| Summary: | The paper studies the optimization features of low-voltage electrical network modes
for energy-efficient power transmission. The main features of these networks are
the high values of the zero-sequence voltage unbalance factor and the mismatch
of voltage values with the necessary requirements. Therefore, balancing the loads
by phases and reactive power compensation are chosen as measures to improve
the listed network parameters. One of the main factors for the effective solution
of this problem is the determination of load balancing points and reactive power
compensation, as well as the required power of the devices used. To solve the
multicriteria problem of determining device connection points, an analysis of existing
objective functions is carried out. As a result, a target function is proposed that
includes costs, voltage losses, zero-sequence voltage asymmetry coefficient. When
solving the optimization problem with the help of the proposed objective function,
the voltage values and the voltage asymmetry factor at the consumer connection
points will be within the required limits. The results of a study of the optimization
function using the example of a model network are presented. The calculations
are carried out in two stages: the search for sensor's nodes, then their study for
optimality. All calculations are carried out in the MATLAB environment, taking into
account voltage losses and power. |
