电力系统消纳风电能力的准确掌握，对于风电场建设规划以及辅助实际运行的调度决策意义重大。风电消纳的效率分析给电网高效利用风电提供了理论支持，风电消纳效率主要是用来衡量扣除电网消纳风力发电的成本后，风电对于电网净减排的贡献率。本文以目前我国的电源结构作为切入点，采用机组组合的生产模拟方法，从成本上分析了电网消纳风电的费用构成。基于二次规划模型，从理论上推导出了电网消纳风电效率与系统运行方式、机组参数和电网消纳风能比例等因素有关。最后通过实验仿真验证了理论的有效性和实用性。

Accurately mastering the capability of wind power accommodation is conducive to construction planning of wind plants and provide aids to dispatching decision in actual operation. Wind energy efficiency is used to pro?vide the theoretical support which is known as an essential index to help the power grid to accommodate wind energy more effectively. The paper takes into account the current power structure and analyzes the cost components in wind accommodation by means of unit commitment. The paper reveals how wind energy efficiency changes with the oper?ation modes and parameters of units, and the wind utilization proportion. The results show that the rules, approa?ches, prediction needs are quite unique in a wind?coal intensive power grid. The paper provides theoretical evi?dences of wind?coal coordinating operation design. The method is significant for improving accommodated capacity of wind power and instructing power planning. The example results show the effectiveness and practicability.
