What is a photovoltaic-energy storage-integrated charging station (PV-es-I CS)?

As shown in Fig. 1, a photovoltaic-energy storage-integrated charging station (PV-ES-I CS) is a novel component of renewable energy charging infrastructure that combines distributed PV, battery energy storage systems, and EV charging systems.

What is a Sungrow energy storage system?

Sungrow energy storage system solutions are designed for residential, C&I, and utility-side applications, including PCS, lithium-ion batteries, and energy management systems.

Is solar irradiance a catalyst for energy production in PV systems?

Since irradiance is the primary catalyst for energy production in PV systems (Nasrin et al., 2018), the environmental analysis plugin Ladybug, which is widely used in Rhinoceros software, was applied to simulate solar irradiance for the selected 295 EVCSs to assess the solar energy generation potential of each charging station.

Can photovoltaic-energy storage-integrated charging stations improve green and low-carbon energy supply?

The results provide a reference for policymakers and charging facility operators. In this study, an evaluation framework for retrofitting traditional electric vehicle charging stations (EVCSs) into photovoltaic-energy storage-integrated charging stations (PV-ES-I CSs) to improve green and low-carbon energy supply systems is proposed.

Can LSTM model predict solar power generation in Wuhan?

To predict the PV power generation of the PV-ES-I CS system around each building type, an LSTM model was used to forecast future solar radiation in Wuhan. Using Python 3.6 software, we input hourly solar radiation data for Wuhan from January 1, 2020, to January 31, 2023 (a total of 27,048 h), with an interval of 24 data points.

Do PV production capacities vary within the effective power generation period?

To analyze the variation in and distribution of PV production capacities within the effective power generation period, data cleaning was performed for the data corresponding to zero production or values infinitely close to zero production.
