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...

We examined the attentional demands of the preparation process that intervenes a warning stimulus (S1) and a subsequent reaction stimulus (S2). Twelve participants performed a reaction task with a variable S1–S2 interval both with and without concurrent memory load that served to deplete attentional resources. We found that memory load did not modify the effect of the S1-S2 interval on reaction...

Mamdani and Takagi-Sugeno fuzzy controllers were prepared. The controllers were designed using Fuzzy Logic Toolbox. The membership functions and rules were used as design tools that give opportunity to model a control surface and controller properties. The control system of d.c. (direct current) motor drive with two feedback loops is considered. First loop is used for stabilization of armature ...

This paper presents novel corrective control actions to alleviate overloads in transmission lines by the Particle Swarm Optimization (PSO) method. Generator rescheduling and/or load shedding is performed locally, to restore the system from abnormal to normal operating state. The appropriate identification of generators and load buses to perform the corrective control action is an important task...

The modernization of the electrical grid and the installment of smart meters come with many advantages to control and monitoring. However, in the wrong hands, the data might pose a privacy treat. In this paper, we consider the tradeoff between smart grid operations and the privacy of consumers. We analyze the tradeoff between smart grid operations and how often data is collected by considering ...

The authors consider a power system composed of several non-synchronous AC areas connected by a multi-terminal high-voltage direct current (HVDC) grid. In this context, the authors propose a distributed control scheme that modifies the power injections from the different AC areas into the DC grid so as to make the system collectively react to load imbalances. This collective reaction allows eac...

ORK-LOAD CONTROL FACTORS in clinical laboratories are not available in the literature. Business engineering and manpower-study methods are not readily applicable to laboratory work in which varied human elements exist. The remarkable variety of methods, choice of technics, personal viewpoints, lack of contacts, and few chances for direct comparison with the work of others in the field also make...

The performance of direct methanol fuel cell (DMFC) is closely related to its operating conditions, and there exists a specific combination of operating conditions at which the DMFC output maximum power to the driven load. Working at maximum power point (MPP) can lower the methanol crossover and ancillary power consumption so as to improve the global efficiency of the system. The fuzzy controll...

As an important part of energy Internet carrier, demand side resources can participate in many interactions with power grid. In order to reduce the peak valley load difference grid, from perspective tapping combined shaving potential air conditioning and electric vehicles, guided by TOU price direct control, this paper proposes optimal scheduling model minimum maximum total revenue users as obj...

PID controllers are very common in industrial systems applications. The tuning of these controllers is governed by system nonlinearities and continuous parameter variations. In this paper, a complete and rigorous comparison is made between two tuning algorithms. The PI controller was used in a speed control loop in a Direct Torque Control (DTC) scheme applied on an induction motor. The first me...
