Charging Station and Power Network Planning for Integrated Electric Vehicles (EVs)

Abstract

The optimal location and size of charging stations are important considerations in relation to the large-scale application of electric vehicles (EVs). In this context, considering that charging stations are both traffic service facilities and common electric facilities, a multi-objective model is built, with the objectives of maximizing the captured traffic flow in traffic networks and minimizing the power loss in distribution networks. There are two kinds of charging stations that are considered in this paper, and the planning of EV charge stations and distribution networks is jointly modelled. The formulated multi-objective optimization problem is handled by a fuzzy membership function. The genetic algorithm (GA) is used to solve the objective function. In case studies, a 33-node distribution system and a 25-node traffic network are used to verify the effectiveness of the proposed model. The location and capacity of two kinds of charging stations are designed in the case studies, after which the impact of the battery on the captured traffic flow is analyzed as well.

Selecting Locations of Electric Vehicle Charging Stations Based on the Traffic Load Eliminating Method

“…Where n i is the number of chargers required to meet the target latency at the i-th station. Equation (13), which is an objective function, minimizes N the total number of fast chargers at all of the charging stations in the area (i). Its constraint is that the number of chargers be set so that the waiting time of EVs for charging at all of the charging stations is less than or equal to that of the waiting time for internal combustion engine vehicles at gas stations.…”

“…While government funding and investment are prerequisites for the expansion of EVSE, academic studies should also provide methods that enable EVSE to be cost effective [3][4][5][6][7][8][9]. In this context, many studies are being conducted on selecting EVSE locations across cities in Korea [10][11][12][13][14][15][16][17][18][19][20]. However, the analysis of EV charging demands must precede the selection of EVSE locations.…”

A Review on Communication Standards and Charging Topologies of V2G and V2H Operation Strategies

“…In such stations, the chargers are specified in three levels on the basis of their charging power and charging circuit [63]. Queuing models according to these levels helps to design the stochastic resource-sharing network to accommodate the convoluted distribution [64] and traffic [65,66] networks to make V2X more accessible.…”

The ElectricalVehicle Simulator for Charging Station in Mode 3 of IEC 61851-1 Standard

“…If the renewable energy is used for charging electrical vehicles (EVs), then we can consider these vehicles with zero emissions [17]. In this context, as the number of electrical vehicles (EVs) will increase, it will also be necessary to increase the number of the charging stations which will have a negative impact on the power quality of the power network (Overvoltage, Voltage Sag) [18][19][20][21][22]. But, with the increase in the number of charging stations installed, the problem will be to carry out their maintenance.…”

“…In the European Union and other countries that accept the standard International Electrotechnical Commission (IEC) 61851-1, it is used for charging stations. The standard is intended for defining general requirements for charging stations [20][21][22], used together with other standards (Ex. IEC 61851-22).…”
