The aim of regional electricity market construction is to allocate the resources in the more extensive region by market measures. It should be propitious to promote the persistent and harmonious development of each province's economy and electrical industry, and to hedge the market risk as well. Contemporarily, it should consider the cooperation between the regional and provincial (civic) power grid, the interest balance and coordination among every side, the resource allocation equity, the secure and stable operation of power grid, and effective coordination between market transaction and power grid dispatch. Based on the above rule, the transaction mechanism of regional layered electricity market is analyzed, and several regional layered electricity market modes and transaction mechanism are designed, which harmonize power grids security and market exchanges. Furthermore, the advantages and disadvantages of each mode are analyzed, and the realization conditions of each mode are set. At last, several intergradations from regional layered electricity market to regional uniform electricity market are presented.
