Optimal Power Flow of Integrated Hydrogen-Electricity Energy System Based on Reduced-dimension Projection
摘要
Abstract
An optimal power flow calculation method based on the reduced-dimension projection is proposed to solve the problem of optimal power flow in the integrated hydrogen-electricity energy system considering the uncertainty of wind power.Firstly,the centralized operation model of an integrated hydrogen-electricity energy system considering the uncertainty of wind power is established and equivalently transformed into a deterministic model.Then,the deterministic model is decomposed into subproblems for each subsystem.The reduced-dimension projection method is used to project the operation space of each subproblem into a lower-dimensional space,and the projected operation spaces of each subproblem are reconstrcted into a new convex hull.Next,by solving the optimal problem under the constraints of the reconstructed convex hull,the values of the common variables under the optimal cost of the integrated hydrogen-electricity energy system can be obtained.Furthermore,using the values of the common variables under the optimal cost to solve each subproblem,the power flow of each subsystem under the optimal cost can be obtained.This method conceals private information during the solution process and avoids iteration.Finally,the proposed method is tested on 6-6-node and 40-118-node integrated hydrogen-electricity energy systems,and the effectiveness,optimality,privacy protection,and other advantages of the proposed method are verified.关键词
