“…EV load models exposed in Equation (1) are also considered for loads connected to buses 18, 21 and 24, equivalent to 40 %, 20 % and 30 % of total active load connected to the bus. The parameters of EV load models are selected according to (Dharmakeerthi, Mithulananthan and Saha, 2014). The selected parameters consider the worst-case scenario for voltage stability, which corresponds to the most negative value for the exponent of EV load model.…”

“…Recently in (Dharmakeerthi et al, 2014), the authors propose a combination of constant power and an exponential load model with negative a for static voltage stability purposes. This negative characteristic is due to the influence of the parasitic resistance of the input filter inductor.…”

“…Several studies on grid impacts associated with EV charging were proposed; steady-state voltage stability has been analyzed in (Dharmakeerthi, Mithulananthan & Saha, 2014) (Mitra & Venayagamoortghy, 2010), small signal stability in (Das & Aliprantis, 2008), influence in grid load capacity in (Hadley, 2006) and power quality in (Richardson, Flynn & Keane, 2010) (Garcia & Pecas, 2013), among others. However, as mentioned above, the presence of these loads in studies may imply exigent computational Associated professor at Universidad Tecnológica de Pereira, Pereira, Colombia.…”

Current electric power systems have an increasing penetration of electric vehicles, and its effect has to be considered in different studies, such as optimal dispatch or voltage stability, among others. Additionally, considering that power system analysis becomes complex when the number of buses increase, this paper presents a methodology for aggregation of load areas that use a measurementbased load modeling approach based on an evolutionary computational technique and a classical reduction method. This aggregate load area model is proposed to reduce areas that consider electric vehicle (EV) load models. The proposed method provides a static equivalent load model and an equivalent network that can be used to reduce the computational effort required by power system studies. In order to validate the application of the proposed methodology, a 30-bus power system considering several disturbances and levels of penetration of the electric vehicles was used. The results show that the equivalent network model allows the reproduction of different events with an acceptable accuracy when it is compared to the original system behavior.Keywords: Reduction of power systems, measurement-based load modeling approach, electric vehicle, particle swarm optimization. RESUMENCon la inclusión de los vehículos eléctricos en las redes de energía es necesario analizar su impacto en los diferentes estudios, como el caso del despacho óptimo o análisis de estabilidad de tensión, entre otros. Debido a que el análisis de los sistemas de potencia se hace más complejo a medida que se incrementa el número de barras, en este artículo se presenta una metodología para la agregación de áreas de carga, que emplea el modelado de carga basado en mediciones, que a su vez se basa en una técnica computacional evolutiva y un método clásico de reducción. Se propone este modelo de agregación de área de carga con el fin de reducir áreas que contienen modelos de carga de vehículos eléctricos. El método propuesto provee un modelo equivalente estático de carga y de la red, que puede emplearse para reducir el tiempo computacional requerido para análisis específicos en la red. La metodología propuesta se valida en el sistema modificado IEEE de 30 barras, ante diferentes perturbaciones y diferentes niveles de penetración de los vehículos eléctricos. Los resultados muestran que el equivalente de red obtenido permite reproducir los diferentes eventos con una aceptable exactitud en comparación con el comportamiento del sistema original.Palabras clave: Reducción de sistemas de potencia, modelado de carga basado en mediciones, vehículo eléctrico, optimización por enjambre de partículas.

“…The results showed PEVs can be utilized to system reserve with suitable charging and discharging strategies, although increased system loading from uncontrolled PEVs may weaken system reliability. Dharmakeerthi et al [21] further evaluated the impact of PEVs on voltage stability in a distribution network based on an original static load model. They discovered that PEV fast-charging stations may substantially aggravate steady-state voltage stability on some local nodes.…”

Abstract:The market share of electric vehicles is growing and the interest in these vehicles is rapidly increasing in industrialized countries. In the light of these circumstances, this study provides an integrated policy-making package, which includes key features for electric vehicle diffusion and its impact on the Korean power market. This research is based on a quantitative analysis with the following steps: (1) it analyzes drivers' preferences for electric or traditional internal combustion engine (ICE) vehicles with respect to key automobile attributes and these key attributes indicate what policy makers should focus on; (2) it forecasts the achievable level of market share of electric vehicles in relation to improvements in their key attributes; and (3) it evaluates the impact of electric vehicle diffusion on the Korean power market based on an achievable level of market share with different charging demand profiles. Our results reveal the market share of electric vehicles can increase to around 40% of the total market share if the key features of electric vehicles reach a similar level to those of traditional vehicles. In this estimation, an increase in the power market's system generation costs will reach around 10% of the cost in the baseline scenario, which differs slightly depending on charging demand profiles.

“…EV loads have nonlinear characteristics, which is different than the general industrial or domestic loads, and draw large quantities power in a short time period [82,128]. [129] corroborated to the fact that EVs cause serious voltage instability in power systems. If the EVs have constant impedance load characteristics, then it is possible for the grid to support a lot of vehicles without facing any instability [82].…”

Electric vehicles (EV) are getting more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace the internal combustion engine (ICE) vehicles in near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system can face huge instabilities with enough EV penetration; but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of smart grid. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emission from the transportation sector. However, there are some major obstacles for EVs to overcome before replacing the ICE vehicles totally. This paper is focused on reviewing all the useful data available on EV configurations, energy sources, motors, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector.
