This paper presents a new and efficient approach for capacitor placement in
radial distribution systems (RDS) 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 (LSF) are
used to select the candidate locations for the capacitor placement and in part two a new
algorithm that employs Dijkstra Algorithm (DA) 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. The
proposed method is applied to 33 & 69 RDS. 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.
