Adaptive Dispatching Method for Active Distribution Network with Micro-grid Group under Target Cascade Solution
In order to improve the voltage level of active distribution network with micro-grid group,reduce line loss and im-prove the effect of adaptive scheduling,the adaptive scheduling method of active distribution network with micro-grid group un-der target cascade solution is studied.The adaptive dispatching of active distribution network with micro-grid group is divided into two parts:reactive power dispatching with network loss optimization and active power dispatching with power optimiza-tion.The reactive power dispatching method of network loss optimization aims at minimizing the network loss of microgrid,and mainly optimizes the reactive power of distributed generation and the reactive interaction power between micro-grid and ac-tive distribution network.The power optimization active power scheduling method aims to achieve power balance within the distribution network by adjusting the active power output of distributed power sources,exchanging active power between mi-cro-grid and active distribution network,and purchasing electricity from higher-level power grids.In this paper,the goal casca-ding analysis method is used to analyze the difference between the objective functions,and the micro-grid scheduling model and the active distribution network scheduling model are solved in parallel to realize the adaptive scheduling of the active distribution network with micro-grid groups.The test results show that this method can improve the local voltage level of active distribu-tion network to 0.937 pu.The line loss power is reduced to 0.23 MW and has good convergence,which improves the adaptive dispatching effect of distribution network.
