increase the interests of virtual power plants (VPPs)
and reduce carbon emissions
a collaborative optimal dispatch method for multi-VPPs considering low-carbon goals and a master-slave game was proposed. First
the power-heat collaborative game optimization framework for multi-VPPs was constructed. The distribution system operator (DSO) was introduced as the leader
which formulated energy trading prices according to the dispatch strategies of VPPs. VPPs were regarded as followers
which developed energy dispatch and electricity purchase-sales strategies based on the trading prices
thus forming a mutual game relationship between the two parties. Then
a stepped carbon trading mechanism and a dual-compensation demand response were incorporated to further explore the low-carbon potential of the master-slave game. Finally
the optimal dispatch mathematical models for DSO and VPPs were developed
and the particle swarm optimization (PSO) algorithm combined with mixed-integer nonlinear programming (MINLP) was adopted for solution. Four scenarios were set up for comparative analysis. Results show that the proposed game model can promote multi-energy collaborative complementarity among multi-VPPs while maximizing the interests of each VPP. Owing to the increased energy interaction between VPPs and the integration of the stepped carbon trading mechanism
the model can effectively reduce carbon emissions. Meanwhile
the dual-compensation demand response can guide load curtailment and improve low-carbon efficiency.
