The design and prototype of RUDA, a distributed grid accounting system
The grid environment contains a large and growing number of widely distributed sites with heterogeneous resources. It is a great challenge to dynamically manage and account for usage data of grid resources, such as computational, network, and storage resources. A distributed Resource Usage Data management and Accounting (RUDA) system is designed to perform accounting in the grid environment. RUDA ...

Net Meter vs Gross Meter In India
The Indian government had an initial target of 20 GW capacity for 2022, which was achieved four years ahead of schedule. In 2015 the target was raised to 100 GW of solar capacity (including 40 GW from rooftop solar) by 2022. The ambitious target has brought along with it the need to review the existing energy policies in order to satisfy all the stakeholders like prosumers, DISCOMs, energy ...

Context–independent centrality measures underestimate the vulnerability of power grids
Power grids vulnerability is a key issue in society. A component failure may trigger cascades of failures across the grid and lead to a large blackout. Within complex network analysis, structural vulnerabilities of power grids have been studied mostly using purely topological approaches, which assumes that flow of power is dictated by shortest paths. However, this fails to capture the real flow ...

GENCOs multiperiod expansion model in a competitive electricity market
Over the past two decades, several countries have restructured their electricity industry by significantly reducing the government's role in the ownership and management of energy sector. The generation sector was the first activity of the vertically integrated industry to be open for the competition and therefore, it presents the highest level of competitiveness and experience. In the new ...

Simulation-based evaluation of tidal current power output characteristics
Tidal current is considered to be one of the promising alternative green energy resources. This paper introduces a simulation based methodology to evaluate tidal current power output characteristics, including capacity factor, and power production variability patterns. Power variability analysis is crucial to grid integration systems design. The proposed methodology is applied to the well known ...

Off Grid Solar Power Systems Design:The Beginner’s Guide in 2018
The off-grid solar system is an array of solar power components meant to run daily operations of electrical devices in absence of electricity. A similar array of solar power is the use of grid-tie solar systems; systems that are required to run electric appliances whenever utility grid is not supplying power. The grid-tie system is connected to the utility power source and works interchangeably ...

How to Live Off the Grid?
1.Introduction Living off the grid brings memories of a cabin deep in the woods or a hut in the mountains. But in essence, off grid solar system is basically home solar systems providing electricity to private premises and not necessarily in connection with the public grid. Living off the grid is a state of autonomy. It is a way to avoid all the complications that come with sharing electricity ...
