Abstract

The invention is suitable for the technical field of urban network planning, and provides an extension planning method and device for an active power distribution system, and terminal equipment, the method comprises the steps: building a power distribution network double-layer optimization model and an interruptible load response model of a user side, wherein the power distribution network double-layer optimization model comprises a network frame planning layer model and an operation scheduling layer model; randomly encoding the to-be-extended route in the target planning area according to theconstruction state to generate a first population; performing random coding on the basis of the first population according to a target interrupt load proportion to generate a second population; and solving the optimal particles in the first population and the second population in combination with an interruptible load response model, and determining an optimal grid planning scheme and a corresponding optimal operation scheduling scheme. Through the active power distribution system extension planning method provided by the invention, the solution of the optimal extension planning scheme of theactive power distribution system considering the load demand response capability of the user side in a scene with intermittent new energy access can be realized.

Description

technical field [0001] The invention belongs to the technical field of urban network planning, and in particular relates to an expansion planning method, device and terminal equipment of an active power distribution system. Background technique [0002] With the development of new energy, there are more and more scenarios where large-scale intermittent new energy is connected to the grid. Due to the intermittent characteristics of wind energy, solar energy and other new energy sources, the supply of such distribution networks has certain uncertainties. In order to adapt to such uncertainties, it is necessary to adjust the load on the user side and introduce a demand response mechanism, and adjust the load on the user side so that there is interaction between the user and the distribution network. A reasonable demand response mechanism can guide the user's electricity consumption behavior, promote the consumption of distributed power output, and then reduce the construction ...
