“…Reference upgrades the dealing with break points in the BFS procedures. References stress the dealing with transformers in the BFS procedure. One of the main properties of the BFS procedure is that it needs a single inversion of the Thévenin matrix with relatively small dimension that is equal to the sum of meshes and DGs of PV types.…”

Summary The contemporary concept of Smart Distribution Grid motivates researchers to develop more and more efficient Distribution Management System (DMS) as the basic platform of this concept. This paper deals with power flow as the basic DMS calculation. Procedures for this calculation are usually classified as branch oriented [back/forward sweeping (BFS)] and bus oriented [current injection and Newton/Raphson derivatives]. The first class is favored in this paper. An industry grade generalized BFS (GBFS) procedure is developed for power flow calculation of unbalanced distribution networks. The most complex distribution networks—“irregular” mixed networks—are particularly stressed. In addition, a very simple dealing with inductive and capacitive couplings between parallel overhead lines is presented. It is proven that GBFS is superior in comparison with other power flow procedures tailored for distribution networks—its robustness is at least equal to the robustness of other procedures, but its efficiency is significantly higher.

“…In such cases, backward/forward sweep-based methods are widely used to solve the distribution power flow due to their robust convergence characteristics. 9 Therefore, the backward-forward sweep algorithm (with current summation method) was applied into the computational tool developed.…”

The interest in optimization problems involving distributed generation units has grown among undergraduate and graduate students since distributed generation unit connections have been encouraged around the world, requiring efficient power system analysis tools to solve them. The available open access tools are commonly focused on transmission network analysis. On the other hand, commercial tools adapted to radial networks do not allow the students to follow the intermediary calculations and learn with them. In many cases, the students have to develop their own computational tools, which is a time-consuming activity. This paper aims to fill the gap encountered by undergraduate and graduate students when they are performing their optimization problems involving distributed generation units, presenting the advantages of a new power flow tool focused on radial electrical distribution networks with high levels of unbalanced loads which require a three-phase power flow tool to be analyzed. The use of the proposed tool allows the students focus on their research, reducing the time spent on programming, and learning about power flow analysis applied to radial networks.

“…The effectiveness of the backward/forward sweep method in the analysis of radial distribution systems has already been proven by comparing it to the traditional Gauss-Seidel and Newton-Raphson methods. The backward/forward sweep method is an iterative method that is considered root node be the slack node with known voltage magnitude and angle [12]. The initial voltage for all other nodes is considered to be equal to the root node voltage and the power loss for all branches is equal to zero.…”

The Distribution Static Compensator (D-STATCOM) coupled with a transformer is connected in shunt with a distribution network. This paper presents the best locations and ratings of a D-STATCOM in a radial distribution network. For this purpose, the backward/forward algorithm sweep has been carried out to compute the realistic system operation states and evaluate the control performance of the D-STATOM. In this paper D-STATCOM is utilized for improved voltage profile and reduction in power losses. A numerical result based on 33 bus distribution network is given to show the computational performance of the Backward/Forward power flow algorithm with incorporation of the D-STATCOM model.
