Shunt capacitors installation in distribution systems requires optimal placement and sizing. More harmonics are being injected into distribution systems. Adding shunt capacitors may lead to high distortion levels. The capacitor placement and sizing problem is a nonlinear integer optimization problem, with locations and ratings of shunt capacitors being discrete values. The goal is to minimize t...

The inevitable electrothermal coupling among capacitors in a bank will lead to nonnegligible errors the temperature as well lifetime prediction of individual capacitor. In this article, analytical thermal models with corresponding design for capacitor banks are proposed considering effect. First, measurement-based lump model and physical-model-based proposed. Then, help models, method matching ...

This paper uses an effective method, CODEQ method, with integer programming for solving the capacitor placement problems in distribution systems. Different from the original differential evolution (DE), the concepts of chaotic search, opposition-based learning, and quantum mechanics are used in the CODEQ method to overcome the drawback of selection of the crossover factor and scaling factor use...
