基于仿射可调鲁棒的非预期全场景可行机组组合
Non-anticipative All-scenario-feasible Unit Commitment Based on Affinely Adjustable Robust Model
摘要
Abstract
Non-anticipativity is a critical principle in power dispatching,ensuring that uncertain future parameters do not affect current decisions.All-scenario feasibility refers to the ultimate objective in power dispatching,where every possible realization of uncertain parameters has a corresponding feasible decision.These become vital in power dispatching,especially with integrating renewable energy sources introducing uncertainties.Thus,this paper explores the mechanisms of non-anticipativity and all-scenario feasibility,constructing non-anticipativity constraints and a finite scenario set that satisfies all-scenario feasibility.Based on them,this paper establishes a scenario-based all-scenario feasible unit commitment model with non-anticipativity to provide unit commitment solutions that satisfy all-scenario feasibility.Further,recognizing the computational challenges posed by the above model,this paper transforms the model using affine transformations and robust equivalent constraints.It introduces an affine-adjustable robust all-scenario feasible unit commitment model with non-anticipativity in decision-making.This model reduces the computational complexity and demonstrates advantages in solving efficiency.Finally,the paper conducts case studies using a modified IEEE-118 test system.These case studies thoroughly examine the importance of non-anticipativity in decision-making and the necessity of decisions fulfilling all-scenario feasibility in power dispatching,then evaluate the efficiency of the proposed affine-adjustable robust all-scenario feasible unit commitment model with non-anticipativity in the decision-making process.关键词
