This paper proposes a methodology for practical siting and sizing of Hybrid energy systems (HESs) consist of: wind turbine (WT), photovoltaic (PV) and combined heat and power (CHP) units. In this method, the interaction of Plug-in Electric Vehicles (PIEVs) in the electric distribution system is considered. Electric Vehicle are seen to have some negative impacts on electric distribution system p...
Electric distribution companies regulation has important effect on power system. Distribution services costing are done by two method, price base and performance base. Distribution company cost include operational and investment. Services quality, productivity improvement and etc are applied by benchmarking. With regard to different condition of companies, it is important that regulator benchma...
generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. a failure of component is resulted from failing in the operation or overloading. in addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. thus, tolerable repair times may be overl...
The electric industry has gone through dramatic changes over the past two decades. The restructuring program begun in the early 1990s opened up the wholesale markets with numerous competitive generation companies transacting over open-access transmission systems. New entities called independent system operators (ISOs) and regional transmission organizations (RTOs) arose as wholesale market oper...
in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...
Introduction of new technologies such as energy storage systems, electric vehicles, and distributed generation improved the characteristics of networks. On other hand, using these components in distribution systems improves system performances such as power losses. One of effective methods for improving system characteristics is distribution network reconfiguration. In this study, in addition t...
Power system restructuring has increased the take part distribution side of power system in providing power. Extensive influence of distribution resources for generation power in distribution side of power system and transferring power electricity between retailer and household consumers are the reason of that. Among different types of distributed resources, micro combined heat and ...
Generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. A failure of component is resulted from failing in the operation or overloading. In addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. Thus, tolerable repair times may be overl...
by developing the level of life in societies, the need for new resources of energy becomes more important. in almost all cases, the aim is to convert one form of energy to the electrical form. with advances of technology and use of new electric and electronic devices and gadgets, the need for electrical energy is increasing and providing stable and continuous electric power becomes very importa...
