“…In general, from the transmission perspective, the distribution is usually regarded as load injections at boundary busses. Conversely, from the distribution perspective, transmission is usually regarded as a virtual source generating at the nodal price . Meanwhile, the power values and nodal price at the boundary busses can be mutually observable .…”

Summary The separation scheduling of transmission and distribution (T&D) grids brings unbalanced boundary power and insufficient utilization of grid resources in practice. To solve these problems, a dynamic coordinated scheduling scheme for an integrated T&D framework is developed in this paper. Taking into consideration the operating characteristics of the integrated system, a two‐stage optimization model is proposed considering the shared variables between the T&D grids. The model contains two submodels, which have their own scheduling objectives. Besides, in order to reflect the output characteristics of renewable energy generations (REGs), robust optimization approach is introduced to deal with uncertainties of outputs. To solve this model, a hierarchical optimization algorithm is presented. The algorithm ensures interaction process between the T&D grids and can coordinate the relationship between system economy and robustness effectively. Finally, the case studies verify efficiency of the proposed scheduling scheme.

“…Power flow calculation is a significant tool in power system planning and operational studies . With the increasing number of DRGs, several novel power flow calculations have been extensively studied by researchers, and a series of surveys have been reported particularly on the subject of Newton‐iterative method .

Summary This paper analyzes the equivalent impedance characteristics of the ac microgrid with distributed renewable energy generations (DRGs) based on the droop control and proposes a decoupled power flow calculation method. The droop control strategy with adaptive virtual impedance has become an effective solution to utilize the DRG. To analyze the characteristics of the DRG, a microgrid consisting of multi‐DRGs based on distributed consensus‐based secondary voltage droop control with adaptive virtual impedance is researched. Considering the characteristics of the DRGs, a decoupled power flow calculation can be proposed to satisfy the quick power flow calculation in order to achieve economic dispatch and stability recovery for the microgrid. Furthermore, the accuracy of the power flow calculation with considering virtual impedance is improved. Moreover, a small microgrid, including three DRGs, has been modeled and simulated using the MATLAB/Simulink. Eventually, the decoupled power flow calculation is tested on three test case systems.

Abstract.For the large-scale integration of renewable generation into power grid and strengthening of active load regulation ability, the power transmission and distribution network coupling has become closer, and the contradiction between the source and network has been more prominent, which has brought new challenges to power system operation dispatching. In order to further enhance the coordination and interaction ability of the power grid, a synergistic dispatching model of power source and electric network is constructed on the basis of the traditional economic dispatching. By optimizing the transmission-distribution network connection topology, the operation economy has improved while ensuring system reliability. Case studies on a realistic power system show that the mathematical model is advantageous to the optimization of the whole power grid operation.
