Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] The method of the invention is proposed under the background that the demand side response participates in the peak shaving and valley filling of the active distribution network, and in the process, the reduction amount of the demand side response changes with the change of the compensation value.

[0028] A two-tier planning method for active distribution networks that takes into account the uncertainty of demand-side response in the present invention, its overall flow chart is as follows Figure 5 As shown, the method includes the following steps:

[0029] (1) Considering the uncertainty of wind power generation and photovoltaic power generation, establish a time series model of wind turbines and photovoltaic cells;

[0030] In step (1), the time series model of the wind turbine and photovoltaic cell is set up, and its specific process is as follows:

Abstract

The invention discloses an active power distribution network double-layer planning method considering demand side response uncertainty. The content includes building a time sequence model of a wind turbine generator and a photovoltaic cell with consideration given to uncertainty of a wind power generation and photovoltaic power generation; building a time sequence model of a load with consideration given to randomness of power utilization of the load; making an analysis of demand side response uncertainty of a direct load control type, and building a cost function; building an upper layer planning model of active power distribution network double-layer planning considering the demand side response uncertainty, and adopting a differential evolution algorithm to solve the upper layer planning model; and building a lower layer planning model of the active power distribution network double-layer planning considering the demand side response uncertainty and adopting a non-dominated sorting genetic algorithm to solve the lower layer planning model. The active power distribution network double-layer planning method performs planning of an active power distribution network, can effectively reduce the comprehensive cost of the power distribution network, better meets the running characteristic of the active power distribution network, and is high in practicability.

Description

technical field [0001] The invention relates to the field of distribution network planning, in particular to a two-layer planning method for an active distribution network considering the uncertainty of demand-side response. Background technique [0002] In recent years, with the increasing penetration of distributed energy resources (DER), such as distributed power generation, energy storage systems, and controllable loads, traditional distribution networks are facing challenges in terms of operational flexibility, safety, and economy. This is a big challenge, so Active Distribution Networks (ADN) came into being. The active distribution network, as a more flexible network, puts more emphasis on active planning. In the planning stage, the integrity of planning, construction and operation should be considered, and the "garbage power" of distributed power should be absorbed to the greatest extent, so as to achieve low-carbon power generation. Therefore, it has important the...
