With the purpose of researching on the influence of CO2 injection tubing with corrosion defects to the safety production of CO2-EOR flooding, experimental tests and finite element simulations were conducted to analyze the failure pressure and stress distribution of P110 pipe with single point corrosion, axial line corrosion and uniform corrosion defects. Metallographic examination was also done to...
The paper introduces multi-agent system (MAS) for intelligent scheduling model of multi-MG autonomy-cooperative operation. Firstly, wind power plants (WPPs), photovoltaic generators (PVs), conventional gas turbines, energy storage systems (ESSs) and controllable loads (CLs) are integrated into MGs with the price-based demand response (PBDR). Then, a 3-layer coordinate control system framework is designed...
Renewable energy is expected to play much more important role in future low-carbon energy system, however, renewable energy has problems with regard to load-following and regional imbalance. This study aims to plan the deployment of intermittent renewable energy in multiple regions considering the impacts of regional natural conditions and generation capacity mix as well as interregional transmission...
Bio-oil can't be directly used as fuel due to its deteriorate properties. Here, an efficient catalytic upgrading process for the bio-oil, including esterification, hydrogenation, hydrodeoxygenation and depolymerization, is proposed with multifunctional catalyst Ni/SiO2–ZrO2 and biomass-derived solvent ethanol. Results showed that esters, alcohols, phenolics, and cyclo-ketones were the main components...
This paper reports on the development of a two-dimensional, fully nonlinear CFD (Computational Fluid Dynamics) model with dynamic mesh to analyze the performance of a heave-only floating OWC (oscillating water column) device. The model was validated against previous experimental, analytical and numerical results on wave–air–structure interaction of others. The results showed that both the turbine...
A simulation model is proposed in the present study to analyze economic and environmental performance of electric vehicles (EVs) operated under different conditions including electricity generation mix, smart charging control strategies and real-time pricing mechanisms. The model is organized into an input–output framework and actualized using an hour-by-hour computer simulation to achieve a real-time...
A linear piezoelectric actuator based solar panel cleaning system is proposed in order to make a solar panel operate at the best power generation state while the solar panel is used in dusty environment. A piezoelectric actuator linearly moving on a guide is employed to drive a wiper fixed on the actuator. At a proper pressure force between the wiper and solar panel, the actuator can drive the wiper...
Nuclear power has long been a cornerstone of energy policy in Japan, a country with few natural resources of its own. However, following on from the Fukushima Daiichi accident, the Japanese government is now in the throes of reviewing its nuclear power policy. On the other hand, under continuing policies of greenhouse gas reduction, it is crucial to consider scenarios for the country to realize an...
Under continuing policies of CO 2 emissions reduction, it is crucial to consider scenarios for Japan to realize a safe and clean future electricity system. The development plans for nuclear power and renewable energy - particularly solar and wind power - are being reconsidered in light of the Fukushima nuclear accident. To contribute to this, in the present study, three electricity supply...
