Load shedding scheme for an interconnected hydro-thermal hybrid system with SMES

D. TYAGI, Ashwani KUMAR, Saurabh CHANANA

Frontiers in Energy 2012, Volume 6, Issue 3,   Pages 227-236 doi: 10.1007/s11708-012-0198-6

Abstract: The frequency of the power system varies based on the load pattern of the consumers.With continuous increase in the load, the frequency of the system keeps decreasing and may reach itsFurther increase in the load will result in more frequency drop leading to the need of load shedding,The load shedding steps were obtained based on the rate of change of frequency with the increase in theload in both areas.

Climate change and China’s mega urban regions

Chaolin GU, Sunsheng HAN

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 4,   Pages 418-430 doi: 10.1007/s11709-010-0075-5

Abstract: China’s mega urban regions are focal points of economic development and environmental concerns. This paper positions four mega urban regions (i.e., the Yangtze River Delta, the Pearl River Delta, the Bohai Bay Area, and the South-eastern Fujian Province) along China’s coast into the national economy and elaborates their development challenges and planning innovations. Mega urban regions in China are spatial consequences of rapid economic transition. They deserve close scrutiny and demands for innovative planning responses in order to maintain their key role in driving economic growth but limiting their greenhouse gas emission.
