Strategic Planning and Economic Operations of Electric Vehicle Charging

Advances in intelligent transportation systems, offer great promise to address these challenges and have the potential to revolutionize future transportation systems. In the last decade, the U.S. government has spurred efforts to boost the utilization of transportation electrification technologies, because of their low-pollution emissions, energy independence, and high fuel economy. The successful rollout of the transportation electrification is highly dependent upon the affordability, availability, quality and resilience of the services that our nation’s critical infrastructures can provide, such electric vehicle charging facilities

In this project, a systematic investigation is proposed focusing on strategic planning and economic operation of EV charging facilities in a highly interdependent electrified transportation infrastructure with multidisciplinary complexities. (Read More)

Optimal Dispatch and Eco-driving Aid System for Eletrified, Connected and Automated Vehicles

We propose an optimal pre-trip routing and in-vehicle real-time eco-driving aid system to improve energy efficiency and increase occupancy without compromising the safety and comfort of end-users. The proposed algorithms take full advantage of connected, automated and electrified vehicle technologies. We target at one important research question: “What V2V/V2I and automated vehicle applications beyond safety bring day one value to the road users and stakeholders?”

The Michigan Mobility Transformation Center (MTC) is a public/private partnership that aims to research, develop and deploy new mobility concepts, with a near-term research focus on both engineering and “beyond engineering” topics related to connected and automated vehicle technologies.

Key MTC resources include (i) the Mcity, a 32 acre test facility designed to enable connected and automated vehicle research and development; (ii) Fleet of connected vehicles and infrastructure already deployed in Ann Arbor, and (iii) Collections of field naturalistic driving data. (Read More)

Smart Operations of Microgrid and Net-Zero Energy Homes

Economic and environmental incentives, as well as advances in technology, are reshaping the traditional view of power systems. The aging and overburdened U.S. power grid has experienced five massive blackouts in the past 40 years. To address these challenges, Microgrids have emerged as a relatively new and promising solution to restructuring the current energy infrastructure and ensuring the reliability of energy supply. Technically speaking, a microgrid is a low-voltage distribution network that is located downstream of a distribution substation through a point of common coupling. Microgrids consist of a variety of components including distributed generators, distributed energy storage, and controllable loads. The unique characteristics and dynamics of Microgrid components present a unique challenge with regard to grid control and operation. (Read More)


The next-generation residential distribution system is a level playing field in terms of electricity transactions, where all residential customers have an equal opportunity. While legacy power system operations are solely driven by least-cost and reliability concerns, the Energy Internet innovations are completely reshaping the traditional views of our power generation, distribution, consumption, social environment, and business world. The proposed Energy Internet requires that our society move away from, or at least supplement, the traditional centralized generation, distribution, and consumption business model to one where every user can actively participate in the energy market. User participation is a major factor that has resulted in exponentially increasing innovation and ingenuity in the information technology sector (e.g., Amazon, eBay and Facebook). If the ‘‘Information Internet’’ was the engine that powered our country’s economic growth in the last thirty years, then a similar and even more powerful Energy Internet will accomplish even more in the next several decades. In this context, the proposed new electricity market framework is analogous to the stock market or the business model of internet consumer-to-consumer (C2C) commerce such as eBay. 

The proposed work is first known effort to advance fundamental knowledge of a next-generation retail electricity market framework with full residential customer (Energy Cells) participation. (Read More)

Big Data Framework for Smart Grid Applications

As the number of smart meters/sensors increases to more than hundreds of thousands, it is rather intuitive that the state-of-the-art centralized information processing architecture will no longer be sustainable under such a big data explosion. Hence, an innovative distributed data management system is urgently needed to facilitate the real-world deployment of a future residential distribution system. 

In this project, we investigate a radically different approach through distributed software agents to translate the legacy centralized data storage and processing scheme to a completely distributed cyber-physical architecture. We further substantiate the proposed distributed data storage and processing framework on a proof- of-concept testbed using a cluster of low-cost and credit-card-sized single-board computers. Finally, we evaluate the proposed distributed framework and proof-of-concept testbed with a comprehensive set of performance measures. (Read More)
