Abstract

The invention relates to an active power distribution network multi-target layered planning method considering demand side management and energy storage; the method comprises the following steps: building a dual-layer model; the upper planning model integrally considers various economic costs of a power distribution company in a planning process and the reliability and stability of the power distribution network as the upper layer goals, considers the demand side management and energy storage equipment investment and economic benefits, and determines a target function and constraint conditions; the lower planning model takes the minimum distribution power resection volume in the planning process as the target function, considers the maximum effective utilization of the distributed power supply, reduces the distributed power supply output via wind and light curtailment measures, and adjusts transformer tap joint and reactive compensation equipment to carry out active control. The methodcan improve the power supply reliability and distribution network operation stability, and can delay power grid upgrades.

Description

technical field [0001] The invention relates to a multi-objective hierarchical planning method for an active distribution network considering demand-side management and energy storage. Background technique [0002] As the proportion of multi-type distributed generation (DG) connected to the distribution network continues to increase, and the application of controllable equipment such as flexible loads continues to increase, the traditional distribution network planning cannot meet the needs of high penetration rates under the background of a low-carbon economy. Requirements for efficient utilization of DG. Therefore, it is urgent to carry out research on active distribution network planning that takes into account demand-side management and energy storage, realize active consumption and multi-level coordinated utilization of various renewable energy sources, reasonably control uncertain factors such as flexible loads, and change network topology. To improve system reliabili...
