In a competitive environment reactive power management is an essential service provided by independent system operator taking into account the voltage security and transmission losses. The system operator adopts a transparent and non-discriminatory procedure to procure the reactive power supply for optimal deployment in the system. Since generators’ are the main source of reactive power generat...

This paper presents a new multi-objective coupled energy and reactive power market clearing model namely the MO-CERPMC model in day-ahead competitive market environment. In proposed model, both the active and reactive power markets are considered as coupled markets and cleared in a same time frame. The multi-objective optimization problem involves the minimization of total payment functions for...

Reactive power planning is one of the most challenging problem for efficient and source operation of an interconnected power network. It requires effective and optimum co-ordination of all the reactive power sources present in the network. Recently, Teaching Learning Based Optimization (TLBO) algorithm is evolved and finds its application in the field of engineering optimization. In the propose...

Considering time-harmonic optical fields, we put forward the complex helicity and its alternating flow, together with their conservation equation: theorem. Its imaginary part constitutes a novel law that rules build-up of what establish as reactive through zero time-average flow. associated flow Poynting momentum accounts for accretion power are illustrated in two paradigmatic systems: evanesce...

This paper provides the theoretical basis for the measurement of reactive and distortion powers from the wavelet transforms. The measurement of reactive power relies on the use of broad-band phase-shift networks to create concurrent in-phase currents and quadrature voltages. The wavelet real power computation resulting from these 90 phase-shift networks yields the reactive power associated with...

This chapter was prepared primarily for "non power" engineers to introduce reactive power and voltage control concepts, and to identify several issues that remain as research challenges in this area. It begins with basic definitions and information on reactive power, and then focuses on problems that have been known for many years and have surfaced recently in power system operations. These pro...

In this paper, an optimal strategy is proposed for the reactive power allocation in large-scale grid-connected photovoltaic systems. Grid-connected photovoltaic systems with direct current to alternating current inverters are able to supply active power to the utility grid as well as reactive power. The active power, extracted by the direct current to alternating current inverters, is usually c...
