Research on Low-Carbon Economic Dispatch of Active Distribution Network Considering V2G and Demand Response

Abstract

With the increasing penetration of distributed renewable energy and flexible loads in the distribution network, the traditional distribution network is gradually transitioning to an active distribution network. Due to the vigorous development of new power system, the economic dispatch of active distribution network faces great challenges. Therefore, this paper introduces V2G technology while considering the carbon emission of the system, establishes an orderly charging and discharging model for electric vehicles and then builds demand response modeling based on transferable load and interruptible load, and then conducts second-order cone relaxation on the branch power flow constraints of the distribution network. Finally, With the goal of minimizing the dispatch cost for active distribution network, this paper proposes a low-carbon economic dispatch model for active distribution network considering V2G and demand response. The Case studies of IEEE 33-node power distribution system verifies that the proposed model can effectively reduce the dispatch cost, enhance the security of system operation and reduce carbon emission.
