An Algorithm to Enhance the Profit Margin of Electric Vehicle Owners and Resilience of Multi-microgrid Using EV

Improvement in the electric vehicles (EVs) area and the expanding number and greatness of catastrophic events have drawn in the consideration of analysts to use the put-away energy in EVs and upgrade the versatility of force frameworks. Microgrids are viewed as a possible source to take care of these issues. Nearby assets accessible in the microgrid are utilized to improve the strength of the system, for example, battery energy storage system. An extra battery energy storage system to improve the resiliency of the system might prompt an expansion in capital expenses. Consequently, in this article, existing EVs in the microgrid parking lot is utilized revenue-driven acquiring and flexibility upgrades with next to no extra capital expense. In the normal operation scenario, using the proposed strategy EV energy is sold to the MGs in the system offering the highest bidding cost, resulting in raise in the profit margin for the EV owners. In the case of contingencies, the proposed scheme supplies energy from grid-connected microgrids to islanded microgrids through accessible EVs. The strategy to supply energy is carried out in three steps. In the first step, required energy and available energy in the EVs is informed to the central energy management system (CEMS). In the second step, CEMS decides the microgrid to supply energy to the islanded microgrid among grid-connected microgrids. Finally, the microgrid chosen by the CEMS to supply energy to islanded microgrid concludes which EV ought to be sent among the accessible EVs. Simulations have been carried out to show the viability of the proposed scheme.

Automated summary

Improvements in the field of electric vehicles and the increasing number of catastrophic events have resulted in researchers exploring the use of stored energy in EVs to enhance the flexibility of power systems. Microgrids are seen as a potential solution to address these issues. This article proposes a revenue-driven acquisition and flexibility enhancement strategy using existing EVs in a microgrid parking lot with minimal additional capital expenditure. The viability of the proposed scheme is demonstrated through simulations.
