in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...

While automation helps to increase load-shifting, the combination of with time-of-use (TOU) or critical-peak prices (CPP) may lead rebound peaks at beginning low-tariff periods which exceed original peak. Using a discrete choice experiment representative sample 696 Swiss consumers, we find that tariff menu including (i) flat price direct load control (DLC) and (ii) without could avoid this prob...

Tank water heaters (WHs) are present in a prevailing number of European households. Serving as energy buffers WHs have come under the spotlight of various direct load control (DLC) programs over the last few decades. Although DLC has proven to be an efficient measure towards daily peak demand shaving, the payback effect might lead to a new peak in the grid. This payback phenomenon takes place e...

Demand Response (DR) strategies represent an innovative option to optimise energy management. In particular, smart thermostats have captured the attention of scientific community for their effectiveness in achieving energy-saving and peak-shaving by lowering HVAC consumption during critical hours year. One way this aim, is leave control thermostat a third party duration DR event so-called Direc...

The current status of diamond-like carbon (DLC) coatings for biomedical applications is reviewed with emphasis on load-bearing coatings. Although diamond-like carbon coating materials have been studied for decades, no indisputably successful commercial biomedical applications for high load situations exist today. High internal stress, leading to insufficient adhesion of thick coatings, is the e...
