The optimal capacitor placement is defined by determination of the number, location, type and size of the capacitors installed in the radial distribution network. In such problem, different objective functions may be defined.
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.
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 aspects of the power flow model which are important to capacitor allocation are: Transmission grid is generally modeled as a swing bus feeding the main distribution transformers. In a relatively large distribution system, single phase feeders are generally lumped and modeled as 3 phase loads and similarly for industrial plants.
Research methodology This research is a quantitative research, where measurements, simulations and numerical data are used to evaluate the effects of integrating capacitor banks into distribution systems. The focus is on measurable outcomes such as power flows, voltage levels and active power losses.
