Composite carbon emission limit sharing demand response adjustment method and system

The invention discloses a demand response adjustment method for composite carbon emission limit sharing, and the method comprises the steps: constructing a countercurrent distribution matrix considering the network loss and a power generation node carbon flow injection column vector based on a carbon emission flow theory through employing a node carbon intensity evaluation method, calculating a carbon emission quota result of the system and node carbon footprint intensity of the network in combination with the power flow result; referring to historical data, a distribution theory and node related data, introducing a balance interval concept suitable for a power system, and forming a carbon limit constraint interval; and establishing a demand response low-carbon regulation cost minimization model based on carbon limit recheck allocation, considering carbon constraint and load regulation capability in related nodes, solving an optimal value by using a particle swarm algorithm, and verifying the optimal solution
