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,in a hybrid thermal-hydro system for finding the required amount of load to be shed for setting the frequencyThe load shedding steps were obtained based on the rate of change of frequency with the increase in the

Short-term prediction of influent flow rate and ammonia concentration in municipal wastewater treatment

Shuai MA, Siyu ZENG, Xin DONG, Jining CHEN, Gustaf OLSSON

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 1,   Pages 128-136 doi: 10.1007/s11783-013-0598-9

Abstract: method is presented in this paper in order to estimate and predict the periodicity of the influent flow rateinfluence of the rainfalls, a linear fitting model is derived to estimate the relationship between flow rateThe results show that 1) for both of the two plants, the periodicity affects the flow rate and NH concentrationsin different cycles (especially cycles longer than 1 day); 2) when the flow rate and NH concentrationsperiodicity influence is larger than rainfalls; 4) the rainfalls will make the periodicity of flow rate

Reduction of wastewater toxicity and change of microbial community in a hydrolysis acidification reactor

Xin Xing, Yin Yu, Hongbo Xi, Guangqing Song, Yajiao Wang, Jiane Zuo, Yuexi Zhou

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 6, doi: 10.1007/s11783-018-1055-6

Abstract:

HAP was verified to reduce the toxicity of TMP wastewater effectively.

Actual TMP wastewater was fed in HAP with different dilution ratios for 240 days.

Formaldehyde, 2-ethylacrolein, TMP and 2-ethylhexanol were all greatly removed.

Firmicutes became the dominant phylum (the abundance increased to 57.08%).

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.
