In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
The allocation and sizing of capacitors in the suitability position reduce the real power loss and enhance the voltage profiles. Metaheuristic algorithms are an important technique for finding the best allocation and rating of capacitors.
Research results The placement of capacitors resulted in improved voltage levels across the distribution network. Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines.
Since the system condition is dynamic: change with the season, time of the day, and other special condition, the capacitor should be sized according to power factor criteria and such that it would provide an acceptable voltage regulation during most, if not all, such conditions.
Distribution systems commonly face issues such as high power losses and poor voltage profiles, primarily due to low power factors resulting in increased current and additional active power losses. This article focuses on assessing the static effects of capacitor bank integration in distribution systems.
The optimal sitting and sizing of combined DGs and fixed capacitors will be applied by using the algorithm. The multiobjective ideal placement of capacitors and DGs at different load levels using the proposed optimization technique would have to be applied. Whale optimization.
Electrolytic Capacitor Testing and Replacement Cheat-sheet
Here are some fundamental rules for replacing electrolytic capacitors in circuit boards. Replace with exact type if available. Replace with capacitor that has the same capacitance (uF – microfarad) as the original. Replace with capacitor that has the same voltage rating or higher. Use higher temperature capacitors when possible (105c).
