This paper presents a new reliable algorithm of loss of mains detection for distributed generation. One of the technical issues created by DG interconnection is inadvertent islanding. Islanding occurs when a portion of the distributed system becomes electrically isolated from the remainder of the power system, yet continues to be energized by DG connected to the isolated subsystem. It can be de...

The paper presents a study of the impact of increasing amount of distributed generation (DG) on control and management (operation) of transmission and distribution systems. Paper considers how DG penetration influences frequency control during normal and emergency operational conditions. Controllability of different types of DG associated with frequency control is considered. List of power syst...

Distributed Generation (DG) can help in reducing the cost of electricity to the costumer, relieve network congestion and provide environmentally friendly energy close to load centers. Its capacity is also scalable and it provides voltage support at distribution level. Hence, DG placement and penetration level is an important problem for both the utility and DG owner. The cost of electricity as ...

This paper proposes a Particle Swarm Optimization (PSO) based technique for the optimal allocation of Distributed Generation (DG) units in the power systems. In this paper our aim is to decide optimal number, type, size and location of DG units for voltage profile improvement and power loss reduction in distribution network. Two types of DGs are considered and the distribution load flow is used...

The distributed generation (DG) systems based on the renewable energy sources have rapidly developed in recent years. These DG systems are powered by micro sources such as fuel cells, photovoltaic (PV) systems, and batteries. The micro grid concept consists of two stages, in the first stage the low level voltage from the pv cell is converted to high level voltage by using DC-DC converter. In th...

It is now more than a decade since distributed generation (DG) began to excite major interest amongst electric power system planners and perators, energy policy makers and regulators as well as developers. This paper presents an overview of the key issues concerning the integration f distributed generation into electric power systems that are of most interest today. The main drivers behind the ...

The recently observed increase in distributed generation based on renewable energy sources (DG/RES) in the European electricity system is most likely to continue or even increase its growth rate in the future. Distributed Generation (DG) as one core focus of this paper is mainly meant to be connected to distribution grid areas. Thus, scenarios for DG/RES development on distribution level are de...

Power system has dynamic behavior as it faces various disturbances like sudden variation in load, sudden variation in generation and different faults. Due to the variation of load demand, the operation, maintenance and control of power system have become a challenging task. To meet the load requirements, many noticeable research activities are going on in the field of deregulation, restructurin...
