In the last few years, there has been an exponential increase in the penetration of electric vehicles (EVs) due to their eco-friendly nature and ability to support bidirectional energy exchanges with the power cyber-physical system. However, the existing research only proposes energy management in terms of vehicle-to-grid (V2G) support using fleets of EVs, which lacks research on EV attacks. Motivated by these facts, this paper first introduces a new data integrity attack strategy for a consistent energy management algorithm which considers electric vehicles as energy storage. In particular, we consider EV aggregators as energy storage with source-charge bidirectional characteristics. The attacker carefully constructs false information to manipulate aggregators to participate in scheduling and obtaining additional benefits on the premise of meeting the constraints of microgrid and various devices by attacking the consistent algorithm. Then, we propose a disturbance rejection control strategy combining privacy protection protocols and an isolation mechanism. We analyze the effectiveness of the proposed encryption mechanism and verify the feasibility of the isolation control algorithm by simulation and comparison.

“…In some studies, only smart unidirectional charging was examined [13]; in others, the bidirectional charging of EVs [14][15][16][17][18][19]. Some focused on a building energy system ( [18]), while others examined the impact on local grids (commercial, industrial, and parking lots) [20,21].…”

Electricity storage systems, whether electric vehicles or stationary battery storage systems, stabilize the electricity supply grid with their flexibility and thus drive the energy transition forward. Grid peak power demand has a high impact on the energy bill for commercial electricity consumers. Using battery storage capacities (EVs or stationary battery systems) can help to reduce these peaks, applying peak shaving. This study aims to address the potential of peak shaving using a PV plant and smart unidirectional and bidirectional charging technology for two fleets of electric vehicles and two comparable configurations of stationary battery storage systems on the university campus of Saarland University in Saarbrücken as a case study. Based on an annual measurement of the grid demand power of all consumers on the campus, a simulation study was carried out to compare the peak shaving potential of seven scenarios. For the sake of simplicity, it was assumed that the vehicles are connected to the charging station during working hours and can be charged and discharged within a user-defined range of state of charge. Furthermore, only the electricity costs were included in the profitability analysis; investment and operating costs were not taken into account. Compared to a reference system without battery storage capacities and a PV plant, the overall result is that the peak-shaving potential and the associated reduction in total electricity costs increases with the exclusive use of a PV system (3.2%) via the inclusion of the EV fleet (up to 3.0% for unidirectional smart charging and 8.1% for bidirectional charging) up to a stationary battery storage system (13.3%).
