Abstract
The new round of power system reform has strengthened the supervision of transmission and distribution links, and changed the profit model of power grid enterprises by verifying the transmission and distribution price. In this context, the research on the regulatory risk faced by power grid enterprises under the electricity price regulatory policy can provide tools and decision support for power grid enterprises to accurately grasp the regulatory risk and reduce the risk loss. Firstly, combined with the transmission and distribution price supervision process faced by power grid enterprises, the possible risks faced by power grid enterprises in price supervision are analyzed. Secondly, the quantitative measurement model of electricity price regulation of power grid enterprises is constructed by using system dynamics, and the effectiveness of the model is verified. Finally, the future regulatory period is simulated and the results are analyzed, and policy recommendations are put forward.
Highlights
China’s transmission and distribution (T&D) electricity price reform has gradually moved towards strong supervision
The quantitative measurement model of electricity price supervision risk of power grid enterprises based on system dynamics mainly includes four subsystems: transmission and distribution effective assets subsystem, transmission and distribution permitted cost subsystem, electricity price approval subsystem and operation effect subsystem
4.2 Empirical analysis and results According to the basic information of the example, the system dynamics is used to simulate the model, and the income, cost and profit, R&D investment, asset operation and maintenance investment and profitability are used as the index to judge the risk of electricity price regulation, as shown in figure 2
Summary
China’s transmission and distribution (T&D) electricity price reform has gradually moved towards strong supervision. The government's supervision on power grid enterprises is increasingly focused on the T&D electricity price. Et al pointed out that the reform of T&D fee limits the income of China's grid companies and increases the operating pressure[2]. Et al analysed the investment decision of power grid under the reform of transmission and distribution electricity price, proposed the estimation model of power grid investment demand and the measurement model of power grid enterprise investment capacity, and constructed the optimization model of power grid investment scale[3]. System dynamics (SD) analyzes the structure and function of the whole system It can observe the changes of the whole system by changing the parameters in the system, so as to find the best way to solve the system problems. Et al established the financial capability model of power grid company by using system dynamics theory[6]. The pricing process and execution process of T&D price regulation is a complex system, so the regulatory risk faced by power enterprises can be applied to the system dynamics model
