Multi-energy flow calculation based on energy cell and parallel distributed computation

Jianshu Yu et al.

Summary: This paper proposes a parallel distributed computing method for multi-region IES, dividing large-scale IES into several energy cells based on the principle of energy cell and ensuring system convergence through virtual nodes. An extended Jacobian matrix is constructed in energy cells to calculate multi-energy flow, and decoupled energy cells are computed in parallel through limited information exchange of virtual nodes. The proposed method shows better calculation efficiency and accuracy compared to integrated and decomposed methods in two case studies.

Partitional Decoupling Method for Fast Calculation of Energy Flow in a Large-Scale Heat and Electricity Integrated Energy System

Suhan Zhang et al.

Summary: As the scale and complexity of the HE-IES system increase, it is crucial to accurately calculate energy flow. A partitioning decoupling method is proposed to address non-convergence issues, along with a unit conversion method for extreme scenarios, leading to efficient energy flow calculations.
