Control of Stacked Power Electronics Systems

2021 55th Annual Conference on Information Sciences and Systems (CISS), 2021
Series-connected power electronics converters are commonly used in applications where low-distortion multilevel waveforms are needed or the overall system voltage exceeds the ratings of the individual converter. Two notable use-cases are modular multilevel converters and solid-state medium-voltage transformers. In such systems, control is traditionally

The ITER Power and Particle Control System

Fusion Technology, 1996
The ITER power and particle control system is designed to exhaust the 300 to 400 MW of alpha and auxiliary heating power and the 5 x 10{sup 20} He atoms per second created by the fusion reactions, to control the density and to fuel the plasma. The power and particle control system consists of a single null poloidal divertor, a set of active pumps with ...

HYDROELECTRIC POWER STATION CONTROL SYSTEMS

IFAC Proceedings Volumes, 1986
Summary EDF runs 460 unattended hydroelectric power stations. The many years of experience acquired has enabled EDF to write formal guidelines on automation, which are all the more necessary because hydroplant is increasingly used for load following and power system control.

Hierarchical optimization and control of a power system

ISGT 2014, 2014
A massive transformation of the power grid is undergoing towards the smart grid concept. Devices such as smart meters, inverter interfaced power devices, energy storage, power electronics equipment, smart appliances and other controllable devices are being incorporated in the power grid.

Intelligent power system controller design

International Journal of Computer Applications in Technology, 2019
In this paper, a type-2 fuzzy-based adaptive sliding mode power system controller is proposed for damping low-frequency oscillations with the aim to enhance power system stability despite model uncertainties introduced by variations of system parameters and external disturbances.

Power flow controllers in DC systems

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
Constructing multi-terminal high voltage dc (HVDC) systems can effectively make it possible for the large-scale new energy to be integrated into the grid and make up the defects of the existing ac power system. When constructing the multi-terminal dc system, one cannot avoid the problem that how to control the dc power flow effectively.

A computer model for power system control

Computers & Operations Research, 1987
A forward dynamic programming formulation of the optimal commitment of units for economic power generation is proposed, and it is shown how advantage is taken of the characteristics of the formulation as well as the structure of the problem itself to impose limiting conditions which reduce the size and complexity of the solution, while still ensuring ...

Corrosion Control in Electric Power Systems

Electric Machines & Power Systems, 1999
The electrochemical mechanism of aqueous corrosion is outlined, and it is demonstrated that the process depends on a complex interaction between the material and its environment given the particular circumstances of exposure. Failure to recognize the full implications of the environment or the circumstances will often lead to unexpected corrosion ...

Controlling power systems with price signals

Decision Support Systems, 2005
This paper revisits the possibility of controlling the power system entirely by means of price signals. It expands on notions introduced in an earlier paper and addresses several unresolved issues: problems with linear cost structures, response delays, varying costs, market power and stability problems caused by market/system interactions.
