Translated Abstract
In recent years, with the strong growth of the photovoltaics market and the implementation of the national leader base plan, the affordable on-grid energy has become the trend of the photovoltaic industry in the future. As a result, the requirements for system efficiency and system solutions become higly required because they have a direct impact on on-grid energy. The way to increase on-grid energy and get more electricity price subsidy is related to the benefits of the project as well as the technological advantages for enterprises to competite projects.
This paper carried out the design scheme selection system of photovoltaic 30MWp (Megabyte Watt Peak) power plants in Yulin City and its light resource utilization conditions are calculated as well as the main factors affecting the power generation were analyzed reasonably.
PVsyst is one of the professional software to study photovoltaic power generation system. The software can calculate the desired system efficiency and on-grid energy by establishing different system models. In this paper, PVsyst simulation software is used to establish Xin Feng Gunag Photovoltaic Power Station model in Yulin’s City. In this paper, the simulation model of Yulin solar photovoltaic power station is established by PVsyst simulation software. For each MW square array, the conversion value of actual power generation is 1398.6MWh, which is 0.0485% lower than that obtained by simulation analysis. At the same time, the error is very small. The accuracy of the simulation model is verified. The paper further analyzes that it can effectively improve the power generation of photovoltaic system by removing dust in time to reduce occlusion and improve operation and maintenance level to reduce the failure rate for the photovoltaic power station. The simulation model verifies that the power generation is 1468.8 MWhs, and the increasing value is about 4.51%.
At last, this paper proposes that many methods can be used, such as selecting the photovoltaic modules and inverters with high conversion efficiency, optimizing the cable laying paths, to improve the system efficiency as well as obtain more economic benefits. In the simulation model, it is verified that the power generation is 1705.9MWh, and the value is increased by 21.38% around.
