Talk Title: Renewable Energy Integration and Data-Driven Risk-Averse Stochastic Optimization
Abstract:
Renewable energy has been increasingly penetrating into the power grid systems recently. Due to its intermittent nature, new challenges arise for power system operators to provide reliable unit commitment decisions to incorporate intermittent renewable generation, with the objective of ensuring system reliability while maintaining cost effectiveness.
In practice, the distribution of renewable energy output is unknown, and instead, only a set of historical data is available. This motives a theoretical study on data-driven risk-averse stochastic optimization. Starting from the given historical data set, we introduce a set of probability metrics to construct the confidence set for the unknown probability distribution through nonparametric statistical estimation. We accordingly formulate a risk-averse stochastic program (RASP) from the perspective of distributional robustness by hedging against the worst-case distribution within the confidence set and considering the corresponding expected total cost. In our study, for a specific metric, we can derive an equivalent reformulation for RASP, which explicitly reflects its linkage with a full spectrum of coherent risk measures under various risk-averseness levels. This reformulation result can be further extended to other interesting models in the stochastic programming literature including chance and stochastic dominance constraints. In addition, we develop a solution algorithm for the reformulation based on the sample average approximation method. We also perform convergence analysis to show that the risk-averseness of RASP vanishes as the data sample size grows to infinity, in the sense that the optimal objective value of RTSP converges to that of the risk-neutral one. Furthermore, we can show the âvalue of dataâ by analyzing the convergence rate of our solution approach for a family of metrics.
Finally, we apply the proposed solution framework to solve the reliability unit commitment problem with renewable energy integration, and the computational results show the effectiveness of our proposed approach.
This is joint work with Ruiwei Jiang and Chaoyue Zhao

CS Colloquium: Prof. Ameet Talwalkar (UCLA) - Scalable and User-Friendly Machine Learning in Apache Spark
Thu, Mar 05, 2015 @ 04:00 PM - 05:15 PM

Speaker: Ameet Talwalkar, UCLA
Talk Title: Scalable and User-Friendly Machine Learning in Apache Spark
Series: CS Colloquium
Abstract: Modern datasets are rapidly growing in size and complexity, and this wealth of data holds the promise for many transformational applications. Machine learning is seemingly poised to deliver on this promise, having proposed and rigorously evaluated a wide range of data processing techniques over the past several decades. However, concerns over scalability and usability present major roadblocks to the wider adoption of these methods. In this talk I will describe the MLbase project, which aims to address these concerns by developing machine learning functionality on top of Apache Spark, a popular cluster computing engine designed for iterative computation. I will first describe MLlib, Sparkâs scalable machine learning library that grew out of the MLbase project. I will also discuss higher level components of MLbase, focusing on the problem of hyperparameter optimization as a means to simplify the task of machine learning pipeline construction.
Biography: Ameet Talwalkar is an assistant professor of Computer Science at UCLA and a technical advisor for Databricks. His research addresses scalability and ease-of-use issues in the field of statistical machine learning, with applications in computational genomics. He led the initial development of the MLlib project in Apache Spark and is a co-author of the graduate-level textbook 'Foundations of Machine Learning' (2012, MIT Press). Prior to UCLA, he was an NSF post-doctoral fellow in the AMPLab at UC Berkeley. He obtained a B.S. from Yale University and a Ph.D. from the Courant Institute at NYU.
