4.1. Parameter configuration Take a highway charging station as the test case, which is with 20 charging piles, including a wind farm, a photovoltaic power generation, and an ESS. The 20 charging piles are subdivided into 16 ultra-fast charging piles and 4 fast charging piles.
The charging pile types of highway charging stations can generally be divided into ultra-fast charging (Liquid-cooled charging piles) and fast charging piles (Air-cooled charging piles), so the power limits of EVs can be divided into two categories. Pp1,min and Pp2,min is the minimum charging power of ultra-fast charging and fast charging piles.
