A New Energy Consumption Method Based on Power Generation Frequency Limit Adjustment

Abstract

The invention discloses a new energy accommodation method based on the power generation frequency limit value adjustment, and the method gives consideration to the improvement of the operation frequency limit value of a power grid in a reasonable range when a system is in normal operation and in a time period of low load, stabilizes the characteristics of randomness, fluctuation and reverse peak regulation of new energy power generation, and improves the accommodation capacity of the system for new energy power generation. The method comprises the steps: constructing a new energy accommodation model inference model based on the power generation frequency limit value adjustment, wherein the system can accommodate more new energy output through primary frequency modulation during normal operation; accommodating the new energy in a low load time period through reducing the technical output of the conventional energy resource, wherein the new energy, which is not completely accommodated, can be used for solving the change transient process of the frequency and a new steady-state value of the system after new energy grid connection through an inference formula after the conventional energy resource has already reached the minimum technical output. According to the embodiment of the invention, the method improves the new energy accommodation capacity of the power grid during normal operation and the low-load time period through the real-time dynamic adjustment of the frequency of the power grid.

Description

technical field

[0001] The invention relates to the fields of power system operation control and new energy consumption, in particular to a new energy consumption method based on power generation frequency limit adjustment. In order to improve the new energy consumption capacity of the power grid during low load periods. Background technique

[0002] Electricity is an important economic lifeline of the country, and the current world energy crisis and environmental problems are becoming increasingly prominent. With the continuous development and maturity of new energy power generation technology, it is an inevitable trend for the future power grid structure to have a high proportion of new energy. Improving the system's ability to absorb new energy is an effective measure for the sustainable and green development of the power grid.

[0003] However, as primary energy sources, wind energy and solar energy cannot be stored, and the electric energy generated by them has the cha...
