Distributed Optimal Dispatch of Active Distribution Network Considering Carbon-electricity Trading

To promote the low-carbon and economic operation of the distribution network, introducing the carbon trading mechanism into the active distribution network dispatch plays a positive role in achieving carbon reduction. Therefore, a distributed optimal dispatching model considering carbon-electricity trading is established. First, the carbon transaction cost calculation method is defined on the supply side, and electric vehicles on the demand side are granted carbon quotas to obtain benefits, so as to exploiting the carbon reduction potential on both sides of the power grid supply and demand. Based on this, a large number of distributed energy sources in active distribution network are researched to participate in the frequency regulation auxiliary service market and carbon trading market, and an integrated carbon-electricity trading framework is constructed. An active distribution network low-carbon economic optimization dispatch model is established, and a consensus algorithm is applied to solve. The impact of carbon trading price and frequency modulation reserve ratio coefficient on dispatching results are analyzed by simulation, and the proposed dispatching method is proved to be able to achieve low-carbon and economic optimization operation.
