An analytical method was utilized to determine the optimal amount of compensating capacitors in the first stage, while a statistical approach was employed to assess the reduction in energy losses resulting from the capacitor placement in each of the network nodes.
Capacitors have been shown to be highly important devices for enhancing the voltage profile and reducing power network losses. These kinds of equipment can be beneficial in reducing the network’s range of harmonic voltages due to their natural filtering function.
The second most desirable solution is the first study, which shows the effectiveness of capacitors in loss reduction. The proposed solution of the second study has the highest cost, which confirms that it is more economical to utilize capacitors for loss reduction rather than harmonic compensation.
In the first study, optimal capacitor placement took precedence, resulting in a significant reduction in network losses by 326 kW, an improved voltage profile within the acceptable range of 0.9 pu to 1.1 pu, and a reduction in THD. However, the maximum IHD remained unsatisfied at 9.46% on bus 25 at the fifth harmonic.
In the second study, capacitors were allocated while considering harmonic limits, leading to enhanced voltage profiles and reduced THD, yet some buses exceeded the constraints, with a peak IHD of 5.06% on bus 26.
The cost of capacitors is considered as C Cap and the cost of network losses is considered as C Loss in the optimization criterion formulation. These costs are calculated using equations (11), (12), respectively. (11) C C a p = ∑ j = 1 NC K j c ∙ Q j c (12) C L o s s = K p ∙ P L o s s = K p ∙ ∑ h = 1, 3, ⋯ P L o s s h where
