Calculation and evaluation of grid electricity price for wind farms
Zheng Xiujun
Summary: The Electricity price is a constraint on the development of wind power generation. The most critical factor is to encourage the development of wind power generation and ensure reasonable profits on investment in wind power projects. . The electricity price model for wind power generation is mainly established by calculating the internal rate of return. (IRR). Based on the analysis of the mathematical model, specific research was carried out. The impact of various factors on electricity prices was carried out, and confirmed research was carried out to establish an index system for wind grid electricity calculation and evaluation. price. Combine research work with the specific realities of wind companies, focusingon solving the problem of calculating wind network electricity prices, locating wind turbine equipment, reducing equipment prices and after-sales services, reducing park operating costs wind farms, doing a good job in the preliminary work of wind farms and the precise understanding of wind energy resources to create a reliable basis for accurate calculation of electricity prices on the grid. It is recommended that the on-grid wind power pricing policy be determined as a conditional fixed on-grid pricing policy and ensure the integrity and continuity of the policy.

< /p>The amount of the investmentInstallation, power generation and economic benefits of offshore wind power projects will be affected by many factors, such as the water depth of the location, wind speed, equipment selection, construction period, political subsidies, etc. Therefore, it is impossible to give a precise answer. The following provides only an approximate reference:
1. Investment amount: The investment amount for 1 GW of offshore wind power typically exceeds billions of dollars. The specific investment amount depends on the project location, equipment selection, construction period and other factors.
2. Energy production: Offshore wind energy production is related to water depth, wind speed, wind energy density and other location factors. Typically, a 1 MW offshore wind turbine can generate approximately25 energy. -35 million kilowatt hours per year. Therefore, a 1 GW offshore wind power project can generate on average around 25 to 35 billion kilowatt hours per year.
3. Economic Benefits: The economic benefits of offshore wind power include energy revenues, policy subsidies, reduced carbon emissions and other factors. Generally speaking, the investment return cycle takes several years to more than ten years, depending on factors such as the project investment amount, policy support and electricity market prices.
It should be noted that the above data is for reference only, and the specific data should be evaluated according to actual project conditions.
