Load Flow Analysis For AC/DC Distribution System Planning

The AC/DC distributed network’s power converters make it complex, but necessary, to establish a power flow methodology. The representation of the Backward-Forward Sweep technique to address the load flow for a radially oriented AC/DC distributed network. For this reason, a pu (per unit) current, voltage, and power model is initially used to describe the $3-\varphi$ PWM rectifier, 3- $\varphi$ PWM inverter, and DC/DC power converter device. This radial network layout provides the AC and DC bus classification to understand the distribution network. Integration of many controlling parameters of the previously stated converters is also given in this paper. The Backward Forward Sweep Method’s feasibility with power converters has been proven on a radial test network for AC/DC distribution. The test findings show that the BFS technique is accurate and feasible, especially when it comes to distribution network issues. It also shows that it is reliable in controlling the different controlling parameters of power converters to deliver efficient power flow on AC/DC networks.
