What is a PV power generation dataset?
The dataset comprises measured PV power generation data and corresponding on-site weather data gathered from 60 grid-connected rooftop PV stations in Hong Kong over a three-year period (2021-2023). The PV power generation data was collected at 5-minute intervals at the inverter-level.
How are PV power generation and meteorological data collected?
The PV power generation data was collected at 5-minute intervals at the inverter-level. The meteorological data was collected at 1-minute intervals from an on-site weather station. The metadata was represented using the Brick schema, which simplifies data comprehension and the development of smart analytics applications.
What are the applications of PV data?
This dataset can be used in various applications - PV generation benchmarking, PV degradation analysis, PV fault detection, solar radiation and PV power generation forecasting, and the simulation and design of PV systems.
Can digital twin model of photovoltaic inverters improve device degradation trend monitoring?
The digital twin model of photovoltaic inverters has achieved good results in the cross experiment of device degradation trend monitoring, indicating that the proposed method is expected to make significant contributions to the simulation, power prediction, and degradation monitoring of grid connected photovoltaic systems. 1. Introduction
How many inverters are in a power station?
It is noteworthy that these 23 stations each contain only one inverter. Consequently, the power generation data measured by the inverter corresponds to inverter-level values. The inverter serves a dual purpose, functioning both as a power converter and as a means of transmitting power generation data.
What happens if a PV inverter fails?
Communication failures between PV inverters and the gateway are typically intermittent and short-lived, often resolving within a few time intervals. Similarly, data logging errors, which occur when the data collection system fails to capture information, also tend to be brief in duration.
