Abstract

With the increasing grid penetration levels of wind power, there is a large need for the energy reserves for grid support during under-frequency conditions. Such energy reserves are created by operating the wind farm at non-optimum/deloaded operating points, as well as through storage of excess energy in Batteries. This paper provides technical and economic analysis of the above strategies and thus provides a case comparison of deloaded wind farm to that of wind-Battery system. A simplified Excel-based Proforma financial model has been developed to perform sensitivity analysis, as well as to obtain the impact of these strategies on the cost of energy.
风力发电与风力电池系统的经济性比较
随着风电并网水平的不断提高,在低频条件下需要大量的能源储备来支持电网。这样的能量储备是通过在非最佳/负载工作点运行风电场,以及通过在电池中存储多余的能量来产生的。本文对上述策略进行了技术经济分析,并给出了风电场减载与风电池系统减载的案例比较。开发了一个简化的基于excel的形式财务模型来进行敏感性分析,并获得这些策略对能源成本的影响。
