Distributed Optimization of Flexible Interconnected AC/DC Distribution System Based on Soft Open Point
The optimal dispatch problem of flexible interconnected AC/DC distribution systems is studied. By introducing flexible interconnected devices combining soft open point (SOP) and DC charging devices at the boundary of the distribution network
an improved multi-regional and multi-objective distributed optimization model of flexible interconnected distribution systems is established
which takes into account various distributed resources. Through the establishment of boundary and SOP decoupling models
the system optimization is divided into several sub-problems
including microgrid sub-region optimization
distribution network sub-region optimization
microgrid and distribution network partition boundary optimization
and flexible interconnected device optimization. For protecting the privacy of each region
the dispatch scheme in which each region
partition boundary and SOP participate in distributed optimization is proposed. Furthermore
the adaptive step size adjustment mechanism for the alternating direction method of multipliers is adopted to improve the computing efficiency. Finally
the effectiveness and expansibility of the algorithm and the economy of the flexible interconnected model are verified by simulation.
