摘要

风电效能是用来衡量扣除电网消纳成本后风电净减排贡献率的指标，是指导电网有效利用风电的关键指标。文中立足于国内以煤电机组为主的电源结构，采用基于机组组合的生产模拟方法，分析了风电消纳成本的构成，从机理推导和仿真验证两方面得出了风电效能随运行方式、机组参数和风能利用比例等因素的变化规律。研究表明，在煤电占优网络中风能高效利用在主导机理、协调模式、预测需求上都存在其特异性。文中为多尺度风火协调运行框架设计提供了理论依据。

Abstract

Wind energy efficiency（WEE）is used to estimate the net contribution of CO2 emission reduction from wind-generated electricity，which is an essential index to measure the efficiency of a power grid to accommodate wind energy.This paper takes into account that Chinas power grids mainly consist of coal-fired units，and it analyzes the cost components in accommodating wind power by means of unit commitment.This paper reveals how WEE changes with the operation modes and the parameters of coal-fired units，and the wind utilization proportion both in theory and by case study.The results show that the rules，approaches，prediction needs are quite unique in a coal power plant intensive grid.In addition，theory basics of wind-coal coordinating operation is provided in this paper.
