6. Input data models6.1. PV energy The solar power production profiles in this study are based on historical data of global irradiance of real sky (W/m 2) on a fixed and sloped plane collected from PVGIS (Photovoltaic Geographical Information System) [61] for a period of 24 h in the following locations where the EV workplace charging station sizing study is
The number of large photovoltaic (PV) power plants is increasing around the world. Energy sale usually follows demand contracts with clearly defined obligations, subject to nonsupply penalties.
Hydrogen energy plays a crucial role in driving energy transformation within the framework of the dual-carbon target. Nevertheless, the production cost of hydrogen through electrolysis of water remains high, and the average power consumption of hydrogen production per unit is 55.6kwh/kg, and the electricity demand is large. At the same time, transporting
The operation and maintenance costs of energy storage systems are mainly composed of three parts: energy storage construction cost, maintenance cost, and energy storage benefit. Among them, the energy storage benefits include the environmental benefits brought by the energy storage connected to the distribution
3.2 Photovoltaic power station operation and maintenance data collection. The photovoltaic power station studied in this paper has an onl ine power output of 5.5421 million. kWh from January to
3.1. Digital construction of equipment monitoring. The monitoring system of the power station consists of three levels: dispatching analysis layer, monitoring layer and equipment layer. Dispatching analysis layer is the superior dispatching center and a bridge between the power generation system. On the one hand, it builds open consistent grid
As part of PPAPS′ O&M performance, the role of the O&M contracts has yet to be proven. This paper uses a three-stage data envelopment analysis (DEA) model and grey relation analysis (GRA) to analyze the O&M performance efficiency of PPAPS and the influencing factors of contract governance from field data of 110 counties in Henan Province, China.
If there is still remaining PV power after the energy storage is fully charged, it is considered as the discarded solar PV. The annual operation and maintenance cost of energy storage is 0.5 % of the initial investment. The residual value rate of fixed assets is 5.
First of all, the operation and maintenance of photovoltaic power stations can ensure long-term stable power generation. A photovoltaic power station consists of photovoltaic modules, inverters
