(11 posts)Its a load study nothing more. Power every now and then is not a viable option. Blackouts of the grid are the major requirement of design by FERC, NERC and DOE. If you do not mind power outages on a large scale every now and then this approach is great. I would also look at the author and where the paper was published. If the paper were a seminole work you would expect PSERC or IEEE as the published forum. The paper was rejected by the IEEE as nothing new. There have been many papers presented on this subject with the same or similar scope. The paper does not provide necessary information on numerical or simulation method required by pier review in the power standards industry.
The only available alternative to fossil or nuclear for grid stability is energy storage. Large amounts of energy storage and the ability to deliver (transmission lines) will be needed to consider the premise anything other than a theoretical exercise. Currently practical attempts to achieve what was presented in the paper have created major blackouts. ERCOT outage and the Spanish grid in 2009 are great examples. This paper is not a reference I would use since the scope does not provide the means need to achieve large integration only load matching.
I will give you a few sources that will illustrate the problems but system studies engineer in the industry learned understand what I am telling you from a formal education in Power Engineering. I have added a listing from a great text a book on power systems stability that has a great section on problems with current renewable controllers. I work with Solomon Yerga who was Kundor's grad student and put most of the book together. The good news is a lot of work is being performed in large scale renewable integration and the out look is doable if a new contolers and a transitional strategy can be worked out. My belief is grid storage on a large scale is a possible bridge. The control and protection systems currently sold simply can not keep the lights on as needed by our modern society.
