Vibration profile comparison of grid connected and battery-grid connected transformers

2021 IEEE PES Innovative Smart Grid Technologies - Asia (ISGT Asia), 2021
This paper presents a comparison of vibro-acoustic data from two different three-phase transformers, a traditional grid connected transformer and one used to connect a 1.1 MW battery to the grid. The influence of harmonics on transformer vibration, is well documented and of serious concern. Typically, transformers within standard grid connected systems

A Virtual Connectivity Layer for Grids

2009 Fifth IEEE International Conference on e-Science, 2009
Computational grids are now mainstream facilities for e-research worldwide. While enterprise grids exist within organizations, national grids have become common, usually consisting of government as well as academic facilities. Such facilities are not uncommonly lenient with blanket policies to allow inbound and outbound grid traffic.

Series-Connected Adaptive Stabilizer for the Grid Connected Inverter at Weak Grid

2018 Asian Conference on Energy, Power and Transportation Electrification (ACEPT), 2018
This paper proposes a series-connected adaptive stabilizer (SAS) to fix the instability problem between the grid-connected inverter (GCI) and the weak grid via shaping the grid impedance. Different from the traditional stabilization method, the SAS does not need to know the information about the GCI, therefore, it can be treated as a module ...

Glogin - Interactive Connectivity for the Grid

2005
Todays computational grids are used mostly for batch processing and throughput computing, where jobs are submitted to a queue, processed, and finally delivered for post-mortem analysis. The glogin tool provides a novel approach for grid applications, where interactive connections are required.

Optimal sizing of a grid-connected microgrid

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
In this paper, we propose a novel method to determine the optimal sizing of a grid-connected Microgrid which includes Photovoltaic (PV) system, battery energy storage system (BESS). The problem is viewed as a constrained optimization. In particular, the objectives are to minimize the annual cost of the system (ACS) with zero unmet loads as well as to ...

Grid connection of renewable energy

2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010
The paper will consider various techniques that have been used to help renewable generation connect to the grid. The first is the use of STATCOM technology for the supply of voltage and power factor control by supplying fast var's to meet the reactive requirements of the grid code and also to support installations which are connecting to a weak grid ...
