“…It is well known that the implementation of DG connected to the grid in the power system influences the operation of protection system performances [22]. Thus, it is crucial to ensure the proposed fault detection scheme is able to operate correctly even with the presence of DG in the grid.…”

<span>Distance relay is prone to mal-operate during power swing, thus most of modern distance relay design is equipped with power swing blocking scheme to block the operation during power swing and reset the blocking operation whenever a fault occurs during power swing. However, the detection of fault during power swing especially for high resistance fault possess a challenging task, therefore it may cause the unblocking function to vulnerable to operate. This paper presents the development of a detection scheme for detecting fault during power swing in test system interconnected with Distributed Generation (DG). In this study, the detection scheme is proposed based on S-Transform analysis on the distance relay input voltage signal. It is demonstrated that the proposed S-Transform detection based scheme can effectively detect various type of fault during power swing includes high resistance fault, as well as able to operate correctly even with the presence of DG in the test system.</span>

“…To reduce the distribution system losses there are three well known techniques are available; network reconfiguration, optimal capacitor allocation and DG placement. Out of these three techniques DG allocation has both technical as well as economic benefits that have presented in the research paper [7][8][9][10]. Recently many studies have been employed to reduce the system losses by optimal sizing and siting of DG.…”

Due to the restructuring in electricity market and environmental concerns penetration level of DG unit has been increased rapidly. It is also playing a significant role in minimization of line losses of a power system network. So it is very important to define the size and location of distributed generation unit to be allocated in a power system network. On the other hand due to radial distribution systems basic inherent features such as radial structure, a wide range of ⁄ ratios, and a large number of nodes; the optimal sizing and siting problem of a DG unit cannot be determined by the conventional techniques, which are used for transmission systems. A novel method for the estimation as well as minimization of losses in a radial distribution system with DG unit has been presented in this paper. It also improves the voltage profile of the existing power systems and in addition a combined and optimal power factor is also calculated. An algorithm is presented in this paper to obtain the optimum position of DG units in the distribution network based on the available amount of DG using Fuzzy logic. Forward backward sweep method makes the load flow solution faster. Test results on a 33-bus system reveal that the superiority and simplicity of the proposed algorithm.

“…In a typical distribution system, particularly, in developing countries, network losses are as much as 13-20% of total power generated is wasted in the form of power losses [2,3], which would cost millions of dollars every year. Electrical losses (active or reactive) in distribution utilities are generally of two types: technical and non-technical.…”
