Increasing power consumption threatens system stability and causes losses, so distributed generation is considered a cost‑effective alternative whose benefits depend on location and size, yet systematic guidelines for optimal placement remain unclear. The study aims to identify the optimal locations and sizes of distributed generators to preserve stability and reliability before grid connection. The authors propose a loss‑based method to locate multiple DGs and use a Kalman filter algorithm to compute their optimal sizes.
Increase in power consumption can cause serious stability problems in electric power systems if there are no ongoing or impending construction projects of new power plants or transmission lines. Additionally, such increase can result in large power losses of the system. In costly and environmentally effective manner to avoid constructing the new infrastructures such as power plants, transmission lines, etc., the distributed generation (DG) has been paid great attention so far as a potential solution for these problems. The beneficial effects of DG mainly depend on its location and size. Therefore, selection of optimal location and size of the DG is a necessary process to maintain the stability and reliability of existing system effectively before it is connected to a power grid. However, the systematic and cardinal rule for this issue is still an open question. In this paper, a method to determine the optimal locations of multiple DGs is proposed by considering power loss. Also, their optimal sizes are determined by using the Kalman filter algorithm.
