Problems solved by technology

[0005] This strategy only considers the revenue of distributed power generation and energy storage stations selling electricity to the grid, and energy storage can only recover costs when the operators of energy storage stations and distributed power generation are the same company. For energy storage stations, Its profit is limited, and its practical application is of little significance

Embodiment 1

[0121] see figure 1 , a distribution network planning method adapted to the development of distributed generation and energy storage stations, the following steps are adopted in sequence:

[0122] Step 1. Carry out spatial load forecasting for the distribution network area to be planned in the known planning year, and obtain the future load node distribution of the distribution network area to be planned, specifically:

[0123] Step 1.1, use the geographic information system GIS to process the space of the distribution network area to be planned, and collect land information on transportation, community, municipal administration, and commerce;

[0124] Step 1.2. Evaluate the open space to be developed in the area of ​​the planned distribution network according to the requirements of different load categories for the use conditions of the area, and divide the newly added land use types;

[0125] Step 1.3. Predict the load situation of the new land use according to the existing...

Abstract

A distribution network planning method adapted to the development of distributed power generation and energy storage stations. This method first performs spatial load prediction on the distribution network area to be planned within the planning year, and obtains the future load node distribution of the distribution network area to be planned. Then, according to the distribution of load nodes, an upper-level optimization model is established, and the model is used to obtain the optimal distribution network grid structure in the distribution network area to be planned, and then the distribution network to be planned is predicted according to the optimal distribution network grid structure The load characteristics of all load nodes in the region and the output characteristics of distributed power generation. Finally, a lower-level optimization model is established for the location, capacity and profit model of the energy storage station, and the energy storage with the best interest for the investor of the energy storage station is calculated by using this model. Station siting capacity and construction site. This design not only solves the problems of line planning and energy storage station site selection and capacity determination in power grid planning, but also maximizes the profit of energy storage stations.

Description

technical field [0001] The invention belongs to the technical field of intelligent distribution network planning, and in particular relates to a distribution network planning method adapted to the development of distributed power generation and energy storage stations. Background technique [0002] Distributed power generation technologies mainly include: wind power generation, photovoltaic power generation, tidal power generation, biomass power generation, etc. Compared with traditional power generation methods, distributed power generation has the advantages of high energy utilization rate and low environmental pollution. At present, domestic distributed power generation research results are concentrated on wind power generation and photovoltaic power generation. However, natural resources such as wind energy and solar energy are easily affected by the environment and climate. This makes wind power and photovoltaic power generation intermittent and volatile, seriously af...
