To reflect the bilateral transaction's uncertain impact on the grid, the effective reserve and the reserve channel margin are defined. And reserve capacity is modeled based on stochastic simulation and bi-level programming considering the congestion risk, which the reserve services are regarded as object of study in the open power market environment. The upper optimization level is to maximize the...
After discussing the complexity of activated sludge system, its biological mechanism, and characteristics of traditional activated sludge method, the paper established a cellular automata model for traditional activated sludge processes, and then made simulations with practical parameters. The results indicate that the model well represents the evolvement of microbe in one upright section through...
The decarburization predication model was used to detection of carbon content in RH degasser. Decarburization predication system in RH degasser uses computer technology to analyze on-line data, to study the relation between the carbon content and the difference type molten steel data and processing data and to recognize carbon content of the steel with expert knowledge. The recognizing results can...
With the development of electricity market fair competition becomes the most important and basic principle. Although the transmission losses account for a very small part in the full cost of the electric transactions, how to allocate the transmission losses has great effects on the special trade and the network customers. The paper proposes the analytic expression of power components distributing...
Based on the simulation experiment and hydrological data of water quality of Yangshapao Lake in the Project Diversion from Nenjiang River to Baicheng City, the transport model of water quality and hydrodynamic model of Yangshapao Lake are built. DELFT3D Software is adopted to simulate the fluorine in the water according to three different schemes, such as existing reservoir capacity, dead reservoir...
Considering the complexity and abundant kinetics behaviors of activated sludge, the paper established a cellular automata model (CAM) for adsorption and biodegradation in activated sludge process. The simulations with practical parameters were made. The results indicate that the CAM replicates complex adsorption and biodegradtion, and well describes the removal of biochemical oxygen demand (BOD) and...
Net ecosystem exchange (NEE) is a critical ecological parameter indicating the exchange of carbon dioxide between vegetation and atmosphere, which is widely used in the field of carbon cycle researches. It is common measurement by flux tower based on eddy covariance technique can only represent local status, however regional NEE is much more important. This paper introduces a spatialization method...
