N2 - The selection of placement and size for the multiple distributed generations (DGs) based on renewable energies becomes an important issue to operate modern power systems safely and reliably. This paper extends the previous study in [1] by treating the problems for their optimal locations and sizes in more realistic way based on the power loss sensitivities and Kalman filter algorithm, respectively. In particular, the proposed method is implemented by the simulation on a part of practical distribution network of 60 MVA-scale, which is located at the Do-gok area in Seoul, Korea. The new factor, called as the optimal locator index (OLI), is developed to determine the optimal locations in a systematic and effective manner by the power loss sensitivities. Also, the Kalman filter algorithm is applied to determine the optimal sizes by choosing the step size of 10 KW, which is much smaller increment than the 10 MW step used in [1], without requiring high computational efforts. This selected step size of 10 KW is realistic and suitable to apply it for the practical test system.
