Market power refers to conditions where the providers of a service can consistently charge prices above those that would be established by a competitive market. There are many well known definitions of market power, including indices intended to quantify the degree of market concentration of energy supplies. This paper explores a method by which one of the standard indices in market power analy...

Accurate modelling of the Electric arc furnace (EAF) is necessary to study its impact on power systems. Here, a new model for EAF presented in which both non-linearity and time-varying characteristics are taken into account. The consists seven parallel current sources represent fundamental harmonic currents. Magnitude phase magnitude second seventh harmonics considered as updated every 0.01 s. ...

wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. in general, these wind power plant...

for multi-objective optimal reactive power dispatch (morpd), a new approach is proposed where simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are achieved. optimal settings of continuous and discrete control variables (e.g. generator voltages, tap positions of tap changing transformers and the number of...

A substantial amount of research effort has been applied to the field environmentally assisted fatigue (EAF) due requirement account for EAF behaviour metals existing and new build nuclear power plants. We present results European project INcreasing Safety in NPPs by Covering Gaps Environmental Fatigue Assessment (INCEFA-PLUS), during which sensitivities strain range, environment, surface rough...
