Comprehensive evaluation method for distributed power generating project

Abstract

The invention provides a comprehensive evaluation method for a distributed power generating project. The influences of operation modes of different operation entities of the distributed power generating project, a synchronization technical scheme and income from investment under a complex electricity price system, the cost factors, such as initial investment, running maintenance and investment recovery period, on the comprehensive evaluation for the distributed power generating project are comprehensively considered; a ratio of income to cost is used for evaluating the feasibility of the project; and an optimal operation mode is selected. According to the comprehensive evaluation method provided by the invention, the rough defect of the traditional comprehensive evaluation method for the distributed power generating project is overcome; the income and the cost of the project in the life cycle are considered; a meticulous and comprehensive thought is adopted; the cost allocation of the complex electric price system and benefit parties is considered; the operation modes of different operation entities are combined; the distributed power generating project is comprehensively evaluated and the optimal scheme is selected; and an empirical analysis result proves that the method is effective and accurate in the comprehensive evaluation of the distributed power generating project.

Description

technical field [0001] The invention relates to the fields of power systems and new energy sources, in particular to a comprehensive evaluation method for distributed power generation projects. Background technique [0002] In the past year, China's distributed power generation projects have developed from external cold and internal heat, technological innovation and promotion of incentive policies have basically formed a stable technical and industrial system in China's distributed power generation system, and the power generation system is setting capacity has also developed rapidly. [0003] Although these projects have made bold attempts and breakthroughs in clean energy utilization and energy-saving methods, the comprehensive evaluation and optimization methods of the entire project are the most concerned by investors and difficult to predict, and investors and operators under different business models are different. The investment income of the main body is closely re...

Problems solved by technology

[0003] Although these projects have made bold attempts and breakthroughs in clean energy utilization and energy-saving methods, the comprehensive evaluation and optimization methods of the entire project are the most concerned by investors and difficult to predict, and investors and operators under different business models are different. The investment income of the main body is closely related to the grid-connected technology and the electricity price mechanism, and the calculation is very complicated. There has been no relevant in-depth systematic research before

In the economic evaluation of projects, investors have been using relatively rough calculation methods, resulting in inaccurate predictions. Many projects suffer serious losses after operation, and they have not used the project's entire life cycle (Life Cycle Cost (LCC), also known as life cycle cost). Cycle cost is an evaluation and calculation method for the government or project to set up and obtain the system and the total cost consumed by the system in its lifetime). At the same time, previous research focused on the research of power generation costs, but did not include the return on investment of electricity costs into investment decisions Important Metrics to Consider
