This work proposes a new method, called the Compensated Distributed Line Decoupling (CDLD), to decouple distribution networks among parallel processing cores in a real-time multi-core environment. Due to the short length of distribution lines, decoupling the network for real-time processing is challenging. Previous studies proposed the Stublines and State Space Nodal (SSN) solvers but both approaches have limitations and the proposed method addresses these limitations to implement improvements. Specifically, the CDLD method can be used as an enhanced Stubline decoupling, improving on its accuracy and transient response, or it can be combined with the SSN solver to improve its computational performance and remove bottleneck issues. The CDLD method was tested on three IEEE systems in real-time, and significant improvement was realized in network response and computational performance compared to the prevailing methods. The combined SSN-CDLD method proved to be the most promising approach for network decoupling
