Abstract Thermostatically controlled loads (TCLs) are regarded as having potential to participate in power grid regulation. This paper proposes a scheduling strategy with three-stage optimization for regional aggregators jointly participating day-ahead support demand response. The first stage is on the profit of and peak load grid. line loss voltage deviation regulation considered ensure stable...

Generator sets cannot operate in a stable fashion in parallel with other sources unless the loading on the generator set is controlled. When generator sets are operating together on an isolated bus (that is, not grid-paralleled), they are commonly provided with equipment to allow each machine to operate at the same percentage of load as the percentage of load on the total system. This is termed...

A doubly fed induction generator (DFIG) designed to be driven at variable speed from a wind turbine and supplying an isolated load is presented. Two back-to-back PWM voltage-fed inverters connected between the stator and the rotor allow suband super-synchronous operation with low distortion currents. The load voltage is maintained at constant frequency and its magnitude is regulated through con...

Causal attribution has been one of the most influential frameworks in the literature of achievement motivation, but previous studies considered achievement attribution as relatively deliberate and effortful processes. In the current study, we tested the hypothesis that people automatically attribute their achievement failure to their ability, but reduce the ability attribution in a controlled m...
