Toward a competitive market for reactive power
IEEE Transactions on Power Systems, 2002This paper presents the design of a competitive market for reactive power ancillary services. Generator reactive power capability characteristics are used to analyze the reactive power costs and subsequently to construct a bidding framework. The reactive power market is settled on uniform price auction, using a compromise programming approach based on ...

Reactive Power Market Demonstration
2021 International Conference on Smart Energy Systems and Technologies (SEST), 2021The network operators in Finland are facing new challenges in reactive power control. This paper focuses on the reactive power flow at the TSO/DSO interface. The motivation is to add the control ability of reactive power by a market-based approach where so far untapped flexible inverter-based resources connected to the distribution system are used as ...

Reactive power consensus in microgrids
2016 European Control Conference (ECC), 2016The use of microgrids for the integration of renewable energy sources and for the electric supply of rural or isolated areas involves a number of problems. One of these is reactive power sharing. Here we propose a consensus based approach to study different control strategies to achieve reactive power sharing and to numerically evaluate their ...

Resolving the reactive power question
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019The definition and measurement of reactive power has been the subject of a sometimes acrimonious debate. In this paper, a number of factors leading to the present situation are exposed by reviewing the history of the matter. The contributions of Poynting (1884), Steinmetz (1892), Lyon (1920) and Budeanu (1927) are examined. It is shown that much of the

Reactive Power Control of Compound Reactive Power Compensation Device
2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018A low-cost composite reactive power compensation model is proposed. The model consists of a Thyristor Switched Capacitor (TSC), a Thyristor Controlled Reactor (TCR) and a Static Var Generator (SVG). Firstly the paper completes the preliminary compensation by the large-capacity TSC+TCR module, and then the small-capacity SVG is responsible for ...

Zone Reactive Power Controller
2018 IEEE 4th International Forum on Research and Technology for Society and Industry (RTSI), 2018In this paper zone reactive power controller is presented. Power network is naturally divided into voltage areas which are semi-independent or, at least, have no significant impact on neighbouring areas. Natural voltage areas, zones, represent the impact range of control actions performed in a certain zone.

A Reactive Power Model for a Simultaneous Real and Reactive Power Dispatch
2007 IEEE Power Engineering Society General Meeting, 2007This paper investigates the simultaneous dispatch of real power and reactive power in restructured electricity markets. In this proposed method the opportunity cost of supplying reactive power is implicitly modeled using the rating of the machine as a constraint.

Reactive power and power factor
Electrical Engineering, 1933GENERAL definitions exist for potential, current, and active and reactive power, that are independent of wave form and of circuit conditions. In order to use these quantities in circuit analysis when there are harmonics present, it is necessary to know their individual harmonic components.

Transactions of the American Institute of Electrical Engineers, 1933
In this paper the single-phase and polyphase definitions of reactive power are considered. The single-phase definition is unsatisfactory when the current and voltage wave forms are complex. The polyphase definition is the better but requires the independent recognition of the effects of distortion and, in the case of four or more wires, mesh ...

Provision for reactive power market in the reactive power control groups
TENCON 2008 - 2008 IEEE Region 10 Conference, 2008Implementation 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 ...
