Smart Grid - The Internet for the Energy Economy

The nation's century-old energy grid might get an upgrade soon to handle alternative energy. The economic stimulus package has earmarked $11 billion to invest in smart meters and 3,000 miles of renewable-energy transmission lines. Venture capitalists and utilities also are investing in smart-grid applications at a record pace. "It's like the Internet for the energy economy," said Katherine Hamilton, head of the GridWise Alliance.

Dynapower - MAXIMIZE PRODUCTION AND REVENUES WITH SOLAR PLUS STORAGE

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
