Nirdeshak is developing tailor made comprehension section from the recent news articles published in leading newpapers across the world. It is important to recognizing letters and words in the passage, as it is the first step in learning to read. For students it is vital that students comprehend, or understand, what they are reading. They must be able to get the meaning of the text: What is the author telling the reader?
Deploying solar power at the scale needed to alleviate climate change will pose serious challenges for today’s electric power system, finds a study performed by researchers at MIT and the Institute for Research and Technology (ITT) at Comillas University in Spain. For example, local power networks will need to handle both incoming and outgoing flows of electricity. Rapid changes in photovoltaic (PV) output as the sun comes and goes will require running expensive power plants that can respond quickly to changes in demand. Costs will rise, yet market prices paid to owners of PV systems will decline as more PV systems come online, rendering more PV investment unprofitable at market prices. The study concludes that ensuring an economic, reliable, and climate-friendly power system in the future will require strengthening existing equipment, modifying regulations and pricing, and developing critical technologies, including low-cost, large-scale energy storage devices that can smooth out delivery of PV-generated electricity.
Most experts agree that solar power must be a critical component of any long-term plan to address climate change. By 2050, a major fraction of the world’s power should come from solar sources. However, analyses performed as part of the MIT “Future of Solar Energy” report found that getting there won’t be straightforward. “One of the big messages of the solar study is that the power system has to get ready for very high levels of solar PV generation,” says Ignacio Pérez-Arriaga, a visiting professor at the MIT Sloan School of Management from IIT-Comillas.
Without the ability to store energy, all solar (and wind) power devices are intermittent sources of electricity. When the sun is shining, electricity produced by PVs flows into the power system, and other power plants can be turned down or off because their generation isn’t needed. When the sunshine goes away, those other plants must come back online to meet demand. That scenario poses two problems. First, PVs send electricity into a system that was designed to deliver it, not receive it. And second, their behavior requires other power plants to operate in ways that may be difficult or even impossible.
The result is that solar PVs can have profound, sometimes unexpected impacts on operations, future investments, costs, and prices on both distribution systems—the local networks that deliver electricity to consumers—and bulk power systems, the large interconnected systems made up of generation and transmission facilities. And those impacts grow as the solar presence increases.
To examine impacts on distribution networks, the researchers used the Reference Network Model (RNM), which was developed at IIT-Comillas and simulates the design and operation of distribution networks that transfer electricity from high-voltage transmission systems to all final consumers. Using the RNM, the researchers built—via simulation—several prototype networks and then ran multiple simulations based on different assumptions, including varying amounts of PV generation.
The Swedish newspaper was recently asked it to delete the reference made by President Pranab Mukherjee to the Bofors scam in an interview to it, as a claim protested by the Indian Government on 27 May 2015. India has expressed disappointment over the disrespect shown to the President, the newspaper has defended its right to publish what was said during the interview.
Know, who is Vijay Kelkar and what is PPP !
Vijay Kelkar is a renowned economist and a former Finance Secretary. He was appointed head of newly constituted committee to give recommendations to recast the model of Public-Private-Partnership (PPP) model in India. India is one of the largest PPP market with over 900 projects. The Kelkar committee will review the PPP policy, suggest a better risk-sharing mechanism between private developers and the government after analysing such projects.
Know, who is Yaduveer Krishnadatta Chamaraja Wadiyar !
Yaduveer Krishnadatta Chamaraja Wadiyar was crowned as the new Maharaja of of Mysuru (Mysore) royal family. He is the 23-year old grandson of Princess Gayathri Devi, who was the eldest daughter of the last Maharaja of Mysore, Sri Jayachamarajendra Wadiyar. The coronation was held at Mysuru’s famous Amba Vilas Palace, which was decked up for the occasion.
Know about Sepp Blatter!
Swpp Blatter, was re-elected as FIFA president for a fifth term at the 65th Annual Congress of FIFA held at Zurich for four year term.
Prince Ali bin al-Hussein of Jordan stood against Blatter in this election. It is worth mentioning that FIFA is going through a major controversy regarding corruption in the organisation with two FIFA vice presidents and a recently elected FIFA executive committee member still in custody.
