Distributed Generation (DG) is a promising solution to many power system problems such as voltage regulation, power loss, etc. This paper presents a new methodology using a new population based meta heuristic approach namely Artificial Bee Colony algorithm(ABC) for the placement of Distributed Generators(DG) in the radial distribution systems to reduce the real power losses and to improve the v...
For the last three decades, a large scale integration of distributed generation (DG) is beginning to change the electrical distribution network from passive to active. Consequently, technical difficulties are created by significant impacts generated by DGs with voltage variation being the dominant effect. This paper presents a comprehensive review of voltage control techniques on electrical dis...
Department of Mathematics Sathyabama University, Chennai – 119 [email protected] Abstract This paper deals with the Distributed Generation (DG) capacity of the electrical power system. DG capacity is formulated as a Mixed Integer Programming (MIP) problem with respect to various operating constraints in power generation. The objective of this model is to minimize the real power loss by ...
Penetration of distributed generation in the power grid is increasing. This situation leads to new possibilities but also new issues, such as anti-islanding protection. During a loss-of-mains or islanding situation, distributed generation (DG) units remain feeding a part of the electrical network without connection to the main power system. Currently, DG units have to be disconnected from the g...
attention in recent times due to constraints associated with conventional power generation and new advancements in DG technologies .The need to operate the power system economically and with optimum levels of reliability has further led to an increase in interest in Distributed Generation. However it is important to place Distributed Generator on an optimum location so that the purpose of loss ...
Distribution networks reconfiguration, capacitor placement and distributed generation resources placement are three methods of loss reduction, used in many studies. Individual optimization, without considering their mutual effect, result in suboptimal answer in these works. In this paper, a new method is presented for simultaneous optimization of place and size of DG and capacitors as well as t...
In this paper, a method is proposed for accurate sharing of harmonic and unbalanced loads in islanded microgrids. The proposed method can adaptively improve the load sharing among distributed generation (DG) units based on the circulating currents rules and harmonic and unbalanced powers provided by each DG. Compared with previous methods, the proposed method does not require a dedicated centra...
In this paper, a new control strategy for control of a distributed generation (DG) unit in islanding mode is proposed using the particle swarm optimization (PSO) technique. The potential of the proposed approach for optimal setting of the conventional lead-lag controller has been investigated. When connected to the utility grid, the DG is controlled by interface voltage source converter (VSC) w...
due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...
