Study Of The Impact Of Distributed Photovoltaic On The Voltage And Power Loss Of XX Distribution Network

With the environmental pollution and the exhaust of the fossil fuel,the photovoltaic is developing rapidly for the advantages of easy installation,no noisy,sustainable and so on.The decrease of the productive cost of the photovoltaic accelerates the development of the photovoltaic.The prominent characteristics of the photovoltaic are randomness,variant and uncontrollability for the impact of the weather.Consequently,the impact of the photovoltaic on the voltage profile,power loss and so on is more and more obvious when the penetration of the photovoltaic is high.Hence,this paper studied the impact of the photovoltaic on the voltage profile and power loss of power system based on the parameters of the real network.The main contents of this paper are listed as below.Firstly,the basic principle,research status and key technologies of the photovoltaic system are studied by looking up the related documents at home and abroad.The main types of the photovoltaic are summarized.Then,the existing problems of the above research are given.Furthermore,the impact of photovoltaic on the power system is introduced.Then,the basic principle of the load flow of power system is introduced.The calculation methods of the distribution system are given.The photovoltaic in the distribution network is introduced with the real power grid.The impact of the photovoltaic on the voltage profile of the distribution system under different scenarios is studied.The comparison of the voltage profile of the distribution network with and without photovoltaic is performed.Finally,the impact of the photovoltaic on the voltage and power loss of the distribution system with multi scenarios is studied.The impact of the multi photovoltaic on the voltage profile of the distribution system under each scenario is calculated.Thus,the law of the impact of photovoltaic on the distribution system is given.
