The fog computing paradigm emerged as a promising solution to realize deployment of large-scale Internet Things (IoT) environments and low latency real-time services. It leverages large number resource-constrained, heterogeneous compute nodes distributed across vast geographical areas located closer users data sources, compared the cloud which is usually at centers, far from IoT devices. In an ...

This project presents a new methodology using Fuzzy and Harmony Search Algorithm (HSA) for the placement and sizing of distributed generation units in the distribution systems to reduce the power losses and to improve the voltage profile within the limits. Distribution systems are typically spread over large areas and are responsible for a significant portion of total power losses. Electrical e...

Generally during recent decades due to development of power systems, the methods for delivering electrical energy to consumers, and because of voltage variations is a very important problem ,the power plants follow this criteria. The good solution for improving transfer and distribution of electrical power the majority of consumers prefer to use energy near the loads .So small units that are co...

Presence of distributed energy resources (DERs) in the case of proper planning can help to improve the technical and economic parameters of the system in distribution networks. In recent years, several algorithms and indices for optimal distributed generation planning with multiple objectives have been presented. In this paper, optimal placement and sizing of distributed generation sources with...

Placement of protection devices in a conventional feeder (without distributed generation) is often performed so as to minimize traditional reliability indices (SAIDI, SAIFI, MAIFIe...), assuming the sole source(s) of energy at substation(s). Distributed generation (DG) and storage units located on the feeder may be constrained in terms of power and/or energy capacity, and may include renewable ...

Wind Power Distributed Generators (WPDGs) are being increasingly placed in the power system due to their several technical and environmental benefits. In this paper, a Modified Particle Swarm Optimizer (MPSO) based method is proposed for placement of multiple WPDGs and capacitors. Monte Carlo Simulation (MCS) based probabilistic load flow, considering uncertainty in load demand and wind generat...

Smart Grids are result of utilizing novel technologies such as distributed energy resources, and communication technologies in power system to compensate some of its defects. Various power resources provide some benefits for operation domain however, power system operator should use a powerful methodology to manage them. Renewable resources and load add uncertainty to the problem. So, independe...

the operation of a distribution system in the presence of distributed generation systems has someadvantages and challenges. optimal sizing and siting of dg systems has economic, technical, andenvironmental benefits in distribution systems. improper selection of dg systems can reduce theseadvantages or even result in deterioration in the normal operation of the distribution system. dgallocation ...

in restructured power systems and in a wholesale power market, a distribution company as a market player intends to maximize its profit by utilizing its options. hence determining an optimal energy acquisition strategy for a distribution company is vital, for attaining to this goal. however an important challenge for determining these strategies is forecasting other competitors and generation c...
