Simulation Research On Rural Distributed New Energy Power Grid Based On Internet Of Things

With the increase of energy and environmental problems,new energy generation technology is attracted by more and more scholars and technologists.With the popularization and application of the Internet of things technology,the information network and the Internet of things have promoted the development of smart power grid and smart grid.In rural areas,remote areas,they still have the following main problems of electric power construction and power grid development:1)Limited by traditional energy(conventional energy)supply,from the power supply to the load side,The construction of power grid has a large span,long distance and high loss of line;2)Due to the environmental and climate impacts,the power grid needs higher tolerance to increase the service life;3)The load side is decentralized and the operator's technology is low,the fault monitoring and elimination are all restricted,and the damage of personnel is easy to be caused;4)The surplus power cannot be connected to the net in time,which can easily lead to waste of resources;5)The grid-connected technology of the micro grid needs to be improved,which increases the maintenance difficulty and cost accounting of the equipment to a certain extent.The above problems can be solved through sensor technology,cloud computing and big data technology,high-speed information transmission network,accurate control technology and the formation of a new power grid.In particular,solar power generation,wind power generation,biomass energy generation and grid connection technology have demonstrated strong demand for Internet of things technology.In this paper,on the basis of the existing new energy power generation technology,explore and electricity to meet the bad environment in the countryside area "use local materials" method for power generation,power transmission to the electricity.This paper studies the new energy technology is relatively mature solar photovoltaic power generation,wind power and biomass power generation technology is more suitable for rural,and the power of the system and the grid situation.The main research work is as follows:(1)This paper studies the energy use in our country,especially in the consumption of electrical energy,rural electricity consumption,new energy construction target,etc,in rural and remote areas is analyzed on the necessity and the possibility of the construction of new energy power generation.For micro power grid and the Internet of things technology development status at home and abroad were reviewed,especially the distributed power grid and the combination of the Internet of things technology emphatically studied,put forward the rural construction in our country new energy assisted with the Internet of things technology micro power grid is proposed.(2)On the basis of the research on new energy,solar energy,wind energy and biomass can be selected as the main rural energy sources,and the working principle and application status of the three energy sources are analyzed.The overall framework and key technologies of iot technology are analyzed and studied,and the application of iot technology in power grid and new energy generation is found to be a combination point.(3)By using PSCAD software,to solar,wind,biomass energy grid technologies are simulated,and the distribution of weak power grid were discussed,for the application of new energy power generation in rural areas for technical analysis and systemic design,and the paper analyzes and discusses the possible impact.(4)In view of the possible parallel network problems mentioned above,the application of Internet of things technology is proposed and the simulation research is carried out.Among them,with the effect of solar wind power monitoring and control technology on a daily basis,tiny system monitoring of Internet layer structures,biomass power generation and gas control is given priority to,have put forward the corresponding solutions.In the case of the Internet of things in solar greenhouse,the software platform is built and designed.(5)Finally,based on the actual construction data of rural power grid,the mathematical model of light,wind,diesel(on behalf of biomass energy)and dc energy storage system is established,and the PSCAD software is used for simulation.lt provides theoretical and simulation research reference for the development of "wisdom" of rural power grid in the new energy.
