Green Power Market Space Prediction and Evaluation Model Based on Interconnected Power Grid Interconnection

Abstract

The interconnection of power grid plays as the key role in the B&R strategy, which has great significance in achieving optimal allocation of energy resources. Aiming at the characteristics of the power interconnection “dominated by the transmission of clean energy”, this paper proposes a forecasting and assessing model for the green power market space. Firstly, the traditional electricity market space is expanded, and a concept of “green power market space” is proposed, which is suitable for the B&R power interconnection power flow planning. Then, an assessing model of optimal renewable energy uptake scale of regional grid is established from the physical and mathematical levels. To fully reflect the complexity and difficulty of power interconnection system, a new combination weighting approach consists both of fuzzy-logarithmic and anti-entropy methods is adopted, meanwhile fuzzy membership concept is introduced into overall evaluation for B&R regional grid power structure.
