基于相关机会规划的风电并网容量优化分析

风能的随机性和间歇性强,所以与传统发电形式相比,风电场容量可信度低,如何计算系统中的最大风电并网容量是风电规划所面临的重要问题。基于相关机会规划理论,在保证系统安全运行的前提下建立了计算风电并网容量的优化分析模型,模型中引入了风电的发电能力约束,并考虑了风电场减出力控制措施的影响。该模型适用于不确定环境下的随机事件评估,基于IEEE39节点系统的风电并网容量优化结果验证了模型的可行性。

Optimization Analysis Model of Grid-connected Wind Capacity Based on Dependent Chance Programming

Compared with the conventional generation, the capacity credit of wind farms is very low because of stochastic and intermittent characteristics of wind energy and therefore it has great effects on the integration of wind farm into power system. This paper proposes a new optimization model for calculation of the proper integrated wind capacity based on dependent chance programming theory. In the model, the constraints of system safety operation and the electricity generated capacity of wind farms are considered, and the control method for wind farm operation is taken into account as well. The proposed model is suitable for the optimization in uncertainty environment and its utility is validated with the wind farm integrated into IEEE-39 power system.
