摘要：
In order to deal with complex situation caused by element change in power system, it is necessary to synergistically optimize source and network. Therefore, concept of conflict degree between source and network is proposed in this paper to give a quantitative evaluation of power grid restriction to source operation. On this basis, in order to minimize power grid structure change to ease conflict between source and network, a two level optimization formulation of this problem are proposed. Taking operation states of transmission elements as decision variables, the upper level problem is to minimize power grid structure change to maintain conflict degree between source and network within acceptable range. Under the power grid structure determined by the upper level problem, the lower level problem optimizes generation unit operation. The model is a mixed-integer linear two level optimization model and can be converted to a mixed-integer linear single level optimization model with KKT condition in the lower level problem. Finally, significance of this study is illustrated with 5-bus and 30-bus systems. © 2016, Power System Technology Press. All right reserved.
