风电消纳全生产过程评价方法

Whole-Process Evaluation Methods of Wind Power Accommodation

不同地区不同风电场弃风限电的影响因素存在着较大的差异。随着风电管理日趋精细化,细化分析弃风电量成分,找到限制风电消纳水平的短板因素成了亟待解决的问题。基于新能源基础信息提出了风电消纳全过程评价方法,定量分析了"从风能到电能"全过程中,包括风能资源、设备可靠性、网架约束、电源结构和优先调度水平等多个环节产生的弃风电量,找到制约风电消纳的短板,实现风电消纳的全过程、多维度、精细化闭环管控。研究工作以弃风电量成分分析为纽带,实现了风电从发出到并网全过程的量化管理,能够指导风电场和调度机构找到弃风的主导因素,进而有针对性地进行整改,提升风电消纳水平,具有较高的推广应用价值。

Factors affecting wind energy curtailment of wind farms in different areas are very discrepant. It is necessary to find the most serious weakness of limiting utilization level through refined component analysis of wind power curtailment. Based on basic information of renewable energy, a whole-process evaluation method of wind power utilization is presented, and quantitative analysis of all aspects is illustrated to find the reason for wind power curtailment and the constraints of wind power consumption to achieve refined whole-process multi-dimensional closed-loop management. Through quantitative analysis, the dominant factors leading to wind power curtailment are put forward, and effective rectification measures could be taken to enhance wind power utilization level with high application value in China.
