Efficient hosting capacity computation using the bisection method for rapid grid capacity assessment

This paper introduces a novel approach for computing Hosting Capacity (HC) by employing the bisection method as an alternative to the traditional step method. The primary objective is to achieve nodal and global HC results with significantly reduced computation time while preserving the accuracy characteristic of the step generator method. This fast and reliable technique is particularly well-suited for the iterative calculations required by large energy utilities to determine the maximum grid capacity for integrating new loads and distributed energy resources. The proposed method leverages grid linearization, incorporating the concept of compensation admittance at each node. The validity and effectiveness of the bisection-based HC computation are demonstrated through a comparative analysis against classical step method results, confirming its accuracy and computational efficiency.
