Embodiment Construction

[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0039] like figure 1 As shown, an energy interconnection planning method based on the access of the park energy station to the distribution network of the present invention includes the following steps:

[0040] Step 1: Obtain the forecast demand for cooling, heating and electricity loads of the energy station in the park;

[0041] 1. The planned electric load of the energy station in the park is calculated by the load density method. The calculation formula is as follows:

[0042] Predicted load = load density (kW / hm 2 )*Site area (hm 2 );

[0043] In the formula, the load density can be calculated using the load density data table shown in the following table. ...

Abstract

The invention discloses an energy interconnection planning method for accessing to a power distribution network based on a park energy station. The method comprises steps of firstly acquiring prediction requirements of cold, hot and electric load of a park energy station; then, according to the load type of the park energy station and the accessed transformer station, classifying energy stations,and selecting power supply modes and capacitance of the energy stations; according to the geographical position of the park and the weather, determining a distributed photovoltaic construction scheme;analyzing proportion occupied by the cold, hot and electric load of users near the energy stations, and designing triple generation capacitance; and finally, calculating the investment cost of the construction of the energy stations. According to the invention, by analyzing the power supply conditions and the load conditions of the park energy stations, a complete planning process is proposed forthe power distribution network adopting the energy interconnection; and a feasible planning path is provided for the power distribution network of a large number of new energy access electric power systems in the future.

Description

technical field [0001] The invention relates to the field of power system planning, in particular to an energy interconnection planning method based on a park energy station being connected to a distribution network. Background technique [0002] Domestic comprehensive energy utilization planning is a new field under the development of low-carbon economy. It mainly promotes a new independent energy supply model in a special area of ​​the city (from a large development zone, park or a building) to improve the cleanliness of energy utilization. and utilization efficiency. The planning and preliminary research of such projects require comprehensive load forecasting methods as the basis and basis for energy allocation. [0003] The frequent occurrence of environmental problems leads to the need to improve the energy structure. After adding new energy to the distribution network, the traditional distribution network planning method will need to be adjusted. And due to the short...
