Optimal Maximum Capacity Allocation Method for Multi-infeed Renewable Energy Cluster Based on Sensitivity Collaboration
随着新能源接入比例的不断提高,并网系统逐渐演变为多馈入系统且电网强度逐渐变弱,谐振问题将成为限制新能源渗透率提升的关键因素之一.为此,提出一种谐振约束下用于提升多馈入新能源集群最大接入容量的优化分配方法.首先,建立含工作点的并网逆变器阻抗模型,基于电网络理论获得了广义多馈入系统的聚合模型.然后,构建相角裕度关于集群容量的极值函数,并应用拉格朗日乘数法获得了一定容量下稳定裕度最大时集群阻抗灵敏度需保持一致的极值条件.在此基础上,面向谐振约束下区域电…查看全部>>
With the continuous increase in the accessing proportion of renewable energy,the grid-connected system gradually tends to be a multi-infeed system and the grid strength is gradually weakened.The resonance problem will become one of the key factors which limits the improvement of the renewable energy penetration rate.Therefore,with the constraints on harmonic resonance,an optimal allocation method is proposed to increase the maximum accessing capacity of mult…查看全部>>
