配电网中发电机组的并网是智能电网领域的主要研究课题之一。各国政府正在支持将中小型发电机直接连接到配电网，但随之而来的能源生产商数量的增加带来了一些技术问题。对于配电网的规划和运行，根据电能质量标准的限制来估计最大可安装发电量是很重要的。近年来，已经提出和设计了几种用于评估托管容量（HC）的方法，以考虑到与网络的可靠操作相关的不同方面。然而，许多方法都没有考虑分布式电源的电网分配的影响，特别是它的位置未知的发电厂实现之前。本文介绍了一种新的解决方案来计算HC的基础上的网络拥塞的风险。除了经典的电压和电流约束，该方法还集成了分布式发电的随机分配，并分别评估其对HC值的影响。
The integration of generation units in distribution grids is one of the main research topics in the field of smart grids. Governments are supporting the connection of small/medium size generators directly to the distribution network, but the consequent growing number of energy producers poses several technical issues. For the planning and operation of a distribution network it is then important to estimate the maximum installable generation according to the limits imposed by the power quality standards. In the recent years, several methods for the evaluation of the Hosting Capacity (HC) has been proposed and designed in order to take into account different aspects related to the reliable operation of the network. However, many methods are not taking into account the effects of the grid allocation of distributed generation and, especially, the unknown position of it before the power plants realization. The paper describes a novel solution to compute the HC on the basis of the risk of network congestion. In addition to the classical voltage and current constraints, the proposed approach also integrates the stochastic allocation of distributed generation and separately evaluates their impact on the HC value.
