Embodiment Construction
[0046] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0047] Such as figure 2 , is the flow chart of cost-benefit evaluation of distributed photovoltaic power theft based on B / C method. The function of the present invention is mainly based on the distributed photovoltaic power theft, firstly determine the installed capacity of the photovoltaic power station; then estimate the annual power generation of the distributed photovoltaic power station; then estimate the total load and spatial load distribution. Analyze typical photovoltaic stealing methods; list alternative photovoltaic stealing operation modes. And analyze three typical photovoltaic stealing methods and two photovoltaic stealing operation modes. Clarify the boundary conditions and calculation parameters under different photovoltaic stealing operation modes. Calculate the initial investment cost of photovoltaic power stealing equi...

The invention discloses a method for establishing a distributed photovoltaic power stealing cost benefit evaluation model based on a B / C (Benefit / Cost) method. The distributed photovoltaic power stealing cost benefit evaluation model based on a B / C method comprises: determining the installed capacity of a distributed photovoltaic power station according to the construction situation of the distributed photovoltaic power station; combined with the installed capacity, the environmental conditions and the generating capacity in former years, estimating the annual generating capacity of the distributed photovoltaic power station; analyzing the equipment composition and the operational mode of different photovoltaic power stealing methods; calculating the cost composition of photovoltaic power stealing under different power stealing operation modes, and establishing a life cycle total cost model under different photovoltaic power stealing operation modes; calculating the power sealing total income of photovoltaic power generation under different power stealing operation modes; and at last establishing a benefit ratio model under different power stealing operation modes. Through the models established through the above method, the profit situation can be calculated under different power sealing modes and different power sealing operation modes, and the power sealing mode which appears with higher possibility can be speculated so as to provide a basis for development and operation of power sealing identification technology for the power sealing mode.
Description
technical field [0001] The invention relates to a B / C method-based distributed photovoltaic stealing cost-benefit evaluation method, which belongs to the technical field of photovoltaic anti-stealing. Background technique [0002] Photovoltaic power generation is an important means to deal with the fossil energy crisis and environmental problems. With the increase of my country's photovoltaic power generation subsidies, my country's distributed photovoltaic power generation has increased sharply. Since the income obtained by users depends on the amount of photovoltaic power generation, there may be photovoltaic power theft behaviors in which users use technical means to make photovoltaic power generation meters measure more power generation. Photovoltaic electricity theft will not only disrupt the photovoltaic power generation market and cause financial losses to the country, but also bring huge security risks to the power grid due to users' unauthorized wiring changes. ...
