Research on Three-Stage and Multi-Mode Operation Optimization for Large-Scale Multi-Energy Complementary New Energy Bases
摘要
Abstract
[Objectives]In large-scale multi-energy complementary bases,there are multiple types of resources,significant fluctuations in new energy output,complex operating conditions,and diverse demands of owners,leading to great challenges in the actual operation optimization.Therefore,it is necessary to design and develop operation scheme of the wind-solar-thermal-storage coupled system according to engineering practice.[Methods]The operation model of large-scale new energy bases is established.Taking economic efficiency,carbon emission,load fluctuation rate,and new energy accommodation rate as the core optimization objectives,this study examines the three-stage multi-mode operation optimization scheme by comprehensively considering various operation requirements and equipment flexibility under different time scales.Combined with actual engineering cases,the typical days of the year and each season are analyzed to verify the effectiveness of the scheme.[Results]The dispatching method can effectively balance multiple optimization objectives,give consideration to equipment flexibility and diverse requirements,and improve the economic efficiency and operational friendliness of large-scale new energy bases.[Conclusions]The proposed scheme can effectively solve the multi-mode and multi-stage problems of large-scale new energy base operation optimization.It is suggested that the operators sign power export curve contracts based on the output characteristics of new energy in different seasons to improve the economic efficiency.The research results can provide engineering case reference and technical support for operation of the same type of large-scale new energy bases.关键词
