Abstract
The topic issue of improving the power system operation
efficiency and increasing the maximum permissible current overflows
in the monitored sections is the focus of this article. To find a solution,
methods of analyzing the power system node's voltage sensitivity
are being used. A 14-node test circuit is applied to estimate the effi ciency of methods and the tolerability of possible errors. Sensitivity is
suggested to be estimated by example of a real network segment and
the use of generalized parameters of the electric network based on
saldo-conductance methods. It is shown that the reactive power com-
pensation units (RPCU) installed in the detected sensor nodes help
to improve the transmission limits in the monitored sections. Besides,
they help to reduce the active power losses in the most effective way.
Non-sinusoidal operating conditions are frequently present in modern power systems and can adversely affect the normal operation and performance of industrial equipment connected to the electrical grid. This paper presents a method for evaluating the relationship between the harmonic weights of voltage and current and...

The integration of D-STATCOM into the transmission system enables reactive power compensation in the SEP, with the aim of stabilizing voltage and reducing active power losses. Diverging from conventional models that depend on simplified linear assumptions, this work integrates full non-linear power-flow equations; thes...

The increasing penetration of inverter-based resources (IBRs) is changing fault behavior in modern power systems, thereby reducing the accuracy of conventional short-circuit calculation methods. This paper proposes a nonlinear optimization-based framework for short-circuit current evaluation that explicitly incorporate...

Introduction. Under conditions of variable and distributed loads, the issues of internal balancing in low-voltage distribution networks cannot be resolved without the use of effective algorithms for identifying distortion sources. Furthermore, networks of this voltage class are typically built based on main feeder sche...

Voltage instability remains a major operational challenge in large-scale transmission networks, particularly in developing power systems with increasing load demand. This paper proposes a coordinated on-load tap changer (OLTC) control strategy based on a Hybrid Particle Swarm Optimization–Grey Wolf Optimization (HPSOGW...

Calculation of power system bus load margins is an important task for ensuring of steady-state stability and preventing of voltage collapse. Traditional methods, such as the continuation power flow, face the problem of Jacobian matrix singularity in the vicinity of the limit point. This paper proposes a fundamentally n...
