Modified Power Flow Algorithm of AC/DC Power Network

In order to utilize the advantage of AC and DC network, an efficient and flexible hybrid power network can be configured and operated by connecting them together through an AC/DC converters. This paper proposes a modified power flow algorithm based on the Newton-Raphson method for hybrid power network with renewable energy sources to configure and operate a high-efficiency and robust AC/DC power network. The modified power flow algorithm was developed using the MATLAB tools, and was verified on a desktop computer. The performance of the proposed power flow algorithm was compared with PSCAD simulations and MATPOWER for various AC, DC and AC/DC power networks.
