This paper develops an iterative searching method to find the optimal power management strategy and component sizes for a hybrid power system that consists of a proton exchange membrane fuel cell, a chemical hydrogen production system, photovoltaic arrays, and a Li-Fe secondary battery set. In order to find the most suitable power management and component sizes, we build a MATLAB/SimPowerSystem simulation...
With high penetration of renewable generation, power system operations need additional ramping capability to follow the change of renewable generation. However, without proper unit commitment in the forward energy scheduling process, the system may not have sufficient ramping capability in the real time operation when renewable generation varies while system load is sharply pulling up or ramping down...
The AnnAGNPS model (Annualized Non-Point Source Pollution Model) is applied to analyze the spatial and temporal heterogeneity of agricultural non-point source pollutant loading in Zhangxi Watershed. The spatial database and attribute database of non-point source pollution is then established. Our result shows that in spatial scale, absorbed nitrogen has great spatial heterogeneity, while dissolved...
