Challenge 3

The Grid Optimization (GO) Competition Challenge 3 will start in December 2022.  It is not too late to enter.  Win up to $750,000. The first event will take place on Jan. 20, 2023. The second event will take place in March 2023. The third event will take place in June 2023; the fourth and final will take place in early September 2023.

The Grid Optimization (GO) Competition Challenge 3, will focus on the security-constrained optimal power flow (SCOPF) problem. It is part of a continuing effort begun with Challenges 1 and 2, to successfully discover, develop, and test innovative and disruptive software solutions for critical energy challenges and to overcome existing barriers. The broader goal of the of the GO Competition is to accelerate the development of transformational and disruptive methods for solving problems related to the electric power grid and to provide a transparent, fair, and comprehensive evaluation of new solution methods. In particular, the GO Competition seeks to identify innovative power system optimization and control methods that will accelerate the development and adoption of emerging technologies. Innovative solutions that are identified by the GO Competition will enable increased grid flexibility, reliability, and resilience while also significantly increasing energy security, providing greater energy efficiency, and substantially reducing the costs of integrating emerging technologies and resources into the electric power system in the United States.

Challenge 3 will focus on multiperiod dynamic markets including advisory models for extreme weather events, day-ahead markets, and the real-time markets with an extended look-ahead. These problems will include active bid-in demand and topology optimization.
