摘　　要：静态电压的升高是限制分布式发电渗透率水平的最主要因素。一般通过潮流计算来确定分布式发电的最大渗透率相当繁琐。提出了一个建立在线性化电力系统模型的电压灵敏度基础上,能在不引起电压越限的情况下直接确定分布式发电提供给每个系统节点最大有功功率的新方法。在70节点的分布式电网中对本方法进行验证,结果表明此方法能准确计算分布式发电的渗透率水平。Static high voltage rise is the main factor limiting the permeability of distributed generation（DG）. The con- ventional application of load flow calculation in determining the DG maximum penetration is rather complicated ; there- fore, this paper proposes a new method, based on the voltage sensitivity of linearized power system model, to directly determine the maximum active power of each system node input by DG without causing the voltage overshoot. This method has been tested in a 70-node distributed power network, and the results show that this method can accurately calculate the penetration of distributed generation.
