随着全球风电装机容量的不断增加，运行过程中暴露出越来越多的问题。这些问题之一与风速的随机性有关，导致风电预测的准确性较低。这就是为什么能量存储变得越来越重要。本文介绍了一种仿真工具，用于模拟并网风电场和通用储能单元的协作。该工具的目的是减少预测和实际风力发电量之间的差异。介绍完今天的预测方法，接下来详细介绍基于规则的模拟工具。使用匈牙利风电场的数据演示了该工具的操作。然后计算通用储能单元的额定功率和容量，该单元能够在 95% 的时间内将匈牙利风电场和所属储能的输出保持在预测功率的 ±50% 范围内。
As installed wind capacity of the world increases, more and more issues are revealed during operation. One of these issues is related to the stochastic nature of wind speed that results in low accuracy of wind power forecasts. That is why energy storage becomes increasingly important. In this paper, a simulation tool is introduced developed to simulate the cooperation of a grid-connected wind farm and a generic energy storage unit. The aim of the tool is to decrease the difference between forecasted and actual wind power production. After the introduction of today's forecasting methods, the rule-based simulation tool is detailed. The operation of the tool is demonstrated using data of the Hungarian wind farms. Rated power and capacity is then calculated for a generic energy storage unit that is able to keep the resulting output of Hungarian wind farms and the belonging energy storage inside the ±50% range of the forecasted power, 95% of the time.
