[Abstract]:At present, the high voltage problem of urban cable distribution network affects the safe operation and high quality power supply of power grid, and the rigid grid connection of clean energy further aggravates this phenomenon. Flexible grid connection is an important feature of active distribution network, which can be adjusted and optimized from two aspects of active and reactive power. In this paper, the method of photovoltaic and energy storage optical storage system participating in the optimal operation of active distribution network is put forward, the topological structure of optical storage system is given, and the flexible grid-connected model of optical storage system is established; the optimal operation model of active distribution network with the goal of minimizing the loss of "source-network" is constructed, and the multi-dimensional dynamic programming algorithm is used to solve the problem of time series continuity of energy storage and active power / reactive power decision in the model. The simulation results show that the flexible optical storage system has strong power flow regulation ability, and the optimization method realizes the goals of clean energy full absorption, distribution network economic operation and voltage overrun control.
