风电并网后电网调峰措施的经济性分析

为接纳大量风电并网运行,电网需采取各种调峰措施并评价措施的经济性。给出了确定用于平衡风电出力波动的电网可调峰容量的方法,阐述了接纳风电所采取的调峰措施,并对各种调峰手段进行经济效益分析。基于系统的安全运行要求、调峰措施、调峰容量、各种发电形式上网电价和化石燃料的消耗量提出了衡量以及评价调峰措施经济性的方法。以区域电网为研究对象,制定了调峰策略,为电网的节能经济调度提供参考依据,并对风电的持续健康发展提出了建议。

Economic Analysis on Peak Load Regulation Measure with Integration of Wind Farms

To accommodate large numbers of integrating wind powers,various peak regulation measures should be taken in power grid and be evaluated economically.In this paper,the load capacity regulating method of power system that is used to balance the output power of wind generation is presented,and peak load regulation measures to integrate wind power is discussed.Then,economic benefit of each peak regulation measure is analyzed,and the approach to balance and evaluate the economics of peak load regulation measures is proposed based on secure operation requirement of system,load regulation measures and capacity,electricity price of various forms of power generation,and consumption of fossil fuel.In the end,the peak load regulation scheme is presented for regional power grid,which is reference to energy-saving economic dispatching and sustainable health development of wind power.
