The large-scale wind power development in China has reached a bottleneck of grid integrating capability. As a result, excess wind electricity has to be rejected in the nighttime low demand hours, when the wind power is ramping up. To compensate for the fluctuation of wind power, new coal-fired...

As China starts to build 6 10-GW wind zones in 5 provinces by 2020, accommodating the wind electricity generated from these large wind zones will be a great challenge for the regional grids. Inadequate wind observing data hinders profiling the wind power fluctuations at the regional grid level....

In accordance with the economic data from Statistical Communique on National Economy and Social Development in Hubei Province in the period 1980 2009, we use co-integration analysis method to research the impact of GDP growth on residents' consumer spending. Result shows that although there are...

The effect of choosing a non-standard operating frequency on the equipment and infrastructure costs of an offshore AC network is investigated. The offshore AC network considered is similar in design to the European SuperGrid “SuperNode”. It is designed to connect several large wind arrays to...

Solid solution materials show promising performance for applications in rechargeable lithium-ion batteries, but their synthesis and conversion mechanism are still quite a difficult task that needs to be tackled. Herein, a cubic Mn 0.6 Fe 0.4 S solid solution based on conversion reactions is...

In the US, Cohen and Frazzini (2008) shows that suppliers returns are predictable using lagged customers returns. The converse does not hold. In China, however, both predictive directions hold: customer returns predict future sup-pliers’ returns as in the US, and suppliers returns predict...
