“…Therefore, the PEVs in the electrical network were represented by using the battery charger, which also converts the AC-DC converter for charging the battery. In order to define it in normal charging mode, the charger can be represented by the character instant of time as an algebraic function by using the exponential model, as in [34]. So, Equations (10) and (11) are concerned the load power factor value of the battery charger and will be considered when connected into the grid.…”

“…The static load model consists of voltage dependency and frequency dependency of the load characteristics [33]. The battery charger in normal mode charging is represented by the characteristics of the PEVs, which is described in an exponential load by laboratory testing [34]. Many researchers have studied and found the impact of the PEVs on the electrical power system network as discussed in previous paragraphs, but they did not clarify and consider the actual behavior of the PEVs under voltage-dependent power flow analysis.…”

This paper proposes the impact of plug-in electric vehicles (PEVs) integrated into a power distribution system based on voltage-dependent control. The gasolinegate situation has many people turning to electric vehicles as a more environmentally friendly option, especially in smart community areas. The advantage of PEVs is modern vehicles that can use several types of fuel cells and batteries as energy sources. The proposed PEVs model was developed as a static load model in power distribution systems under balanced load conditions. The power flow analysis was determined by using certain parameters of the proposed electrical network. The main research objective was to determine the voltage magnitude profiles, the load voltage deviation, and total power losses of the electrical power system by using the new proposed methodology. Furthermore, it investigated the effects of the constant power load, the constant current load, the constant impedance load, and the plug-in electric vehicles load model. The IEEE 33 bus system was selected as the test system. The proposed methodology assigned the balanced load types in a steady state condition and used the new methodology to solve the power flow problem. The simulation results showed that increasing the plug-in electric vehicles load had an impact on the grids when compared with the other four load types. The lowest increased value for the plug-in electric vehicles load had an effect on the load voltage deviation (0.062), the total active power loss (120 kW) and the total reactive power loss (80 kVar), respectively. Therefore, this study verified that the load of PEVs can affect the electrical power system according to the time charging and charger position. Therefore, future work could examine the difference caused when PEVs are attached to the electrical power system by means of the conventional or complex load type.

Abstract. The deregulation of the electric energy market and the difficulties related to distribution network such as the congestion, the increasing growth of the installed power density in urban zones, the growth of the delivery-provided energy and the spectacular increase that the peak power experiences are new problems to be faced by the utility engineers. So, the knowledge of the load behaviour is becoming more and more important in the planning and operation of the electric energy distribution network.In this paper, the influence of domestic air conditioning equipment, one of the most energy consuming domestic loads in Spain, in the electrical energy distribution network is addressed. The research is focused on analysis of the voltage supply effects on the operation of home air condition appliances, from a theoretical point of view. Some load models of the domestic air conditioning appliances as electrical load are considered.

“…The problem of modeling such an aggregate load is not easy to address. Indeed, while typical data can be obtained for every individual equipment [48], the real problem is to determine the composition of the load. The latter varies from one bus to another but also with the season, the time of the day, etc.…”
