Abstract:
The paper presents a new topological algorithm for the formation of nodal stresses of
complex networks of power systems. The first step of the described algorithm is the search and
determination of the values of all possible and specific trees of the graph corresponding to a given
network of the power system. The well-known advantage of the topological approach compared to
matrix methods, which allows one to obtain the final solution of non-linear equations of the steady
state, has led to the development of many methods and corresponding software implementations.
The paper provides a comparative analysis of the advantages and disadvantages of these methods.
The main computational complexity of these methods is the search for 2 trees for each tree, which
are obtained from it by dividing into two parts by removing any branch. A completely new
topological approach that does not require finding 2 trees was proposed by one of the authors. The
process of this method consists of the following steps: finding all possible graph trees, selecting
specific graph trees, calculating the network node voltage. The work offers a unique algorithm for
the implementation of these stages, which are implemented and tested at the software level. The
result of the execution of the software package is the calculation of the steady state of a complex
electric network using the distribution coefficients of the driving currents.
