Research and Demonstration of Planning and Decision-making Tools Based on Power Grid Full -Cost Chain

It is urgent to change the development mode of power grid enterprises, comply with the development trend of the new round of power system reform, and plan ahead to carry out research on new models, new models and new methods of investment planning decisions in the market environment, and promote the improvement of transmission and distribution network planning. Scientific and effective, comprehensively improve the level of optimal allocation of power resources. First of all, this paper studies the calculation method of full-cost chain and full-cost node electricity price. Then, the functional module of planning decision tool based on the full cost chain of the power grid is proposed. Finally, the selected project is determined based on the sensitivity of the investment ceiling.
