摘要：
In order to solve voltage and reactive power control problem in distribution network containing large number of distributed generations, this paper proposes a two-level coordinated control mode in distribution network. The mode contains two control levels. Optimalvoltage of boundary gateway is generated with secondary control system with high voltage distribution networkoptimization; and local reactive power balancing is achieved with primary control system with middle and low voltage distribution networkoptimization.Information interaction between the two control levels is realized with boundary gateway. The two control levels continuously correct voltage and power factor of boundary gateway to achieve global optimization. At last, case simulation is given to prove feasibility and effectiveness of theproposed method. © 2016, Power System Technology Press. All right reserved.
