For example, the China renewable energy industry development report 2018 [61], which assessed the potential of centralized large-scale PV power plants, found only 5% of the area of one land use type, Gobi, to be developed. However, the suitability of other geographical and resource environment conditions was not considered.
The centralized generation has also lower flexibility to failures, than the distributed one. As if a relevant fault occurs in the plant, a big portion of the generation power could be turned off, with relevant impacts in the dispatching and with possible power interruptions for several final users. An Overview of Distributed Vs.
