【摘要】：随着国家“十三五”规划布局,我国经济呈现稳定发展,人们对电力能源的需求也有序增长,然而国家能源结构分布不均,东西部地区电力负荷存在较大的差别,导致东西部地区电网投资不均,电网规模差异较大,西部地区电网投资压力较大。在近年大规模发展以光伏风能为代表的新能源大力发展,大规模新能源的并网运行对大电网运行的稳定性和安全性产生影响。然而微电网以其经济、环保、能满足用户多样化电能质量需求等特点,解决边远地区电力负荷需求问题,缓解大电网投资压力,充分发挥了分布式发电的价值和效益,可作为大型主电网的有益补充,解决了大规模电力系统的诸多潜在问题,受到了电力行业越来越多的关注。为迎合国家战略要求内蒙自治区阿拉善左旗额尔克哈什哈苏木建设联网型新能源微电网示范项目,进一步加快新能源微电网战略投资布局。新能源微电网工程项目,凭借其清洁,稳定,可以有效解决边远地区供电需求的优点,减缓额尔克哈什哈地区大电投资压力。然而由于新能源微电网工程项目的复杂性,难以实现新能源微电网的经济效益评估和量化,无法有效的将微电网对用户、电力部门及社会的效益全面量化,进行合理的方案选优。本文在进行微电网理论研究以及新能源微电网工程成本效益理论梳理的同时;对内蒙阿拉善左旗额尔克哈什哈地区新能源微电网投资环境进行具体分析时,论证项目实施可行;再通过调研参数收集进行成本效益测算,量化项目投资成本效益;最后本文提出的新能源微电网项目成本效益定量测算模型以及基于TOPSIS的灰色关联度综合评价模型,通过此方法对额尔克哈什哈地区新能源微电网投资方案进行科学的综合比选评价,明确了新能源微电网工程项目成本效益测算方法,为项目投资决策及方案选举提供依据。
[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.
