When crack problems are analyzed on the basis of nonlinear theories, such as finjte elasticity or deformation theory of plasticity, it is inevitable that nonlinear effects will predominate near a crack-tip, even if the loads are small. The most favorable circumstance in this regard occurs when the loads are so small that the zone of significant nonlinearity lies within the region of validity of...

In this paper, an optimal scheduling of thermal and wind power plants is presented by using a stochastic programming approach to cover the uncertainties of the forecasted generation of wind farms. Uncertainties related to wind forecast error, consequently wind generation outage power and also system load demand are modeled through scenario generation. Then, with regard to day-ahead and real-tim...

With the rapid development of local economy, frequent occurrence extreme climates, and increase in scale new energy installations, short-term peak loads have repeatedly reached highs, characteristics power system "double high, double peaks, double-sided random" will be further highlighted, making grid supply demand Balance faces greater challenges. In this context, role electricity response has...

the theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. in elastic deformation contact occurs over a finite area. a regular method for determining the dimensions of this area is hertz contact model. appearance of atomic force microscope results in introduction of contact mechanics into biology. low elastici...

Building a new power system with renewable energy as its main component is key measure proposed by China to address the climate change problem. Strengthening demand-side management (DSM) an important way promote development of system. As economic incentive in DSM, current TOU tariff faced problem weak effect due small difference between peak and valley periods. Against this background, novel hy...
