Illustrating the conflicts of the energy transition: energy poverty vs decarbonisation. A case example in Spain
Although the energy transition is generally understood as the decarbonization of the energy sector, other elements, such as atmospheric pollutants mitigation, job creation, energy security, or reducing energy poverty, must ... -
Impact assessment of FCUC on optimal design of UFLS settings in Island Power Systems
A frequency constrained unit commitment (FCUC) formulates the non-linear, non-convex frequency dynamics to obtain the generation dispatch of island power systems (IPSs). Even with FCUC, under frequency load shedding (UFLS) ... -
Impact investing: a new paradigm to philanthropy from finance and ethical theories.
La inversión de impacto reconoce aquellas iniciativas que tengan un retorno híbrido, entre la rentabilidad financiera y social y / o la devolución del medio ambiente. Este fenómeno está creciendo en los últimos años gracias ... -
Impact of AC-line-emulation controllers of VSC-HVDC links on inter-area-oscillation damping
This paper presents a fundamental study on the impact of AC-line-emulation controllers of High Voltage Direct Current links based on Voltage Source Converters (VSC-HVDC) on inter-area-oscillation damping. The analysis has ... -

Impact of current limiters and fast voltage boosters in grid-forming VSC-based generators on transient stability
Transient stability is a complex phenomenon presented in multi-machine and multi-converter systems, and it is still considered a key limiting factor for stressed power systems. The increasing integration of non-synchronous ... -
Impact of different EV charging strategies in the Spanish and Greek power systems
Electric vehicles (EVs) can help decarbonise the transportation sector, which is responsible for a great share of greenhouse gas (GHG) emissions. However, electric companies are concerned about the effects of introducing ... -
Impact of electric vehicle routing with stochastic demand on grid operation
Given the rise of electric vehicle (EV) adoption, supported by government policies and dropping technology prices, new challenges arise in the modeling and operation of electric transportation. In this paper, we present a ... -
Impact of fatigue cycling costs on CCGT operations
Combined cycle gas turbine power plants (CCGTs) play a key role in modern electric power systems due to their operational flexibility and the firmness they provide to the networks where they operate. Due in part to this ... -
Impact of gas third party access in the unit commitment optimal solution
The importance of the natural gas sector in the electric power industry has increased substantially over the last decades, reaching 21 generation capacity in Europe in 2016. Generation companies that own gas fired units ... -
Impact of international obligations related to environmental protection on three main constitutional areas of concern: balance of rights, general freedom principle and internal territorial divisions
La comunicación versa sobre el impacto de las obligaciones medioambientales impuestas por el Derecho internacional sobre tres áreas tradicionales del Derecho constitucional: el equilibrio entre derechos y principios, el ... -
Impact of PLL control on small-signal stability of wind DFIGs
This paper investigates the small-signal stability of wind doubly fed induction generators. Precisely, the impact of the phase locked loop control on the small-signal stability of wind doubly fed induction generators is ... -
Impact of PLL control on small-signal stability of wind DFIGs connected to weak grids
Research into doubly-fed induction generator (DFIG) technology has yet to solve the instability that arises when DFIGs are connected to weak grids. To investigate this problem, this work used the modal analysis technique ... -
Impact of the q-axis sub-transient reactance on the rotor oscillations of a hydro generator
In the process of refurbishing a hydro generator, the owner has requested manufacturers to supply a machine that exhibits the same electrical parameters than the old one. The selected supplier has informed that such ... -
Impact of turbogenerator uprating on its transient response in case of grid events
The process of increasing the licensed power level of a commercial Nuclear Power Generating Station (NPGS) is called a power uprate. Power uprates have been implemented at a number of NPGSs in many countries. Such uprates ... -
Impact on power system transient stability of AC-line-emulation controllers of VSC-HVDC links
High voltage direct current links based on voltage source converters (VSC-HVDC) embedded in alternating current (AC) systems are receiving a great deal of attention recently because they can contribute positively to the ... -
