摘要：
The pursuit of "double carbon" goals has made it imperative to integrate new sources of energy into distribution networks. In this context, the grid-connected configuration of optical storage is emerging as a crucial factor that affects the power quality of such networks.This paper establishes a double-layer optimal allocation model of photovoltaic and energy storage systems in the active distribution network considering the influence of power quality. The lower-level dispatching model adopts the optimal tidal model based on the second-order cone planning to dispatch each active management measure and distributed power output with the lowest system network loss as the target. The optimization of the upper-level configuration model is based on several targets, including the annual investment and operation cost of the power generation system, the power quality assessment value of each photovoltaic grid connection point, the total system abandonment rate, and the energy storage revenue. To ensure rapid and accurate calculation results, the optimization is conducted using the vector sequence optimization theory as the guiding principle. This study utilizes the IEEE-33 node system to conduct the analysis, and the results show that the optimization of the optical storage capacity of the active distribution networks considering the influence of power quality is able to ensure the economical operation of the grid while improving the power quality, which will provide a valuable theoretical support for the development and implementation of the new active distribution grids in the future. © 2024 Power System Technology Press.
