Short-term interaction between electric vehicles and microgrid in decentralized vehicle-to-grid control methods

Abstract

In this paper, a particular standard MicroGrid (MG) is accurately simulated in the presence of the Electric Vehicles (EVs) participating in decentralized primary frequency control service. It examines effect of number of the participating EVs on the short-term dynamic behaviour. The simulation results confirm that frequency deviation will not definitely become zero even though an unlimited number of the EVs participate. The output power of each EV is determined according to the frequency deviation. On the other hand, the output power of each EV affects the value of the frequency deviation, especially in small-scale MGs and MGs with predominant inductance behaviour. Eventually, an equilibrium point is reached after a new EV is added that depends on the characteristics of the MG and the functions executed in the MG central controller during such a service. Additionally, effect of Reflex method, an advanced charging technique for EVs, on the frequency deviation is examined.

Optimal allocation of distributed generation and electric vehicle charging stations based on intelligent algorithm and bi‐level programming

“…In the DG planning scheme, 13 (8) indicates that 8 distributed generators are installed in nodes 13, and in the EVCSs planning scheme, 20(237) indicates that the capacity of the charging station in node 20 is 237 kW.…”

“…Therefore, strategy 1 is superior to strategy 2, and strategy 1 is the best of the three strategies.

Intelligent Classification Method for Grid-Monitoring Alarm Messages Based on Information Theory

“…Using alarm messages for grid monitoring, Supervisory Control and Data Acquisition (SCADA) systems display the operation of power grids to supervisors, and alarm messages also constitute a data basis for fault diagnosis and decision analysis [1,2]. With renewable energy and electric vehicles now connected to power grids, power data are becoming more abundant, and such data are highly valuable [3][4][5]. These data are stored in databases in the form of audio, text, and images [6].…”
