A Multi-time Scale Dispatch Model for New Energy Grid Connection Considering Generalized Short Circuit Ratio of Operation
摘要
Abstract
To ensure the stable operation of power system dur-ing large-scale new energy grid connection and reduce the in-stances of wind or solar energy curtailment,firstly,an analysis was made on methods for power fluctuation suppression in the new energy grid.Additionally,the generalized short circuit ra-tio of operation,a parameter for AC power grid strength evalu-ation after new energy being connected to the grid with arbit-rary power,was introduced.Secondly,a dispatch model for new energy grid connection considering three time scales:day-ahead,intra-day and real-time,was presented.Furthermore,a multi-time scale new energy grid connection capacity optimiza-tion models was established with the objective functions of minimum operation dispatch cost,maximum operation general-ized short circuit ratio,and the minimum fluctuation of joint output power.Finally,taking the system consisting of thermal power units,new energy stations,energy storage power sta-tions and high energy loads as an instance,the effectiveness of proposed strategy and model was verified through simulation.关键词
