Most common low voltage problems in distribution systems can be addressed by installing capacitors. But, how to optimally place and size the capacitors? And how would the capacitors impact the system due to harmonics and switching transients? In this article, we propose to address these questions.
The results showed that there is a voltage drop problem at the end of the system in the 10-bus system, and this voltage drop can be improved by capacitor placement. In addition, network losses can be reduced. In the 33-bus system, network loss reduction and voltage profile improvement can be seen.
Therefore, the optimal locations and sizes of capacitors in distribution systems can be formulated as a constrained optimisation problem. To solve this problem, the optimisation techniques are applied. Many optimisation techniques were applied to solve the optimal capacitor placement problem.
Simulations were implemented in two standard 10 and 33-bus systems. The results showed that there is a voltage drop problem at the end of the system in the 10-bus system, and this voltage drop can be improved by capacitor placement. In addition, network losses can be reduced.
Place capacitors at loads which consume significant reactive power. For example, place capacitor in an industrial plant which have less than 85% power factor and bus voltage less than 95% nominal. Combination between rule of thumb (so called 2/3 rule) and running series of power flow simulations to fine-tune the capacitor size and location.
The proposed procedure using the multistage method to find the optimal placement of capacitors is applied on three standard radial distribution systems. These test systems are 10-bus, 34-bus, and 85-bus standard distribution test systems. The results are compared with those obtained using other reported methods.
