the district/metropolitan/distribution level. We describe hierarchy ofdeterministic and stochastic planning and operational problems emerging in the context of physical flows over networks associated with the laws of electricity, gas-, fluid- and heat-mechanics. We proceed to illustratedevelopment and challenges of the physics-informed OIL methodology on examples of: a) Graphical Models approach applied to a broad spectrum of the energy flow problems, including online reconstruction of the grid(s) topology from measurements; b) Direct and inverse dynamical problems for timely delivery of services in the district heating/cooling systems; c) Ensemble Control of the phase-space cycling energy loads via Markov Decision Process (MDP) and related reinforcement learning approaches.

SmartGrid Seminar: Emerging Technologies and Their Impact on the Grid

Topic: 
Emerging Technologies and Their Impact on the Grid
Abstract / Description: 

As rooftop solar, electric vehicles, and residential battery storage continue to become more and more commonplace, they can have significant impacts in the way the Energy Grid operates. By embracing these new technologies, PG&E is helping to create a vision for what a next generation energy company will look like and seeking to answer key questions such as: Is energy storage changing the way in which utilities operate the grid? What is needed for new technologies, such as residential battery energy storage, to go mainstream? What are some of the key factors driving the inevitable transition from a one-way grid to a two-way grid?

This presentation will focus on both the technology changes happening to the energy space as well as some of the technology advancements helping to reshape how the energy grid engages with these changes. It will cover these topics while exploring a case study of a recent pilot projects where PG&E, Tesla, GE & Green Charge teamed up on a project in San Jose to demonstrate how battery storage and rooftop solar connected to smart inverters can be used to support the electric grid during periods of high demand while providing participating residents and businesses with backup power and bill reduction. The project is a microcosm of what the grid will look like in the near future with the rapid adoption of distributed energy resources such as solar, battery storage & EVs.
