Embodiment Construction

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0053] Since the installed capacity of new energy in the power system has shown a proportional explosive growth, how to reasonably consume new energy based on the existing resources, configuration and control methods of the power grid has important practical significance. However, to study the problem of new energy consumption, it is necessary to comprehensively consider various factors. The technical solution provided by the embodiment of the present inve...

Abstract

The invention discloses a method for determining the proportion of new energy in a power system, including: establishing a comprehensive system frequency response model, and determining the maximum proportion of new energy that meets frequency stability requirements based on the system frequency response comprehensive model; according to the The maximum proportion of new energy, detecting the voltage stability in the power system, if the voltage stability does not meet the predetermined requirements, adjusting the maximum proportion of new energy in the power system until the voltage stability meets the predetermined requirements, And the maximum proportion of new energy in the power system that meets the predetermined requirements is taken as the proportion of new energy allowed in the power system. The present invention focuses on the two aspects of frequency stability and voltage stability of the power system, and studies the evaluation method of the proportion of new energy allowed in the power system, so as to realize the maximum consumption of new energy, thereby efficiently solving problems caused by system stability. The waste of new energy consumption capacity.

Description

technical field [0001] The invention relates to the field of electric power technology, and in particular, to a method for determining the proportion of new energy in an electric power system. Background technique [0002] Under the background of vigorous development of new energy power generation, the uncertainty and randomness of new energy output power have a profound impact on the operation and control of power grids. On the one hand, this uncertainty of new energy requires the power grid to provide sufficient reserve capacity, if the uncertainty of the output power of new energy is excessively considered, it will cause a serious waste of resources. On the other hand, the randomness of new energy requires a high degree of flexibility in the control capability of the power grid. At present, the main unit type in the power grid is thermal power with a relatively slow regulation rate. Even if the unit is transformed based on certain technical means, it is still far from bei...
