“…The locations for placement of the capacitors were identified by FES and their sizes were evaluated using GA. The injection of harmonic currents included harmonics in the order of 3,5,7,11,13,17,19,23,25,29,31,35,37,41,43,47, and 49 at a nominal frequency 60 Hz, where 15% of each load (w i ) was a nonlinear load. A peak load duration (T) of 2190 hours was used.…”

In electrical distribution systems, shunt capacitors are installed in order to reduce system losses, to enhance the voltage profile, and to free up system capacity. Nevertheless, the installation of shunt capacitors in distribution systems with distorted waveforms will magnify the distortion level of harmonics if they are not set at appropriate locations relative to the harmonics. This paper proposes a hybrid method to determine the placement and sizing of shunt capacitors in distorted radial distribution systems, taking into account the presence of harmonic distortion with consideration of ambient temperature effects, (this technique consists of the fuzzy expert system approach and the Genetic Algorithm method). This hybrid technique is applied to an IEEE 34-bus radial standard distribution system as well as a real distribution system in the Saudi Electricity Company. The simulation results show that harmonic distortion considerably reduces and the efficiency of distribution systems increases with a reduction in power loss and enhancement of voltage regulation.

“…The researcher had demanded that the applied method minimized THD and confirm higher annual benefits in contrast with [117]- [119]. MSPSO algorithm was applied in [120] where the fitness function was a net yearly benefit, maximum THD of voltage, maximum voltage deviation, and a resonance constraint. A.M. Othman developed the EBFO technique that incorporates optimal SCBs sizing and sitting with thermal cable evaluation on a practical 110kV sub-transmission line [121].…”

The main goal of power utilities is to supply reliable and quality power to the end-users and fulfill their total demands at all possible locations. Most of the loads are connected in the distribution systems are inductive. The excessive reactive power demand over the distribution network causes tremendous reactive power losses and changes the voltage profile, hence the system's reliability. Shunt Capacitor Bank (SCB) is widely used in the distribution system for reactive power support, voltage profile, and system performance improvement. But there are some challenges to employ SCB in the distribution network; among them, ensuring the most optimum location and size is a big challenge to get the maximum benefits. Some existing techniques showed better loss reduction but needed either larger SCBs sizes or cause improper node voltage. In this research study, the first section provides an extensive literature review of optimal SCBs placement and sizing. Later on, a new technique called Combinatorial Method has been developed for sizing and sitting of optimal Shunt Capacitors to reduce the distribution loss significantly. The developed method was tested for different case studies using Indian practical 22-bus and IEEE-69-bus network. The results were compared with DSA, Fuzzy GA, and TLBO method and found better distribution feeder loss minimization and voltage profile improvement.

When the inductive reactive load is higher, it will cause a voltage drop, increase the power losses in the system, decrease the power factor and decrease the capacity of the electrical power distribution. To reduce the load of inductive reactive power, a capacitive reactive power source is needed by installing the capacitor with the optimal size and at the right location. The method used to determine the optimal size and location of fuzzy logic-genetic algorithm. The parameters used in this simulation are minimal channel power losses while still meeting the specified voltage limit, Vmin = 0.95 PU and Vmax = 1.05 PU. The test results show that the location of the optimal capacitor placement with fuzzy logic-genetic algorithm is on bus 11 and bus 12. The test result from the study of newton raphson power flow, determining the location capacitor with fuzzy logic and determining the optimal capacitor size with genetic algorithm takes about 4 minutes.
