Using both ceramic and electrolytic output capacitors, in parallel, minimizes capacitor impedance across frequency. The losses in these types of capacitors will be studied. HF Ceramic Capacitor The power losses in a capacitor is calculated as follows.
In [111, 112], a two-stage method was used to solve the optimal capacitor placement problem. First, the power loss index (PLI) in and the LSFs in were utilized to determine the high potential buses for capacitor placement.
In , an improved whale optimization (IWO) algorithm has been used to solve the problems of capacitor allocation in a distribution system.
In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
It is clear that the line active and reactive power flows based on fixed and switched capacitors are lower than those obtained in the case of without capacitors. In addition, the directions of reactive power flows are reversed in nine lines for fixed capacitors and in seven lines for switched capacitors.
