A recently granted patent (Publication Number: US12003102B2) discloses a method and apparatus for optimizing the placement of distributed generators in a radial distribution grid. The method involves identifying the grid's topology, determining performance parameters, calculating voltage deviations, real and reactive power flows, and establishing a lossless power flow model to determine the maximum hosting capacity of the grid. Based on this capacity and performance parameters, the optimal number of distributed generators is calculated and placed strategically at distribution buses to meet the set parameters effectively.

Furthermore, the patent details the process of determining voltage magnitude and phase angle deviations, real power flows, and reactive power flows based on the identified topology. It also includes instructions for calculating the maximum hosting capacity for each distribution bus and the aggregate hosting capacity of the entire grid. The disclosed method aims to optimize the placement of distributed generators such as solar panels, wind turbines, or diesel generators to ensure the radial distribution grid meets predetermined performance parameters efficiently. This innovative approach could revolutionize the integration of distributed energy resources into existing power systems, enhancing grid resilience and efficiency while promoting renewable energy adoption.
