SmartGrid Seminar: Energy Efficiency: The Next Level

Topic: 
Energy Efficiency: The Next Level
Abstract / Description: 

Governor Brown and California's legislative leadership have called for a doubling of energy savings in existing buildings through 2030. In order to achieve these landmark goals and attract sufficient investment, major innovations are needed in energy efficiency policies, markets, and technology. This presentation summarizes a new initiative at Stanford University examining the framework needed for this "Next Level of EE" and a just released Stanford draft report, "Challenges, Opportunities, and New Tools for The Next Level of Energy Efficiency". A particular focus of the presentation will be the role of energy efficiency in a changing electric grid.

Topic: 
Electric Vehicles, plug-in hybrids, opportunity or threat for Electric Utilities?
Abstract / Description: 

It is a given that every auto manufacturer is building a full electric or plug-in hybrid model. Looking ahead, better batteries, faster charging options will drive accelerated adoption. Utilities have reacted by rolling out some charging stations or with limited programs to handle EVs on the distribution network. Utilities could play a proactive role and view this as an opportunity to consume significant portion of transportation energy revenues. Could this help them offset sinking demand and drive new revenue growth? Of course there remain challenges - insufficient vehicle-charging infrastructure, cost of batteries is still a concern, and a lack of consumer confidence in the new technology. However, forward looking utilities can address these challenges head on with attractive long term financing for at-home charging stations, partnering with EV manufacturers, consumer rebates for off-peak charging, and others to accelerate adoption and increase consumer confidence. In this presentation, we will discuss a case study how a progressive utility is conducting initial trials for demand & pricing based program for EV charging.

Topic: 
Data-Driven Management of Large, Distributed Energy Systems – The Case of Residential Solar Networks
Abstract / Description: 

Solar industry is at a critical point in its lifetime. The industry is experiencing exponential growth (residential solar market doubled in 2013). At the same time, as the large-scale deployment of residential solar systems was triggered by financial incentives starting in 2007, a large number of systems are entering their preventive and corrective maintenance periods. Typical residential solar contracts require solar companies to operate and maintain the systems for up to 20 years. With hundreds of thousands of systems distributed across several states and climates, the role of data in the operation of solar networks is becoming increasingly important.

This presentation explains data-driven operation of one of the largest residential solar fleets in the United States. The focus is on developing the data infrastructure and analytical methods to quickly and proactively identify operational issues and their root cause. The data-driven insights are fed back into operations, customer relations management, sales, marketing, product, and design teams. We demonstrate how advanced statistical methods can be deployed to predict production issues and hypothesize their root causes. In particular, we explain a novel method to estimate the long-term, gradual decrease in solar systems productivity, known as performance degradation. The process involves a full cycle of data collection, integration, hypotheses setup, field experiments, calibration, and visualization.

The audience of this talk includes data scientists, operations analysts, investors, and executives of large, distributed renewable energy networks.

Topic: 
Risk-Constrained Multi-Stage Wind Power Investment
Abstract / Description: 

When deciding on wind power investments, three major issues arise: the production variability and uncertainty of wind facilities, the eventual future decline in wind power investment costs, and the significant financial risk involved in such investment decisions. Recognizing the above important issues, this presentation proposes a risk-constrained multi-stage stochastic programming model to make optimal investment decisions on wind power facilities along a multistage horizon. The proposed model is illustrated using a clarifying example and a case study.

SmartGrid Seminar: Grid Modernization: Challenges, Opportunities, and Solutions

Topic: 
Grid Modernization: Challenges, Opportunities, and Solutions
Abstract / Description: 

Our aging grid infrastructure faces increasing challenges from multiple sources including greater demand variability, stricter environmental regulations and growing cyber security concerns. Advanced smart grid technologies provide possible solutions to tackle these challenges. Meanwhile how to best utilize these new devices and technologies such as PMUs and electric vehicles remains a challenge by itself. In this talk, I will address various topics which span a multitude of areas including demand response, stochastic optimization for renewable integration, microgrids and cyber security. I will present the technical issues in implementing these technologies and corresponding potential solutions.

SmartGrid Seminar: Modal Analysis of Power System Data

Topic: 
Modal Analysis of Power System Data
Abstract / Description: 

Reliable operation of the power grid relies on the real-time stabilization of an interconnected continentalscale network of dynamic components. These include everything from central-station thermal and hydro power plants to end-use loads. The natural uncontrolled responses to disturbances are oscillatory, and swings in voltage and power flows are evident in data from disturbances. Specific control systems are used to damp these natural oscillations that otherwise can result in large-scale blackouts. In order to design and tune controllers it is imperative to understand and anticipate the oscillations, and to develop high fidelity models that can represent this behavior.

In this seminar we focus on the modal analysis of power system data to study oscillations for three purposes:

1. Better the understanding of the oscillations actually present in the grid. (Off-line engineering analysis.)
2. Validation of models used to study the grid. (Operational Planning.)
3. Improve situational awareness by tracking system modes in real-time. (Operations.)

We will provide examples of oscillations observed in the grid in the context of these three objectives. We review the industry standard approaches for power system modal analysis and highlight their shortcomings in practice. They often require preprocessing the data, fine-tuning in model order, and give inconsistent results with related data sets. We suggest that the main attraction of these established methods is that they are computationally easy to use; the calculations require linear algebra. Based on our experience and dissatisfaction with these methods, we explore the use of nonlinear fitting techniques to estimate modes from data. With current computing power, computational barriers are low, and we show excellent results using a variable projection method.

Our method is currently in use by some power engineers to characterize observed oscillations in the West. We show results of using modal analysis to aid in power plant model validation. We discuss and present initial results for adapting our method to estimating modal behavior from ambient data in the grid, which is the focus of our on-going research in this area.

SmartGrid Seminar: Key Issues and Challenges in the Deepening Penetration of Demand Response Resources

Topic: 
Key Issues and Challenges in the Deepening Penetration of Demand Response Resources
Abstract / Description: 

We focus on the key developments in the implementation of demand response resources or DRRs, with special attention on their economics and policy aspects. The Federal Energy Regulatory Commission (FERC) forecasts an achievable 2019 DRR penetration range of 4 – 14 % of system peak load in the various ISO/RTOs under its jurisdiction. We discuss the three key factors driving the rapid growth in the DRR implementation: the rollout of the smart grid, the emergence of curtailment service providers or aggregators, and the developments on the demand response policy front. The large-scale implementation of advanced metering solutions to replace the legacy metering infrastructure and the deployment of appropriate technologies, devices, and services to access and leverage energy usage information are direct outcomes of the smart grid advancements. The creation of an important new class of market participants – the load aggregators – makes possible the deeper penetration of DRRs as viable competitors to supply-side resources. Recent policies, starting with the Energy Policy Act of 2005 and followed by FERC Order Nos. 719 and 745, and the various state-level initiatives have been instrumental in the removal of barriers to DRR participation and in bringing about the persistent deepening of DRR penetrations. We highlight some of the unintended consequences of FERC Order No. 745 and the challenges that deepening DRR penetrations present. While DRR curtailments result in lower loads, which reduce prices and emissions at specific nodes in the system during the curtailment hours, some portion of the curtailed energy is recovered in subsequent hours, resulting in impacts on prices and emissions in those hours — the so-called DRR payback effects. The recovery severely affects the economic benefits and emission reductions. Such outcomes underline the importance of the formulation and implementation of effective DRR policies.

SmartGrid Seminar: High Performance Computing for Power System Applications

Topic: 
High Performance Computing for Power System Applications
Abstract / Description: 

Control center operation is becoming more complex as new and often-conflicting reliability, economics, and public policy issues emerge. Computer simulations will be required to analyze larger and larger amounts of system data (of different types) and what-if-scenarios to derive succinct information for operators to make informed decisions. Existing control center applications are primarily based on the original digital computing infrastructure first designed in the 1970's. While some incremental improvements have been made over the past several years, control center applications do not take full advantage of computing power in their existing infrastructure or in the computing industry in general.

High Performance Computing (HPC) and advanced computer are used widely within the government and in selected industry applications to solve important problems of high complexity, providing a factor from hundreds to millions times improvements in time-to-solution over desktop computer solutions. This presentation will share and discuss some research work of applying high performance computing to solve power system problems.
