Technical Field

The present invention relates to the field of power systems, and in particular, to a power supply system configuration method, apparatus, computer device, storage medium, and computer program product.

Background

Aiming at special areas such as remote areas, plateau areas, far-shore islands and the like, the power supply circuit can not completely cover or hardly cover the areas. And the dependence of the long-distance power supply mode on the power supply line is higher, and the dependence of the micro-grid power supply mode is lower. Therefore, when power is supplied to the above-mentioned areas, the micro-grid power supply mode is often more economical than the long-distance power supply mode, and can provide better power supply quality.

For example, the micro-grid power supply mode is a power supply mode that combines multiple power generation modes such as photovoltaic power, energy storage, thermal power (power generation by using resources such as diesel, coal and the like) to form a micro-grid system, and can also be called as a light-storage-diesel combined power generation mode.

When the light firewood storage combined power generation mode is adopted for power supply, the coordination configuration of the generated energy of different power generation modes in the light firewood storage combined power generation system is needed. However, in the conventional method, when the power generation capacity of each different power generation mode in the light firewood storage combined power generation system is coordinated and configured, the phenomenon of capacity waste often occurs, so that the resource utilization rate of the light firewood storage combined power generation system is reduced.
