A novel optimal capacitor planning (OCP) procedure is proposed for large-scale utility power distribution systems, which is exemplified on an existing utility circuit of approximately 4,000 buses. An initial sensitivity analysis is employed to intelligently reduce OCP computation time and maintain quality of optimal configurations. Three
In radial electric power systems, the bus with inflowing power is the one considered for capacitor placement. The sequence in which the buses are to be considered for compensation is decided by the descending order of the loss sensitivity factors.
The importance of the research lies in the importance of its topic, as Proper capacitor placement helps maintain the voltage levels within desired limits throughout the distribution network, ensuring stable and reliable power supply, and minimizes voltage drops across the distribution lines, improving the overall voltage stability of the system.
Capacitor placement in distribution systems provides several benefits, including power factor correction, bus voltage regulation, power and energy loss reduction, feeder and system capacity release, and power quality improvement.
The second method is to use the ETAP Optimal Power Flow (OPF) program to optimize the capacitor sizes based on the candidate locations selected by the engineer. This method requires per-selected locations, since OPF can optimize the capacitor sizes but not the locations.
The second stage employs a statistical approach to assess the reduction in energy losses resulting from the capacitors placement in each of the network nodes. Accordingly, the expected beneficiaries from improving the power factor are mainly large inductive networks such as large scale factories and industrial field.
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.
