Problems solved by technology

How much new energy power is transmitted across provinces and regions, and the proportion of new energy power transmitted to the total power transmission is difficult to accurately calculate
[0005] Moreover, there is no real-time push mechanism and regular push mechanism for the new energy power information in the existing technology, so that the provinces and cities cannot obtain new energy power in time, and cannot formulate power consumption strategies according to actual conditions, and can not get real-time updates. In the case of new energy power, it is impossible to adjust the power plan in time, which leads to the problem of not being able to maximize the use of new energy power

[0105] The invention relates to a method for pushing information on the proportion of new energy sent by tie lines. The method is based on the real-time power generation of various power sources in the sending-end power grid, and according to the magnitude of the power at different times in the cross-province and cross-region power transmission curve, corresponds to the new energy in the sending-end power grid at that time. The proportion of energy power generation can be multiplied and accumulated to get the size of new energy electricity transmitted across provinces and regions. At the same time, the proportion of new energy electricity in all electricity transmission in this period can be obtained. Based on the proportion of new energy electricity, the new energy electricity of each province Push energy information so that provinces can adjust power consumption plans in a timely manner, save economic costs, and achieve the purpose of rational use of new energy.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of new energy management, and in particular relates to a method and system for pushing new energy ratio information sent by a contact line. [0003] 【Background technique】 [0004] As a clean new energy, wind power and solar power generation can not only alleviate the tension of electricity consumption, provide sustainable power for economic development, but also reduce the excessive dependence on traditional fossil fuels and energy saving. and environmental protection are of great significance. All countries in the world are vigorously advocating the development of new energy sources such as wind power and photovoltaic power generation. When new energy-rich areas transmit electricity to other provinces, they usually require a certain proportion of new energy electricity. However, wind power and photovoltaic power generation have the characteristics of randomness and volatility, and cannot maintain continuou...
