The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
A decline in energy storage costs increases the benefits of all-scale investments, an increase in electric vehicles promotes the benefits of small-scale investments, expansion of the peak-to-valley price distance increases the benefits of large-scale investments.
Therefore, this part according to the average value of the peak and valley difference remains unchanged, the price difference is reduced by 50 % and 10 %, increased by 10 % and 50 % four scenarios to assess the impact of peak and valley tariff changes on the benefits of light storage and charging mode of integration.
The capacity optimization model of the integrated photovoltaic- energy storage-charging station was built. The case study bases on the data of 21 charging stations in Beijing. The construction of the integrated charging station shows the maximum economic and environment benefit in hospital and minimum in residential.
The economic and environmental benefits of the integrated charging station also markedly differ on different scales: with scale expansion, the rate of return on investment and the carbon dioxide emissions reduction first increase and then decrease.
