Abstract

Abstract:

Aiming at the key issues such as energy and electricity cost dredging and unbalanced cost allocation in the bilateral power market under the double-track system in China, the dual settlement system of "day-ahead benchmark, real-time difference, and contract price difference" is used to realize the coupling settlement between the contract market and the spot market, and the construction of the responsible entity is considered. The unbalanced capital apportionment/return model and the bilateral spot market settlement mechanism considering the unbalanced capital processing is designed, and the simulation analysis is carried out with the power market of Zhejiang Province. The calculation example proves the rationality of the settlement mechanism. An effective electricity bill settlement system can improve the enthusiasm of the generators to participate in the electricity market, and provide relevant reference suggestions for the settlement of bilateral electricity markets under the double-track system.
