Based on the preliminary introduction of power demand response, this paper puts forward the problem in multi-level demand response reliable communication. Next, we analysis the principle of block chain technology, and then according to the characteristics of power demand response, the private block chain is chosen to solve the problem of mutual trust between users, load aggregators and power grids in multi-level demand response reliable communication. Smart contracts are used to solve the problem of demand response automation.
