The increasing amount of distributed generation in public networks sets new requirements for the traditional network protection schemes. Actual problems have been experienced relating for instance to fault levels, reclosings and earth faults. As the complex protection is often considered a barrier against more wide-scale use of distributed energy resources, new development is needed. New genera...

DC/DC boost converters are usually used to interface the DC output of modern distributed generation resources with the AC system. Distributed generation modules are aggregated to yield the necessary power using either parallel or cascaded architecture. Detailed modeling of an interconnection system incorporating cascaded architecture has not been considered in previous researches. In this paper...

This paper presents a multi-objective formulation for optimal siting and sizing of distributed generation (DG) resources in distribution systems in order to minimize the cost of power losses and energy not supplied. The implemented technique is based on particle swarm optimization (PSO) and weight method that employed to obtain the best compromise between these costs. Simulation results on 33-b...

in this paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...

renewable energy sources (res), especially wind power plants, have high priority of promotion in the energy policies worldwide. an increasing share of res and distributed generation (dg), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

Greater penetration of Distributed Energy Resources (DERs) in power networks requires coordination strategies that allow for self-adjustment of contributions in a network of DERs, owing to variability in generation and demand. In this article, a distributed scheme is proposed that enables a DER in a network to arrive at viable power reference commands that satisfies the DERs local constraints o...

Microgrid and smart electrical grids are among the new concepts in power systems that support new technologies within themselves. Electric cars are some advanced technologies that their optimized use can increase grid efficiency. The modern electric cars sometimes, through the necessary infrastructure and proper management, can serve as an energy source to supply grid loads. This study was cond...

Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...

This work develops a distributed fast-frequency control framework for application in self-consuming energy communities. We propose consensus optimization of inertia coefficients based on the individual resource constraints grid-friendly resources (ders), which relies presence peer-to-peer communication infrastructure. In proposed strategy, ders are optimally tuned real-time by faster loop to im...
