The invention discloses a power supply method and system for a new energy power generation hybrid scene. The power supply method for the new energy power generation hybrid scene comprises the following steps of: acquiring an expected power supply demand of a pre-estimated target load; estimating electric energy which can be output by the current new energy; judging whether other electric energy is needed or not according to a result of comparison between the expected power supply demand and the estimated electric energy; under the condition that the judgment result shows that other electric energy is needed, determining demand values corresponding to the other electric energy based on the difference value between the expected power supply demand and the estimated electric energy; and supplying power to the target load based on the estimated electric energy capable of being output by the current new energy and demand values corresponding to other electric energy. According to the power supply method and system for the new energy power generation hybrid scene, energy waste can be avoided, and lack of energy supply can also be avoided.
Description
technical field [0001] The present invention relates to the technical field of new energy control, in particular to a power supply method and system for a mixed scene of new energy power generation. Background technique [0002] The hybrid energy system is an energy system based on the integration of solar energy, wind energy, diesel power generation, mains power, and energy storage batteries. It can reduce the overall cost of the system, save fuel, reduce pollution, and improve the power supply guarantee rate of the system. Available For the full-load power demand of islands, base stations, etc. New energy sources include solar energy, wind energy, energy storage batteries and other energy sources. In the existing technology, the power supply does not distinguish between new energy sources and ordinary energy sources. The existing power supply methods are likely to cause energy waste or insufficient energy supply. Contents of the invention [0003] The purpose of the pre...
