The randomness, volatility and un-dispatch ability of large-scale new energy connected to the grid have caused a series of problems with the stable operation of the grid and great difficulties with power dispatch. The configuration of the energy storage power station and substation is studied through the metering and reliable capacity planning method of energy storage power station and substation capacity planning. This will improve the level of utilization of grid assets and promote the coordinated development of new energy, energy storage and the grid.

“…The reasons for all above problems are weakly controlled and high singularity characteristics of clean energy. And these problems are manifested in the lack of urban generation capacity and the lack of resilient power resources in urban grids with large loads [1,2] .…”

Under the carbon neutrality vision, the proportion of clean energy in urban power grids is inevitably increasing, which poses many problems for the dispatching mode of distribution grids. In this paper, based on the analysis of the coupling relationship between carbon emission intensity index and intermittent power, a new dispatching model for energy systems in a smart city environment is proposed. Firstly, a distribution grid dispatching model considering carbon emission index is put forward. Next, the distribution network optimal dispatching model is established and solved by the Mixed Integer Second-Order Cone Programming (MISOCP) algorithm. Finally, the effectiveness of the proposed method is verified on a modified IEEE 33 nodes system.

“…e impact of multi-microgrid high-permeability grid connection on distribution managers not only stays at the physical level such as the traditional trend direction, size changes, and node voltage changes, and the network reconstruction and reactive power optimization caused by it [1][2][3][4]. e solution is not only the optimization goal of the distribution network when multiple grids are connected to the grid and an optimal scheduling algorithm that seeks a global optimal solution [5][6][7].…”

This paper investigates the network coordination, self-regulation mode, and autonomous control spatial planning of microgrid. To do this, the cooperative self-discipline model of multi-microgrid intelligent distribution network is constructed. Based on combing the power control of multi-microgrid with high penetration situation, the concept and characteristics of distribution network and self-regulation mode are defined according to the new requirements, and the basic framework and decision-making process of self-regulation mode are put forward. Further, the formulation method of autonomous spatial planning for multi-micronetworks is described. By constructing cooperative self-discipline space scheme and its reward and punishment mechanism, the network operation behavior is restrained and guided, and the control dimension of the distribution network is reduced. Finally, a typical case is given to illustrate the effectiveness of cooperative self-discipline supervision mode in reducing the space-time dimension of distribution network supervision.
