Problems solved by technology

[0003] The traditional microgrid economic analysis method has a very single action object, which only deals with single user types
Moreover, the configuration of hardware equipment in the park is only the basic configuration, which cannot fully supply the multi-energy complementary park with diversified hardware facilities.
However, after the site selection of the park, the relevant cost information needs to be entered manually, which is very cumbersome
[0004] At the same time, the traditional microgrid economic analysis method only considers the location of the park and the hardware facilities related to the location of the park. The data available for economic analysis is very one-sided, resulting in single output results with low accuracy and low reference value.

Embodiment Construction

[0094] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail, convenient to understand the present invention clearly, but they are not construed as limiting the present invention.

[0095] like figure 1 As shown, the processing flow of the method for the energy configuration analysis of the multi-energy complementary park in the present invention is as follows:

[0096] Step 1: Build a database of economic fundamental parameters.

[0097] The information stored in the economic basic parameter database includes: the construction period of the project is 1 year, the operation period is 25 years, the depreciation period is 25 years, the benchmark rate of return is 8%, the loan interest rate is 4%, and the proportion of loans to the total investment 80%, the loan period is 10 years, the residual value rate of the project is 5%, the sales cost ratio is 5%, the value-added tax rate is 16%, the income tax rate, th...

Abstract

The invention relates to the technical field of energy configuration analysis, in particular to a method for multi-energy complementary park energy configuration analysis. The method comprises steps of constructing an economic basic parameter database; Collecting park address data, park business scene data, park land area data and park energy condition data; Inputting hardware configuration information of the supply side, the transmission side, the demand side and the platform side, wherein the hardware configuration information comprises cost information; Calculating engineering static totalinvestment according to the cost information of the supply side, the transmission side, the demand side and the platform side; Calculating the heat supply quantity, the cold supply quantity and the annual electricity sale quantity of the park according to the park land area data and the park energy condition data; And according to the park address data, the park business scene data, the park landarea data and the park energy condition data, and in combination with data information of an economic basic parameter database, calculating an investment recovery period and an internal recovery rate.The method can be applied to various parks, has a more comprehensive economic analysis function, and is more accurate in output data and high in reference value.

Description

technical field [0001] The invention relates to the technical field of energy allocation analysis, in particular to an analysis method for energy allocation in multi-energy complementary parks. Background technique [0002] In order to facilitate the construction of the park, it is necessary to benefit the energy system of the park. The traditional economic analysis method for the power grid determines the local wind, light and other natural resource conditions through satellite positioning of the project location, and selects user types (residential, community, commercial and industrial), whether to connect to the grid, hardware facilities (photovoltaic, wind turbines), etc. , diesel engine, etc.), set the sensitivity conditions and simulate, calculate the relevant economic indicators of the park, and provide reference for the park construction. [0003] The traditional microgrid economic analysis method has a very single action object, which only deals with single user ...
