DIgSILENT PowerFactory Tutorial: Optimal Capacitor Placement – IEEE 14-Bus Distribution System | Lecture 45 In this lecture, the Distribution Network Optimization Toolbox in DIgSILENT PowerFactory is applied to determine the optimal placement and sizing of shunt capacitors on the standard IEEE 14-bus test system. Voltage deviations identified through initial load-flow studies are addressed via a techno-economic optimization that simultaneously minimizes active power losses, capacitor investment and operating costs, and voltage-band violations. The tutorial provides a complete, step-by-step workflow: • Definition of feeders and selection of candidate terminals within the distribution network model • Configuration of optimization parameters, including voltage limits, energy cost rates, and a library of available capacitor banks with specified reactive power ratings and annual operating costs • Execution of the optimization in report-only mode to evaluate candidate solutions and quantify expected annual savings • Interpretation of results demonstrating substantial reductions in power losses together with improved voltage profiles • Optional direct installation of the recommended capacitors into the network model for subsequent studies This practical session equips power system engineers, utility planners, researchers, and graduate students with the skills to implement reactive power compensation strategies that enhance voltage regulation, reduce operational expenditure, and improve overall distribution network efficiency. By the end of the tutorial, viewers will be able to replicate the methodology on their own distribution system models and adapt the approach to real-world planning and operational studies.
