There are different methods for determining capacitor size and location. The most common method (intuitive) is based on rules of thumb followed by running multiple load flow studies for fine-tuning the size and location. This method may not yield the optimal solution and can be very time consuming and impractical for large systems.
In general, capacitor banks are installed in power systems for voltage support, power factor correction, reactive power control, loss reduction, system capacity increase, and billing charge reduction.
