Title    The Research of the recognition methods about  raising current to steal photovoltaic electricity
Abstract
Extensive use and shortages of fossil fuels make energy and environmental problems becoming increasingly prominent. The use of solar and other clean and renewable
energy is bound to become the main trend in the 21st century. The main use of
solar energy is converting it to electricity which can be connected to grid. National high subsidies for PV lead to the behavior which criminals use photovoltaic stealing methods to cheat the subsidy of national electrovalence. Traditional identification for stealing electricity cannot be used on photovoltaic stealing recognition . Therefore, the main contents of this thesis which is aimed at raising current to steal electricity and the research of the recognition methods include: 源`自*六)维[论*文'网www.lwfree.cn
Ⅰ. This Grid-connected PV system is developed using SIMULINK of the MATLAB.
Ⅱ. The model of raising current to steal electricity is built on the basis of
the grid-connected PV system.
Ⅲ. The circuit can be accurately identified whether stealing electricity by
obtaining a lot of data through simulation by changing environmental factors
and using a mathematical model to analyze and process them.
