Abstract

The invention provides a new energy station energy storage capacity configuration method and device, equipment and a storage medium, and belongs to the technical field of power systems. The method comprises the following steps: respectively obtaining a first frequency parameter of a first system and a second frequency parameter of a second system after a preset fault occurs at a preset moment; under the condition that the first frequency parameter and the second frequency parameter do not meet the preset frequency condition, adjusting the energy storage capacity of energy storage equipment, and oobtaining the second frequency parameter of the second system after the preset fault occurs again until the first frequency parameter and the second frequency parameter meet the preset frequency condition; and calculating the total energy storage capacity of a target power system according to the adjusted final energy storage capacity of the energy storage equipment, and configuring the energystorage capacity of the new energy station according to the total energy storage capacity. According to the invention, the frequency regulation capability of the power system can be improved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a configuration method, device, equipment and storage medium for energy storage capacity of new energy stations. Background technique [0002] The existing power system has the following characteristics: the growth rate of thermal power, hydropower and nuclear power installed capacity is slowing down, while the growth rate of wind power, photovoltaic and other new energy units is rapid. At the same time, a large number of new energy stations have also appeared, making the proportion of installed capacity of new energy units continue to increase. [0003] However, with the continuous increase in the proportion of wind power, photovoltaic and other new energy units installed, the frequency regulation capability of the power system is reduced, resulting in the deterioration of the frequency stability of the power system. Contents of the invention [0004] In vie...
