摘要
为了提高火电机组深度调峰极限,挖掘其提升新能源消纳能力的潜力,构建了基于氢能的风-火耦合多能系统。建立了风-火耦合多能系统的设计框架,包括设计原则、系统组成及评价指标体系等,提出了富裕风电制氢支撑的风-火耦合多能系统的总体结构;考虑经济性、能源利用、"双碳"目标、可靠性这4个方面的影响因素,提出了风-火耦合多能系统的多尺度评价指标及其数学模型,并基于模糊层次分析-熵权法确定各指标的权重占比;以某地区拟建的风-火耦合多能系统结构设计为例,验证了所提方法的有效性,可为实际工程建设提供了一定的参考。
In order to improve the deep peak shaving limit of thermal power units and tap their potentials to improve the consumption capacity of new energy,a wind-thermal power coupling multi-energy system based on hydrogen energy is constructed.The design framework of wind-thermal power coupling multi-energy system is established,including design principle,system composition,evaluation index system,etc.The overall structure of wind-thermal power coupling multi-energy system supported by affluent wind power producing hydrogen is proposed.Considering the four influence factors of economy,energy utilization,"double carbon"target and reliability,the multi-scale evaluation index and its mathematical model of wind-thermal power coupling multi-energy system are proposed,and the weight proportion of each index is determined based on fuzzy analytic hierarchy process entropy weight method.Taking the structural design of the proposed windthermal power coupling multi-energy system in an area as an example,the effectiveness of the proposed method is verified,which provides a certain reference for practical engineering construction.
