Prof. Street's contributions to the state-of-the-art in Unit Commitment and Transmission Planning

Prof. Street has made pioneering contributions to the state-of-the-art representation of uncertainty in unit commitment (UC) and transmission planning problems. By efficiently integrating general n-K security criteria and renewable uncertainty in these problems using robust optimization, he provided computationally efficient and cost-effective models to co-optimize energy and reserves within these applications.

He published the first IEEE TPWRS paper on robust optimization applied to power systems operation [1] and paved the way for many subsequent works. This seminal work eliminated the need to explicitly represent all post-contingency states in the model to endogenously define reserve amounts integrated with the energy schedule. His paper applied duality theory to show that the n-K security criterion is essentially a robust optimization problem, bridging reliability standards with robust optimization theory and unlocking new methods to solve uncertainty-aware power-system problems. His leadership in this area is commendable. He has continuously contributed to both theory and practice by generalizing these ideas to a joint generation and transmission security criterion [2][3], incorporating renewable uncertainty [4], improving worst-case renewable scenario realism with a new data-driven spatial-and-temporal dependency representation approach [5], and linking industry practices with the state-of-the-art distributionally-robust methods through a novel conditional ambiguity set in transmission planning [6].

Prof. Street's pioneering works on efficiently integrating security criteria and renewable uncertainty into unit commitment and planning models [1]-[6] has profoundly impacted more than 900 direct citations. These works established a new paradigm for addressing uncertainty in power system operations and became foundational, influencing many subsequent studies and researchers that extended and applied his methods to various aspects of power system optimization. From the power-system operation and planning side to the physical and financial portfolio management in electricity markets, a large set of important works used and cited Prof. Street’s papers to support new ways to handle uncertainty in related applications efficiently. Finally, the contributions and significant improvements in the state-of-the-art methods and theory applied to uncertainty modeling in power system planning were widely acknowledged by the power system and operations research communities through important awards. Prof. Street is currently one of the top 3 Brazilian researchers contributing to power transmission planning and unit commitment in the top IEEE Transactions journals.
