Worldwide demand for energy continues to grow each year, while at the same time, concerns about climate change are leading to stricter emissions regulations. Renewable energy sources and distributed generation will play an increasing role in current and future electric power systems. In this research an attempt is made to use the Genetic Algorithm based optimization method to calculate the percentage...
The structure of power system is changing around the world. With the increase in size and complexity of the distribution network, it is important to automate the system for proper monitoring and control. Service restoration is one of the techniques used by utilities to supply the power to healthy part of the network which gets isolated after occurrence of fault. The restoration plans have changed...
In the recent past factors such as apprehensions over impacts of environmental aspects, distribution network improvement conditions, and other subsidised programs of the government have affected the distributed generators (DG) units count in commercial and domestic electrical power output. It is known that the optimal size and optimal placement of DG units may lead to low power losses, high voltage...
Distributed power generation is a small-scale power generation technology that provides electric power at a site closer to customers than the central generating stations. The Distributed Generation (DG) has been created a challenge and an opportunity for developing various novel technologies in power generation. The proposed work discusses the primary factors that have lead to an increasing interest...
Based on the improved genetic algorithm, a wind biomass co-generation system (WBCS) planning model is put forward. The expansion plan which minimize the total cost is introduced to increase the reliability of Micro-Grid(MG) and meet the nonlinear constraints of system planning and operation. In the process of planning the total cost, not only the unit construction cost and operation cost are considered,...
Great changes will happen to the distribution network structure with the distributed generation(DG) connected into the network, and the power flow and short-circuit current in distribution network will also change correspondingly. All of these have effects on the normal operation of relay protection device in distribution network. The more DGs are connected into the network, the greater influence...
With the introduction of restructuring concepts to traditional power systems, a great deal of attention is given to the utilization of distributed generation. Since the integration of DG units has been known as an alternative for main grid as a resource for energy supply, the determination of optimal sizing and sitting is an important issue in the planning procedure of DG. This work presents a comprehensive...
With the increasing share of distributed generation in electrical energy supply, the proper planning procedure for using these units, has become more vital for power system planners. In this paper, the application of multi-objective optimization techniques for siting, sizing and determination of the proper technology to be used, has been investigated in such a way that, the load demand during the...
With increasingly proportion of distributed generation (DG) in the power system, traditional power system planning has new challenges and demands. The necessity for flexible electric system, changing regulatory, energy savings and environmental impact are providing impetus to the development of DG. Itpsilas critical that the power system impacts be assessed accurately so that DG can be applied in...
