    摘要:

    配置储能是解决风电出力反调峰性和随机波动性的有效方式。针对风电场储能配置较少考虑储能的实际使用寿命对储能成本的影响,以及欠缺考虑风电并网的日前、日内阶段调度需求的整体性,文章考虑电储能的使用寿命损耗特点,建立了实际使用寿命年值模型;依据风电日前、日内阶段的调度需求特点,初步确定应用蓄电池和超级电容来满足日前、日内阶段的调度需求;在满足风电并网技术要求下,考虑日前、日内阶段风电调度需求的整体性,以风电场年运行收益为目标进行储能配置,构建了计及储能使用年寿命的风电场整体性储能优化配置模型。以某实际风电场为例进行仿真分析,验证了所提储能配置方法的有效性。文章配置方法可有效利用风电并网过程中日前、日内需求关联的整体性,可为风电实际工程储能配置应用提供一定指导。

    Abstract:

    Deploying energy storage is an effective way to solve the problem of negative peak regulation and random fluctuation of wind power output.In view of the energy storage configuration of wind farms, which does not consider the impact of the actual service life of energy storage on the cost of energy storage, and does not consider the integration of the day-day and day-day scheduling demands of wind power grid connection, this paper considers the characteristics of the service life loss of electric energy storage, and establishes the actual service life annual value model.According to the scheduling demand characteristics of wind power in the day-day and day-day phases, battery and supercapacitor are preliminarily determined to meet the scheduling demand of day-day and day-day phases.In order to meet the requirements of wind power grid-connected technology, considering the integrity of wind power dispatching demand in the day-day and day-day phases, the energy storage allocation was carried out with the goal of annual operating income of wind farm as the target, and an optimal allocation model of integrated energy storage for wind farm considering the annual service life of energy storage was established.An actual wind farm is taken as an example for simulation analysis, and the effectiveness of the proposed energy storage configuration method is verified.The configuration method in this paper can effectively utilize the integrality of day-day and day-day demand correlation in the process of wind power grid connection, and can provide some guidance for the application of energy storage configuration in actual wind power projects.
