TITLE: Top-k Merit Weighting PBIL for Optimal Coalition Structure Generation of Smart Power Grids
SPEAKER: Sean Lee, Department of Information Science
WHERE:Room G34, Owheo Building
WHEN: 1:00 pm, Friday 18 August
The cooperation of agents in smart grids to form coalitions could bring benefit both for the agent itself and the distribution power system. To tackle the problem as a game of partition form functions poses significant computing challenges due to the huge search space for the optimization problem. In this seminar, we present a stochastic optimization approach using the Population-Based Incremental Learning (PBIL) algorithm with Top-k Merit Weighting and a customized strategy for choosing the initial probability to solve the problem. Empirical results show that the proposed algorithm gives competitive performance compared with a few stochastic optimization algorithms.
