Recently, there has been great interest in the integration of distributed generation units at the distribution level. The foreseeable large use of DG in the future requires the distribution system engineers to properly take into account its impact in the system planning. When considering DG impact the attention should be paid in the siting and sizing of DG units. This paper proposes the use of ...

The optimal management of distributed generation (DG) enhances the efficiency of the distribution system; On the other hand, increasing the interest of customers in optimizing their consumption improves the performance of DG. This act is called demand side management. In this study, a new method based on the intelligent algorithm is proposed to optimal operate the demand side management in the ...

In this project a Microgrid consisting of different distributed generation (DG) units are presented. These distributed generation (DG) units are connected to the distribution grid. The distributed energy resources are necessary to saving the energy for future use. Here an Energy-management algorithm is implemented to coordinate the operations of the different DG units in the Microgrid for grid-...

Penyambungan pembangkit tersebar (Distributed Generation/DG) ke jaringan distribusi menghadapi beberapa tantangan. Salah satunya terkait dengan skema sistem proteksi. Koordinasi proteksi eksisting tidak mampu bekerja baik tersambungnya DG. Perubahan level arus hubung singkat, aliran daya dua arah, blinding protection, false trip, dan kegagalan auto recloser merupakan permasalahan yang disampaik...

This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...

This paper examines a California-based microgrid’s decision to invest in a distributed generation (DG) unit fuelled by natural gas. While the long-term natural gas generation cost is stochastic, we initially assume that the microgrid may purchase electricity at a fixed retail rate from its utility. Using the real options approach, we find a natural gas generation cost threshold that triggers DG...

This project presents a new methodology using Fuzzy and Harmony Search Algorithm (HSA) for the placement and sizing of distributed generation units in the distribution systems to reduce the power losses and to improve the voltage profile within the limits. Distribution systems are typically spread over large areas and are responsible for a significant portion of total power losses. Electrical e...

Restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the Distributed Generation (DG) resources. DG units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. In this paper, the allocation and sizing of di...
