Energy in Transition
Solving the energy trilemma
The second key aspect of hybrid grids: The mix of transmission and distribution (T&D)
This is the third blog I've written in a on series hybrid grids. In my first blog, I defined hybrid grids and introduced their four key aspects: mix of generation, mix of transmission and distribution (T&D), mix of delivery and mix of control. Th ...
VW scandal shows need for independent testing: so let’s work together on it
The recent Volkswagen scandal has highlighted the dire need for third party testing. Without the valuable work done by the California Air Regulations Board and the US Environmental Protection Agency, the faulty test reports may have never been uncove ...
What drives interconnection capacity building between (Regional) Transmission Operators?
The future power system must become more robust to handle the shift from thermal to renewable generation. Controllable fossil-fuel generation (i.e., gas, coal, and to some extent nuclear) are expected to be decommissioned and replaced by less control ...
What effect will new technologies and renewable integration have on the future transmission network?
I had the opportunity to attend DNV GL's 2015 Utility of the Future Leadership Forum last week, and it provided some unique perspective on the state of the industry. Solar energy and storage were topics that were brought up in multiple discussions, ...
Integration of renewable energy sources: Strong challenge for a weak grid
Integration of renewable energy sources whether into transmission or distribution level focuses on incorporation of such sources in a reliable and economic fashion in the bulk electric power system while maintaining the grid integrity, reliability an ...
The continued rise of the prosumer: Three customer-centered solutions to impacts of distributed energy resources
Distributed Energy Resources (DER) constitute a rapidly expanding sector in the US, particularly in the west, resulting in a new class of utility customer who produces as well as consumes energy--the "Prosumer." Some utilities have been forced by pub ...
Power system verification: Component testing is not enough anymore!
Society has become highly dependent on a reliable electric energy supply, due to increasing networking and electronic information exchange developments, and this dependency will only continue to increase causing a double risk trend. In fact, last yea ...
Could Africa be the global star in solar power?
This author no longer works for DNV GL. The trade press has recently reported a number of large (> 50 MWp) renewable energy projects in Africa. As a company at the forefront of Africa's energy transition, we at DNV GL are excited to see so many ...
Will Wireless Power Technology become a key technology in future power distribution?
As a fan of science fiction I watched the movie "Interstellar" a few weeks ago and I loved it. It was that movie, as well as the (inductive) wireless power charger that my son recently bought for his smart phone, which triggered me to write a blog to ...
2014: The year of the energy storage RFO
On December 16, 2010, the CPUC opened Rulemaking R. 10-12-0 07, with the aim to determine appropriate targets--for each regulated California load-serving entity to procure technically feasible and financially cost-effective energy storage systems--al ...
