Title: Study on calculating the PV system size of a fifteen kilowatt (HP) agricultural diesel generator set in a grid-connected inverter PV system with a PV option of 10 kW
I. Introduction
In recent years, with the rapid development of photovoltaic technology and the country's emphasis and support for new energy, more and more rural areas and enterprises have begun to pay attention to the construction of solar photovoltaic power generation systems. The purpose of this paper is to discuss how to reasonably calculate and select the appropriate PV system size given specific requirements, especially the PV system size calculation problem with 15 kilowatt (HP) agricultural diesel generator sets as auxiliary energy source. In this case, the target system size of 10 kW will be used as a reference standard.
2. Background analysis
Sizing a PV system involves a number of factors, including geographical location, climatic conditions, load demand, and grid capacity. Especially in remote areas or agricultural fields, diesel generator sets are often used as backup power or emergency power supply. Therefore, when calculating the size of a photovoltaic system, the power and efficiency of diesel generators need to be considered. In this case, the calculation is based on a 15 kW agricultural diesel generator set and connected to the photovoltaic system for joint power supply. At the same time, the reverse power conversion device is used to achieve the optimal working mode conversion that matches the system. In this regard, it is necessary to conduct a comprehensive investigation and analysis of the actual requirements and scenario characteristics.
3. Discussion of calculation methods
When calculating the size of a PV system, the first step is to determine the load demand and load characteristics. For agricultural use, the load mainly includes irrigation equipment, agricultural machinery and equipment, etc. Based on the load demand analysis, the total power demand for each day is calculated. Then, combined with local light conditions and solar radiation data, the amount of solar power that can be used per day is calculated. Finally, the required PV system size is determined according to the balance between load demand and solar power generation. In addition, the configuration of the energy storage system and the optimization of the battery management system need to be considered. Due to the grid-connected operation of diesel generator sets, it is also necessary to select and configure the grid-connected inverter to ensure the stable operation and efficient conversion efficiency of the system. Therefore, the whole calculation process is complex and requires a combination of factors.
Fourth, case analysis
Assuming that the target area has an average daily solar radiation of X hours/day and a load demand of fifteen kilowatt hours (kWh), the amount of electricity that can be provided by the solar PV system should meet the load demand. Considering that diesel generator sets can provide additional power support as a backup power source, their capacity requirements can be appropriately reduced when calculating the size of a PV system. After comprehensively considering the light conditions, load characteristics, and performance parameters of the diesel generator, the scale of the 10 kW photovoltaic system was finally determined. At this scale, the synergy between photovoltaic and diesel generators can be realized, which can not only meet the daily load demand, but also make full use of solar energy resources to achieve the purpose of energy conservation and emission reduction. At the same time, the reasonable configuration of the grid-connected inverter also ensures the stable operation of the system and the realization of efficient conversion efficiency. 5. Conclusions: Through the above analysis and calculation, it can be seen that it is feasible to reasonably select the scale of a 10 kW photovoltaic system under the premise of meeting the load demand and light conditions. In actual operation, it is also necessary to make appropriate adjustments and optimizations according to the specific situation to ensure the stable operation of the system and the realization of efficient performance. At the same time, with the continuous progress of technology and the continuous growth of market demand, the configuration scheme of photovoltaic system will be continuously updated and optimized to achieve a more economical and environmentally friendly power supply scheme, serve the needs of society and people, and have great development space, and have broad prospects for future applications.

Future prospects: With the continuous progress of new energy technology and the continuous support of national policies, the application of photovoltaic systems in the future will be more extensive and deeper, especially in the field of agriculture, and the application will be greatly expanded and developed. In the future, with the continuous improvement of photovoltaic module efficiency and energy storage technology, as well as the application of intelligent management and control technology, the configuration scheme of photovoltaic system will be more flexible and diverse, which can adapt to various complex environments and load needs, achieve more economical and environmentally friendly power supply solutions, and provide more reliable power guarantee for the development of rural areas and society.
