[Abstract]:With the layout of the 13th Five-Year Plan, China's economy is developing steadily, and the demand for electricity energy is also increasing in an orderly manner. However, the distribution of the national energy structure is uneven, and there is a great difference in the power load in the eastern and western regions. As a result, the investment in the eastern and western regions is uneven, the power grid scale is different, and the power grid investment pressure is great in the western region. In recent years, with the large-scale development of new energy represented by photovoltaic wind energy, the grid-connected operation of large-scale new energy has an impact on the stability and security of large power grid operation. However, because of its economic, environmental protection, it can meet the diverse power quality needs of users, solve the problem of power load demand in remote areas, alleviate the investment pressure of large power grid, and give full play to the value and benefit of distributed generation. It can be used as a useful supplement to large power grid, and has solved many potential problems of large-scale power system, and has been paid more and more attention by the power industry. In order to meet the national strategic requirements of Inner Mongolia Autonomous region Alashan Zuo Banner Erke Hashha Sumu construction networking new energy microgrid demonstration project to further speed up the new energy microgrid strategic investment layout. The new energy microgrid project, with its cleanliness and stability, can effectively solve the advantages of power supply demand in remote areas and alleviate the pressure of large electricity investment in Erke Hashha area. However, due to the complexity of the new energy microgrid project, it is difficult to realize the evaluation and quantification of the economic benefits of the new energy micro-grid, and can not effectively quantify the benefits of the micro-grid to the users, the power sector and the society. Carry out reasonable scheme selection. In this paper, the micro-grid theory and new energy micro-grid engineering cost-benefit theory combed, at the same time, the new energy micro-grid investment environment in Erke Hasha area, Alashan, Inner Mongolia, demonstrated the feasibility of the project implementation; Then through the research parameter collection carries on the cost benefit calculation, quantifies the project investment cost benefit; Finally, a new energy microgrid project cost-benefit quantitative measurement model and grey relational degree comprehensive evaluation model based on TOPSIS are put forward in this paper. Through this method, the investment scheme of new energy microgrid in Erke Hashha area is scientifically compared and evaluated, and the cost benefit calculation method of new energy microgrid project is defined, which provides the basis for project investment decision and scheme election.
