Abstract: The responsibility weight system for renewable energy accommodation and the construction of power spot market are being implemented simultaneously in China. In order to coordinate the relationship between the conventional power trading varieties and the accommodation responsibility weight trading varieties and to realize the smooth implementation of the accommodation weight system, we designed a market mechanism of renewable energy accommodation weight under the spot market environment. Based on an analysis of the difficulties in implementation of the accommodation weight system under the background of spot market, relevant market mechanisms are designed from four aspects, including main market players, transaction varieties, transaction mode and cycle, and transaction process. A market design of power grid player-included excessive accommodation is innovatively put forward. A case study demonstrates the positive significance of the power grid player-included excessive accommodation market in promoting the development of new energy.
