Modelica is an object oriented modeling language that allows straightforward specification of differential,algebraic and discrete equations in a standardized format. It has been used in a number of applications to support multi-domain system simulations such as are found in the automotive and aerospace industries. More recently it has begun to be used in the power systems industry. Modelica models...
This paper presents an optimal demand response pricing model for smart grids. A physical Transmission and distribution grid simulation model with renewable power sources is built to calculate optimal demand response price strategies that maximize peak load shifting and grid efficiency. A parallel PSO (Particle Swarm Optimization) solver implemented on an HPC (High Performance Computing) platform is...
Along with rapid economic growth, urban traffic has become a complicated worldwide issue, which synthesizes out-of-order jam, energy consumption and GHG emission. An autonomic traffic and energy model is proposed based on the micro behavior simulation, in which an information decision factor is introduced. Thus the travel patterns and choice of the road trip have been controlled and optimized dynamically...
From 1980 to 2002, China experienced a 5% average annual reduction in energy consumption per unit of gross domestic product (GDP). With a dramatic reversal of this historic relationship, energy intensity increased 5% per year during 2002–2005. China's 11th Five Year Plan (FYP) set a target of reducing energy intensity by 20% by 2010. This paper assesses selected policies and programs that China has...
This paper presents an overview of the initiatives launched in energy supply and consumption and the challenges encountered in sustainable road transportation development in China. It analyzes the main energy challenges related to road transportation development arising in the context of economic development, rapid urbanization, and improvement in living standards. It also discusses technological-...
Urban traffic has become a worldwide problem with the economy developing rapidly, which synthesizes out-of-order jam, energy consumption and GHG emission. An autonomic model is proposed based on the micro behavior simulation of urban traffic, in which an information decision factor is introduced. Thus the travel patterns and choice of the road trip have been controlled and optimized dynamically. Simulation...
