Abstract
—This paper presents a new and efficient approach for
capacitor placement in radial distribution systems that determine the
optimal locations and size of capacitor with an objective of
improving the voltage profile and reduction of power loss. The
solution methodology has two parts: in part one the loss sensitivity
factors are used to select the candidate locations for the capacitor
placement and in part two a new algorithm that employs Plant
growth Simulation Algorithm (PGSA) is used to estimate the optimal
size of capacitors at the optimal buses determined in part one. The
main advantage of the proposed method is that it does not require any
external control parameters. The other advantage is that it handles the
objective function and the constraints separately, avoiding the trouble
to determine the barrier factors. The proposed method is applied to 9,
34, and 85-bus radial distribution systems. The solutions obtained by
the proposed method are compared with other methods. The
proposed method has outperformed the other methods in terms of the
quality of solution
