During the last years utilities have been facing a strong trend towards new technologies and standards. The most significant task is to fundamentally transform the capabilities and bring new solutions that support better power quality supply. Standardization solution IEC 61850 in terms of protection, monitoring and control functions is a promising solution that provides a great impact on substa...

Paper describes the theoretical and practical aspects of the proposed model that uses distributed computing to a global network of Internet communication. Distributed computing are widely used in modern solutions such as research, where the requirement is very high processing power, which can not be placed in one centralized point. The presented solution is based on open technologies and comput...

The paper highlights on a new method to solve the network reconfiguration problem. The uncertainty of system loads vary from time to time and makes the distribution system operation and control more complex. Thus for a feeder system power loss is not at its minimum. In this context a methodology to reconfigure the microgrid and also to facilitate its operation in autonomous mode is being discus...

This paper presents a new intelligent control strategy for DC microgrid in islanded operation mode based on droop control method. The DC microgrid under study included a Wind Turbine Generator (WTG), photovoltaic (PV), battery energy storage system (BESS) and a linear resistive load. According to the proposed method, each of distributed generation (DG) sources and BESS can be deployed independe...

Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

Recent developments in the electric power and problems arising from construction and maintenance of large power plants have raised a great deal of interest in distributed power generation (DG). Distributed generation units due to specifications, technology and location network connectivity can improve system and load point reliability indices. In this paper, the placement and sizing of Distribu...

Different energy infrastructures, such as electricity, natural gas and local district heating systems utilized for the energy supply are most often planned and operated independently of each other. This paper addresses the optimization of combined electricity and natural gas networks. The couplings between the two energy infrastructures are taken into account with the novel concept of energy hu...

In this paper, attacks caused in the shut circle control system is discussed. To keep the net-worked control systems safe, good, ready and hard to move, getting NCS from of the net attacks is very important. The marked power of thought attackers will not move after any made suggestion copies made to scale, they keep on changing their attack designs as if by chance and dynamically. Distributed g...

This paper is concentrated mainly to the cause and to clear the Power Swings in synchronous generator due to rotor speed oscillations in wind farm which is a distributed generation to maintain the stability of rotor oscillations. The paper presents different conditions of disturbances and faults in specified time period. In Power System Damping Oscillation modes are excited due to disturbance i...
