Abstract

The invention discloses an active power distribution network planning and operation combined optimization method comprising the following steps: listing decision variables according to an alternative planning scheme; listing object functions according to a planning object, wherein the functions comprise planning period investment construction cost, operation maintenance cost, power transaction cost and power supply reliability indexes; listing planning constrain items; listing operation constrain items; generating an active power distribution network planning and operation combined optimization model according to the object functions and constrained conditions; calculating the optimization model so as to obtain an optimized decision. The method optimizes decision variables through the active power distribution network planning and operation combined optimization model, thus determining a best construction scheme of the power distribution network with energy storage, and improving power grid energy storage system and line asset utilization rate.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an active distribution network planning and operation joint optimization method. Background technique [0002] Distribution network expansion planning is an important research field in power system planning. In recent years, the ADN (Active Distribution Network) concept proposed by CIGRE in 2006 has become the focus of many scholars in the field of power planning. An important feature of ADN is that the integrated control system controls various forms of DER (Distributed Energy Resources, distributed energy), such as DG (Distributed Generation, distributed generation), CL (Controllable Load, controllable load) and ESS ( Energy Storage System, energy storage system). Obviously, the integration of DER will have a great impact on the expansion planning of traditional distribution network. [0003] Traditional distribution network planning can be divided into: substation plann...
