摘要

为同一地区多个风电场集约化配置大规模储能电站可减小总储能规模从而降低成本,对此提出一种计及多风电场相关特性的集中式储能电站容量优化配置方法。首先计及多风电场实际和预测出力数据相关特性,建立联合分布藤Copula模型;其次利用降维场景生成方法生成海量多风电场联合出力场景,聚类选取典型场景;然后将典型场景序列导入储能系统约束模型,计及跟踪计划处理惩罚和波动越限惩罚,对储能电站容量进行优化配置;最后以华中某地相邻两风电场实测数据进行算例分析,实现多风电场的集中式储能定容。结果表明该方法在兼顾电网要求的同时,能优化储能电站总容量,提升多风电场和集中式储能电站的总体经济性。

Abstract

Multiple provinces require wind power to be coupled with energy storage, and the high cost of energy storage stations limits their own development and that of the new energy industry. To reduce the total energy storage capacity and lower costs by configuring large-scale energy storage stations intensively for multiple wind farms in the same region, a centralized energy storage station capacity optimization configuration method is proposed, which takes into account the relevant characteristics of multiple wind farms. Firstly, based on the Vine Copula theory, a joint distribution model of the actual and predicted output of multiple wind farms is established. Secondly, a dimensionality reduction scenario generation method is used to generate massive joint output scenarios of multiple wind farms, and typical scenarios are selected by clustering. Then, the typical scenario sequence is imported into the energy storage system constraint model, taking into account tracking plan processing penalties and over-voltage penalties, to optimize the capacity of the energy storage station. Finally, an example analysis is carried out using the measured data from two adjacent wind farms in Central China, achieving centralized energy storage with a fixed capacity for multiple wind farms. The results show that under the conditions of meeting the requirements of the power system, this method can effectively reduce the total configuration capacity of energy storage stations and improve the lifecycle economics of the wind-energy storage system.
