The system response to accidental islanding and effect on anti-islanding detection of distribution feeders with multiple distributed generation (DG) technologies (synchronous machine and inverterbased units) is one major utility concern associated with increasing penetration of DG. Studies have been conducted to evaluate the performance of anti-islanding detection through use of conventional vo...

Rapid growth in the utilization of inverter-interfaced distributed energy resources (IIDERs) microgrids has brought new challenges network protection area. Microgrid specifically becomes a concern during operation islanded mode. There is considerable reduction fault current levels this mode compared to when microgrid connected grid, which makes conventional algorithms operate with significant d...

This study illustrates the Electrically Assisted power Steering (EAS) using BLDC motor for a vehicle. Earlier the Electrically Assisted power Steering (EAS) was implemented with DSP. This study shows the usage of a dsPIC to control the BLDC motor with an encoder. The BLDC motor here is driven by dsPIC through a three phase inverter system. IRAMS type of inverter is used which is cost efficient ...

the iranian ministry of energy commands the regional electrical companies to install dg resources at 63kv/20kv substations and at the end of 20kv lines. the first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. this paper is aimed to propose an appropriate algorithm for siting and sizing such resources in bakhtar regional el...

restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the distributed generation (dg) resources. dg units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. in this paper, the allocation and sizing of di...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

The microgrid (MG) is a popular concept to handle the high penetration of distributed energy resources, such as renewable and storage systems, into electric grids. However, integration inverter-interfaced generation units (IIDGs) imposes control protection challenges. Fault identification, classification isolation are major concerns with IIDGs-based active MGs where IIDGs reveal arbitrary imped...
