Study on Optimal Strategy of Investment Decision of Power Supply Company based on System Dynamics

Power supply industry is the basic industry that affects the development of national economy. The operation development and reform trend of power supply enterprises has been highly concerned by the society. With the proposal of No. 9, the process of electric power system reform has been further deepened, and the requirements of power supply enterprises on the scientific and accuracy of investment decision-making have been continuously improved. This paper identifies and analyzes the important indexes of the power supply enterprises in the investment decision and operation process, and screens out the business indexes closely related to the investment decisions of the power supply enterprises. Taking the important business indexes as constraints, the optimization model of the investment decisions of the power supply enterprises is constructed by adopting the idea and method of system dynamics. Taking the operational parameters of a local power supply enterprise in a southern province of China as an example, the optimal investment scale of power supply enterprises under the constraint of business objectives is calculated, providing a reference basis for the investment decision of enterprises, giving priority to the optimal allocation of resources, and promoting the healthy and sustainable development of power supply enterprises.
