以直流联络线运行方式优化提升新能源消纳能力的新模式
A New Mode of HVDC Tie-line Operation Optimization for Maximizing Renewable Energy Accommodation
摘要
Abstract
In the interconnected power grid with large-scale renewable energy,the renewable energy can be accommodated in a wider area if the adjustment capability of high-voltage direct-current (HVDC) tie-lines is well utilized.To this end,a new mode of HVDC tie-line operation optimization for increasing the capability of renewable energy accommodation is proposed.In the mode,the tie-line power is viewed as a resource to be optimized.On the premise of meeting all the requirements of the tie-line power adjustment,the renewable energy accommodation in the interconnected power grid can be improved by adjusting the tie-line power.A mathematical model of the HVDC tie-line operation optimization is developed with consideration given to various constraints on tie-line power adjustment,including the daily energy limit,the stair-like tie-line power curve constraint, and the constraint that no adjustment in the opposite direction of the tie-line power shall be made within a short period of time. Case studies are conducted based on the actual operational data of a transregional HVDC transmission channel in China.The results have validated the effectiveness of the mode proposed.关键词
