Abstract
This paper introduces an innovative method for forecasting investments in power grid technical renovation projects. By employing the Angle of Inclination Correlation and an Enhanced Gray Model, our goal is to enhance investment prediction accuracy in the electric power industry. Using data from 2016-2021, we select key indicators, such as maximum grid load, power supply capacity, line length renovations, electricity sales revenue, installed capacity, line loss rate, unit substation capacity cost, and power supply reliability, to evaluate their impact on technical renovation projects. The Improved Gray Model is then used to forecast 2022 investments. Subsequently, a Markov model is applied to refine predictions and calculate the deviation rate, confirming the method's effectiveness in indicator selection. While this approach holds promise, it is essential to acknowledge the limitations of historical data, which do not meet big data requirements.
