Research on the Investments Allocation of Comprehensive Plan of Power Grid Enterprises under the Electricity Transmission and Distribution Price Reformation

The reform of the transmission and distribution price affects the allocation of comprehensive investment plan of power grid enterprises, so it is necessary to combine the historical data and experts' experience to study the investment allocation strategy with different development objectives. Based on the practical background, we established the system dynamics model to analyze the relationships between different variables. It can make simulations to calculate the investment in professional sectors under the condition that the transmission and distribution price remains stable. In addition, by changing the relevant variables of the model, we can compare the investments of professional departments in different scenarios. The method can provide decision-making support for enterprises. At last, a numerical example is used to illustrate the method.
