The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 699.94 to 2284.23 yuan (see Table 6), which verifies the effectiveness of the method described in this paper.
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
The PV and storage integrated fast charging station now uses flat charge and peak discharge as well as valley charge and peak discharge, which can lower the overall energy cost. For the characteristics of photovoltaic power generation at noon, the charging time of energy storage power station is 03:30 to 05:30 and 13:30 to 16:30, respectively .
Fig. 11 Before and after optimization of charging pile discharge load. The MHIHHO algorithm optimizes the charging pile's discharge power and discharge time, as well as the energy storage's charging and discharging rates and times, to maximize the charging pile's revenue and minimize the user's charging costs.
For instance, the APP of TELD, that is, a leading charging facility manufacturer and operator in China, claims that the DC charging pile's advertised charging power of 60–150 kW is 60 kW, but the highest charging power it is capable of is about 90–100 kW.
The charging power of a single charging pile is 350 kW. The installation and purchase cost of a single charging pile is $34,948.2. The service life of PV, ESS, charging pile, transformer, and other equipment is 15 years. The land cost of charging piles for 15 years is 524.2 $/m 2. The charging pile of a single electric bus covers an area of 40 m 2.
