With the rapid growth of renewable energy installed capacity in China, the accommodation task becomes more difficult. The construction of electricity markets also needs to combine the characteristics of the power grid development and find a market mode in the background of high proportional of renewable energy. Based on the analysis of the problems existing in the current operation mechanism of the two-level peak regulation auxiliary service market in Northwest China, this paper proposes the key problems and their solutions in the coordination operation of inter- and intra-provincial electricity markets in the future regional power grid. And an inter-market optimization coordination mechanism aiming at maximizing the accommodation of renewable energy is established. The designed mechanism can promote the orderly cooperation of multiple inter- and intra-provincial markets, and also promote the optimal allocation of electric energy and the effective use of peak regulation resources. Based on the actual operation data of a provincial electricity market, the simulation calculation and the comparative analysis of the proposed two-level market coordination mechanism are conducted, and the results verify the effectiveness of the designed mechanism.
