Based on the collection and research of big data, this paper analyzes the characteristics of aging assets, analyzes the operating conditions of aging assets from different dimensions, determines optimized investment strategies, and formulates technological transformation and investment plans, which can further improve the accuracy of investment plans. Reasonably allocate operating costs, ensure investment capacity, and maximize the operating benefits of power grid enterprises.
For the comprehensive benefit evaluation of photovoltaic power generation, this paper puts forward a corresponding evaluation model. In order to avoid the influence of human subjective factors, the entropy method is used to modify the weights that determine the relative importance of the indicators at each level of the indicator system by the analytic hierarchy process (AHP). Then, through the matter-element extension model, the comprehensive benefits of photovoltaic power generation projects are comprehensively and systematically analyzed from four aspects: economic benefits, technical benefits, social benefits and environmental benefits. Finally, the comprehensive benefit evaluation of a 30MW photovoltaic power generation project is carried out, and the corresponding conclusions are drawn, which verifies the validity of the model, and provides a method for objectively evaluating the comprehensive benefits of photovoltaic power generation.
Based on the role of photovoltaic power generation (PPG) in solving environmental pollution and resource depletion in the energy sector, this paper studies the investment benefits of PPG. Based on the analysis of the cost and benefit of PPG, the connotation of the environmental benefits of PPG was analyzed, and the investment benefit evaluation model of PPG projects considering environmental benefits was constructed. A case example is analyzed through actual PPG projects. The results show that without considering the environmental value, the net present value of the example project is positive, and the internal rate of return is greater than the capital cost, indicating that the project is economically feasible. After considering the environmental benefits, the net present value of the project has increased by 62.59%, and the internal rate of return has increased by 1.25%, indicating that the investment benefits of the project have been significantly improved after the introduction of environmental benefits.
