| Abstract |
Nowadays, renewable energy sources are expanding for low-carbon green growth and Net Zero. With the increase in IDC, EV, and digital loads, attention is focused on the design and adequacy of Hybrid power grid that links LVDC and MVDC system to reduce conversion losses. Therefore, power flow and fault calculation are essential for designing and optimally operating the Hybrid power grid. In this paper, for steady-state analysis and protective relaying of Hybrid power grid, we propose a power flow and fault calculation technique. The proposed technique can be applied to AC, DC, and Hybrid power grid, and is implemented as program using the C language. Also, The superiority of the proposed power flow and fault calculation technique is proven through comparison with the simulation results of commercial S/W such as ETAP and PSCAD. |
