China plans super-grid for clean power in Asia

Financial times

As hydropower hits problems, China plans renewable energy for region

The Belt and Road Initiative (BRI), China’s ambitious outbound investment strategy which links at least 65 countries along terrestrial and maritime trade corridors, will open massive new opportunities for trade and investment in frontier markets. Energy infrastructure investments are a backbone of BRI, so aligning these investments with sustainable development goals is necessary for China to navigate regional patchworks of social, environmental and economic priorities.

The History of Electrification

The power grid started with long distance transmission and soon led to interconnected systems, these are some of the landmark early power generation sites.

The power grid as we know it began with isolated power generation systems across the world starting in the 1870s. The growth and unification of the systems into an interconnected AC power ‘grid’ helped raise the quality of life of people from all classes.

Direct Current Beginnings:

DC power systems dominated in the 1870’s and 1880s. “Small” systems were sold to factories around the world, both in urban areas, and remote undeveloped areas for industrial/mining use. Thomas Edison, Charles Brush, and Werner von Siemenslead the industry in DC systems. DC systems powered factories and small downtown areas but did not reach 95% of residents. Electric lighting was a luxury found only in hotels and other businesses as well as in the mansions of people like George Westinghouse and J.P. Morgan. Tiếp tục đọc “The History of Electrification”

Harmonizing the Benefits of Distributed Energy Resources for the Benefit of the Grid

We need to set the right framework for DER integration, argues Stephanie Wang.

by Stephanie Wang, November 13, 2015

greentechmedia – California is rethinking how to incentivize consumers to manage their energy use. In September, the California Public Utilities Commission (CPUC) said it would seek to create an integration framework to make choosing and integrating distributed energy resources easier for consumers.

The CPUC found that “harmonization” of consumer benefits and “system” (grid and societal) benefits is necessary for integrating more distributed energy resources (DERs). How can we harmonize these benefits with simple, scalable solutions that work for consumers and communities?
Equalize or align benefits

Let’s start with a fundamental question on the definition of harmonization. Does that mean equalization of benefits — ensuring that benefits to consumers and the system are roughly equal? Tiếp tục đọc “Harmonizing the Benefits of Distributed Energy Resources for the Benefit of the Grid”
