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.
