Rick Blum's research focus is on using Signal Processing and Communication theory to solve problems related to smart electrical grid systems. In one set of investigations, his group has been using hypothesis testing to detect failures and intrusions in smart grid systems. A smart electrical grid system implies the use of sensors at many nodes of the network. Each sensor gauges critical quantities and uses communication links to send these measurements to a control center. These measurements should be consistent with accurate mathematical models for these smart grid systems. Here, Prof. Blum's research attempts to detect failures or intrusions by detecting changes in the mathematical model describing the smart grid system that imply physical changes in the system or alteration of measurement packets. The results are new hypothesis testing methods which perform nearly as well as an unachievable optimum genie-based test that knows the exact value of the change in the mathematical model. Recent investigations imply that existing measurement devices, currently installed in the existing grid, can sample fast enough to achieve nearly identical performance to systems which sample much more rapidly in many scenarios of practical interest.

More recently, Prof. Blum has been studying joint design of the communications and the processing typically employed in the networks monitoring a power system. For example, his group has been examining the impact of imperfect communications on power flow calculations. Resource allocation and optimum processing of the original measurements are studied to achieve the most accurate calculations.

Larry Snyder's research uses tools from operations research (OR) to address a variety of optimization problems related to smart grids. His research group is developing optimization models and algorithms for dispatch and scheduling problems within the grid (both for service providers and for consumers) in order to design or react to demand-response programs, pricing structures, and other pricing signals that service providers use to shape load profiles. Another avenue of research involves location and dispatch of electricity storage devices (e.g., batteries) in the grid in order to level both the supply and the demand of electricity. Dr. Snyder’s smart grid research draws on his research expertise in mathematical models for supply chain management. His research on stochastic facility location and multi-echelon inventory optimization problems finds natural analogies in network design and storage optimization problems in smart grids.

Parv's research interests are in the areas of network security and privacy. His research group uses tools from information theory and signal processing to analytically study the relationships among privacy and performance that arise in smart electrical grid systems. Significant information about consumers' daily activities is required to fully realize the benefits of smart metering and demand response systems, and this could be construed by consumers as a violation of their privacy. By developing quantitative measures for privacy in these contexts and applying tools from statistical signal processing and stochastic control, Parv's group studies the trade-offs between achievable privacy and quality of service metrics such as user fairness, cost benefits and efficiency.
