Provision for reactive power market in the reactive power control groups

TENCON 2008 - 2008 IEEE Region 10 Conference, 2008
Implementation of electricity market is facing many challenges in developing countries like India. The market for real power is gaining more interest of investors while the market for reactive power has less incentive due to its technical limitation. But reactive power is of importance for system security and improving the line transmission capacity ...

OPTIMAL CONTROL OF VOLTAGE AND REACTIVE POWER OF POWER SYSTEM

IFAC Proceedings Volumes, 1987
Abstract In this paper, from the view point of economy and security of a power system, a synthetic mathematical model is presented for minimizing system losses and improving voltage level. At the same time, it is taken into account that when the reactive power is insufficient or it is hard to operate the system normally, the system will be supplied ...

Active reactive-power controller

IEE Proceedings - Electric Power Applications, 1995
A novel technique for building reactive power compensators using the switched-capacitor technique is presented. Normally when switched-capacitor are used for reactive power compensation they are operated at the supply frequency; in the proposed technique the capacitors are switched at higher frequencies, typically 800 Hz.

Coordinated Reactive Power-Voltage Controller for Multimachine Power Plant

IEEE Transactions on Power Systems, 2012
This paper presents a newly developed voltage and reactive power control device, the coordinated Q -V controller (CQVC), for a multimachine steam power plant (SPP). The requirements for the new controller are defined based on identified inadequacies of manual Q-V control.

Optimal voltage and reactive power control in power distribution system

Proceedings of the 2nd International Conference on Smart Digital Environment, 2018
The voltage and reactive power control management are the challenging issues of power distribution systems. Since last few years, the installation of renewable or non renewable energy resources (such as wind turbines generator, biomass, solar photovoltaic, fuel cells ...) in power distribution systems is important.

Reactivity and Power Shape Control

Nuclear Science and Engineering, 1977
An optimization method, based on linear programming, has been developed that determines the enrichment distribution in a multizone reactor such that the desired power distribution is achieved at beginning-of-life conditions, as well as the poison distribution during reactor operation such that the reactor is kept critical and the desired power ...

Controlling the flow of real and reactive power

IEEE Computer Applications in Power, 1998
The unified power flow controller (UPFC) is the cornerstone of EPRI's flexible AC transmission system (FACTS) program. FACTS is an evolving technology-based solution envisioned by EPRI to help the electric utility industry deal with the changes in the power delivery business.

Reactive Power Control in Wind Power Plants

2017
Studies in this chapter have been performed on the interaction between wind farm, reactive power compensation, and the power system network. The fluctuation of the loads and the output of wind turbine units in power system have made the reactive power compensation an effective procedure.

Fuzzy optimal reactive power control

Electric Power Systems Research, 1994
Abstract Optimal reactive power control has been an active research area during the last decade. Where precise data are available, a specific objective with clear-cut constraints was the primary requirement. The sensitivity of a feasible solution in the constraint domain has been reported many times.

Reactive power generation and control by thyristor circuits

1976 IEEE Power Electronics Specialists Conference, 1976
Generally, static var generators function as variable reactances (capacitive or inductive impedances) or controllable ac current and voltage sources. Possible methods of var generation and control by static thyristor circuits are reviewed, and new approaches are described in which power frequency changers (cycloconverters) are employed.
