“…It is important to remark that the circuit schematic in Figure 1b can be easily described via the MNA [23,25], which represents one of the most established formulations for the solution of linear and nonlinear circuits, since it is currently used in a number of commercial simulation software such as SPICE. Specifically, according to the procedure in [25] the MNA allows analyzing the circuit in Figure 1b from topological inspection only, leading to the following matrix form:…”

“…The approach is simple and general, and applies to any kind of network, including meshed structures. It is important to point out that the proposed contribution shares the idea of using a circuit based approach which has already been proven to be general and robust in terms of convergence [23]. The proposed method is a viable alternative that can be readily applied to the number of alternative applications, including the co-simulation of multi-energy networks, possibly including gas distribution systems [27].…”

“…As a result, it converges for weakly meshed configuration only under some specific assumptions, as pointed out in [21]. A different formulation of the power-flow analysis for both power transmission and distribution networks by means of a circuital interpretation of the network and the application of classical tools for circuit analysis are instead presented in [22][23][24], offering a general solution with improved convergence for very large structures including weakly and heavily meshed structures.…”

This paper presents an alternative solution for the power-flow analysis of power systems with distributed generation provided by heterogeneous sources. The proposed simulation approach relies on a suitable interpretation of the power network in terms of a nonlinear circuit in the phasor domain. The above circuit interpretation can be solved directly in the frequency-domain via the combination of a standard tool for circuit analysis with an iterative numerical scheme, providing directly the steady-state solution of the power-flow of a generic distribution network. At each iteration, the resulting circuit turns out to be composed by two decoupled subnetworks, a large linear part and a set of smaller nonlinear pieces accounting for the load characteristics, with evident benefits in terms of the computational time. The feasibility and strength of the proposed simulation scheme have been verified on a large benchmark consisting of the IEEE 8500-node test feeder. Then it is applied to the statistical simulation of a power network accounting for the variability effects of renewable generators. According to the results, the proposed tool provides an effective alternative to the state-of-the-art approaches for power-flow analysis further highlighting the benefits of the application of well-established tools for circuit analysis to power-flow problems.

“…In [16] it is demonstrated that the advantages of BFS methods are especially shown at distribution levels. However, some authors agree that the BFS algorithms show problems such as topological limitations and lack of generality (inefficient modeling of large systems, arbitrary topologies and connections of some devices, as transformers) [17].…”

A Backward/Forward Sweep (BFS) algorithm for power flow calculations adapted to matrix formulation in the αβ0 reference frame is presented in this paper. The novelty of the work is the definition of a BFS solver with the following characteristics: matrix formulation in αβ0 frame, valid for unbalanced three phase or single phase systems and capable of handling transformers and distributed generators; Slack, PQ or PV nodes. The matrix formulation avoids the difficulties of load-flow methods presented in the literature: lack of generalization for arbitrary network topologies and transformer connections; the αβ0 stationary reference frame makes the algorithm easily applicable to distribution systems; and finally, the BFS algorithm is an efficient, robust and fast solver. The IEEE Node Test Feeders will be used to provide test systems under several configurations. Comparison to a direct algorithm will demonstrate the improvements in robustness, efficiency and computation time.
