连续时间调度方法在电力系统灵活运行中的应用综述OA

[Objective]To enhance the representation of intra-interval power fluctuation and the allocation of flexibility resources,this paper provides a systematic review of the applications and existing challenges of continuous-time scheduling methods for flexible power system operation.[Methods]First,the mathematical formulations and solution paradigms of discrete-time and continuous-time scheduling are compared.Then,representative applications and problems are reviewed,organized according to four key domains:generation,transmission,storage,and demand.Finally,common challenges are synthesized from a mathematical point,and potential theoretical development directions are summarized.[Results]In continuous-time scheduling,decision variables are modeled as continuous trajectories,and constraints involve derivatives,integrals,and differential equations.The main solution paradigms include optimal-control-inspired methods and Galerkin-projection-based approaches.Shared difficulties mainly arise from modeling uncertainty in continuous time,solving nonconvex constraints such as unit commitment and charge-discharge exclusivity,and handling differential-equation constraints.[Conclusions]Based on these findings,this paper outlines future application trends and follow-up research topics of continuous-time scheduling in multi-timescale scheduling coordination,planning assessment,and market mechanism design.
