报告内容:In this paper, we consider a class of multi-stage stochastic generalized Nash equilibrium (SGNE) problem, where the feasible decision sets of all players are coupled together by a globally shared affine constraint. Upon utilizing the variational SGNE (v-SGNE) as a refined solution, the problem is reformulated as that of identifying the zeros of a sum of monotone operators through the integration of nonanticipativity constraints, primal-dual analysis and an augmentation of variables. We first propose a v-SGNE searching algorithm based on forward-backward operator splitting methods for solving the two-stage SGNE. And we also show the convergence of the proposed algorithm for fixed step-sizes under some mild assumptions. Then we extend the proposed method and its convergence result to dealing with the multistage case. Numerical simulations are given for electric power market with bounded capacities, to illustrate the efficiency and performance of the proposed algorithm.
