Embodiment 1

[0087] Embodiment 1: see attached figure 1 , a planning analysis method for distributed and centralized development of clean energy, which includes the following steps:

[0088] A. Determine the planning level year.

[0089] B. Assess the potential of clean energy resources in the country to be developed.

[0090] According to the distribution of resources in the country / region to be developed, calculate the upper limit of the clean energy theoretically developable amount, technically developable amount and economic development potential of the area, and plan the area in combination with the development goals and resource potential of the country / region to be developed The total amount of clean energy that can be developed in a horizontal year is used as a constraint.

[0091] C. Calculate the cost of power generation under the centralized and distributed development methods of clean energy in the countries / regions to be developed.

[0092] Determine the financial parameter...

Embodiment 2

[0164] Example 2: On the basis of Example 1, a case study is carried out on the planning of clean energy development in North Africa and South Africa, and the selection of transmission channels and transmission capacity for non-European grid transmission methods.

[0165] A. Determine the planning level year.

[0166] B. Assess the potential of clean energy resources in North Africa and South Africa.

[0167] The analysis of the economics of wind power and photovoltaic power generation in Africa mainly considers basic influencing factors such as initial investment costs and financial parameters, and is divided into three analysis scenarios: high utilization hours, medium utilization hours, and low utilization hours. Collect the specific boundary condition parameters for the cost calculation of wind power and photovoltaic power generation in Africa, as shown in the table below:

Abstract

The invention relates to the technical field of power system analysis and provides a planning analysis method of a distributed and centralized development mode of clean energy, comprising the following steps: A. determining a planning level year; B. Assessment of the clean energy resource potential of the country/region to be developed; C. estimating the generation cost under the centralized and distributed development modes of clean energy; D. determine that constraint conditions of the plan analysis model of the centralized and distributed development mode of the clean energy; E. constructing a planning and analysis model of centralized and distribute development mode; F, selecting and calculating that cross-continental outward channel of the rich resources; G. outputting optimal transmission channel plan. The present invention provides quantitative measurement results for accurately estimating the centralized and distributed development scale, layout, development economy and outgoing channel selection of clean energy in a country or region in the future level years, and provides planning basis for future development mode of clean energy in a region rich in global resources.

Description

technical field [0001] The invention relates to the technical field of power system analysis, in particular to a planning analysis method of a clean energy development mode. Background technique [0002] On a global scale, the strategic vision of building a global energy internet has been increasingly widely recognized. At present, the transcontinental transmission of clean energy is still in its infancy, and the discussion of the corresponding centralized and distributed development methods of clean energy is becoming more and more intense, but it is limited to qualitative analysis, and there is no quantitative planning and analysis of distributed and centralized development methods. The calculation method of the scale, layout, economy, etc. in the selected area. [0003] Clean energy development can generally be divided into two development methods: centralized development and distributed development. "Distributed" is a relative concept, relative to "centralized". Regar...
