New optimization framework uses Gaussian mixtures for robust chance-constrained problems

Researchers have developed a new method for distributionally robust linear chance-constrained problems, utilizing a Gaussian mixture model (GMM) to represent uncertainty. This approach improves upon finite-support distributionally robust (FDR) formulations by allowing the worst-case distribution to dynamically determine the number and location of mixture components, as well as their means and covariances within a continuous support. An adaptive cutting-surface algorithm has been created to solve these problems, which endogenously determines the parameters of the mixture components receiving mass. A case study on electric-vehicle charging-station energy allocation demonstrates the framework's effectiveness in meeting reliability targets. AI
