CONCEPT OF REAL AND REACTIVE POWER

2007
In this chapter the meaning of “real” and “reactive” power is explored for sinusoidal systems. Initially, single phase (so-called two-wire) circuits are discussed to gain an understanding of the energy flow within a circuit configuration that is representative for electrical machines.

Reactive power optimisation of power system with APPM

International Journal of Computing Science and Mathematics, 2013
Artificial plant optimisation algorithm is a new stochastic optimisation algorithm inspired by the plant growing process. In this paper, the primary version is applied to solve reactive power optimisation of power system. To show the efficiency, IEEE118 bus systems is employed. Simulation results show it is effective.

Toward a Competitive Market for Reactive Power

IEEE Transactions on Power Systems, 2002
This 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 ...

ITER Reactive Power Compensation Systems: analysis on reactive power sharing strategies

2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019
The goal of nuclear fusion is one of the most important challenges in contemporary research and technological development. Its achievability will completely change the energy scenario and reduce the dependence on fossil fuels in the production of electricity. ITER project is focusing the efforts of many countries and researchers in the demonstration of

Assessing the value of reactive power service using OPF of reactive power

2005 IEEE Russia Power Tech, 2005
This paper describes an approach for the optimal power flow (OPF) problem when reactive power supply is priced at marginal cost. This method computes the reactive power and voltage schedules minimizing the total reactive power cost. This allows obtaining curves of needs that would be the beginning for assigning the value of the reactive power ...

Towards reactive power markets. Part 1: reactive power allocation

IEE Proceedings - Generation, Transmission and Distribution, 2006
Although real power is the main traded commodity in electricity markets, reactive power plays a crucial role in power systems reliability and security. In competitive electricity markets, no market participant wants to subsidise others in any way. Market participants utilise the network in different ways to maximise their profits.

Reactive power and magnetic energy

Journal of the American Institute of Electrical Engineers, 1920
The relation between reactive power and magnetic and electrostatic energies is stated and proved and its utility is illustrated by deriving the connection between reactive power and the size of machines, between the magnetic energy of an a-c. system and the field excitations of the synchronous machines therein, and by giving the physical significance ...

Power, reactive volt-amperes, power factor

Electrical Engineering, 1933
The relation between power, reactive volt-amperes, and power factor is discussed for sinusoidal electromotive forces and currents. Reactive volt-amperes is defined as the flow of stored energy into the circuit and is deduced from the stored energy cycle.
