Location Planning of Fast Charging Station considering its Impact on the Power Grid Assets
For power grid operators and PEV infrastructure planners, this work addresses the need to balance charging service quality with grid asset protection, though it is an incremental extension of existing planning models.
The paper proposes a multi-objective location planning model for fast charging stations that considers impacts on power grid assets, solved via cross-entropy method. Results on a synthetic network demonstrate the approach's validity.
Under the ambition of boosting Plug-in Electric Vehicle (PEV) charging speed to a level comparable to the traditional refueling, Fast Charging Station (FCS) has been integrated into power distribution system. The location planning of FCS must allow for satisfactory charging service for PEV users as well as mitigate the detrimental effects on power grid caused by uncertainty and impulsiveness of charging demand. This paper proposed a location planning model for FCS, taking into account its impacts on the critical power grid assets. The multi-objective planning model simultaneously considered the role of FCS in the electricity and transportation sectors. This planning model is solved by the cross-entropy (CE) method. The validity and effectiveness of the CE approach have been demonstrated on a synthetic coupled network.
