Research On Financial Analysis Of Photovoltaic Power Station Based On System Dynamics

Against the background of intensified energy crisis and environmental pollution,as a promising form of renewable energy,photovoltaic power station has witnessed a series of financial problems such as financing channels,revenue composition and cost control.With the scientific and reasonable methods of financial analysis,it is of great practical significance for the photovoltaic power station to correctly understand the financial dynamic,accurately grasp the direction of financial development and make sustainable financial decisions.The interaction between the internal characteristics and the external environment in the construction,production and operation of photovoltaic power station constitutes a complex system.The change of a single factor will have an impact on the overall financial status and profitability.In view of the shortcomings of the traditional financial analysis methods such as integrality,dynamism and scientificity,based on a comprehensive understanding of the general situation of photovoltaic power station,and the summary of the financial characteristics of photovoltaic power station with heavy assets,no inventory of finished products,fixed costs,and the composition of revenue,relied on the excavation of the key influencing factors in the internal and external environment,this paper applies the theory of system dynamics,divides the complicated system of financial analysis of photovoltaic power station into five subsystems:power supply and demand subsystem,investment and financing subsystem,profit subsystem,cash flow subsystem and asset liability subsystem,and carries out causal feedback analysis and stock flow analysis,systematic and financially-oriented financial analysis model with pertinence and applicability,in order to build a financial analysis model with pertinence and applicability.On this basis,this paper will apply the system dynamics financial analysis model to the typical Z station.According to the actual situation of Z station,this paper establishes the simulation assumptions,revises the model variables,estimates the model parameters,inputs the constant data,presents the nonlinear and dynamic trend of data by the table function,and the validity test and the simulation are completed.Based on the operation results,this paper selects the key factors for financial element analysis,financial ratio analysis and sensitivity analysis,and carries out the financial forecast,then completes analog simulation.Based on the operation results,this paper selects the key factors for financial element analysis,financial ratio analysis and conducts sensitivity analysis,and makes analysis from the aspects of development trend,development capability and sensitivity according to the points of the government and the station.At the same time,it is verified that applying system dynamics to the financial analysis of photovoltaic power station is feasible,which provides a new effective path for the financial analysis of photovoltaic power station.
