Description

Technical Field

[0001] This utility model relates to the field of combined energy supply, and in particular to a combined wind, solar and energy storage system for substations. Background Technology

[0002] Against the backdrop of today's energy transition, the emergence of substation wind-solar-storage combined energy supply systems is of great significance. On the one hand, reducing the use of traditional fossil fuels and developing renewable energy has become an inevitable trend; on the other hand, the requirements for the stability and reliability of power systems are increasing.

[0003] In existing technologies, wind-solar combined energy storage systems can provide substations with a stable and reliable power supply, improve energy self-sufficiency, utilize local wind and solar energy resources, reduce dependence on traditional power grids, and achieve energy self-sufficiency for substations to a certain extent. However, since most solar panels are fixedly installed facing one direction, the power generation efficiency is highest only when the solar panels can maintain a perpendicular angle to the sunlight at a certain moment. Therefore, fixedly installed solar panels cannot utilize solar energy for power generation at the maximum efficiency.

[0004] Therefore, it is necessary to propose a combined wind, solar and energy storage power supply system for substations to solve the above problems. Utility Model Content

[0021] Wind energy conversion module 2 is electrically connected to power storage module 3;

[0022] See also Figure 1 When the electrical energy generated by the wind energy conversion module 2 exceeds the current demand, the excess electrical energy can be stored in the power storage module 3, which can avoid energy waste and improve the overall utilization efficiency of wind energy. Secondly, wind energy is intermittent and unstable, and its output power will fluctuate with the change of wind speed.

Whenever there is a power supply, the user's hot water needs, such as for washing, bathing, and cleaning, can be met. The thermostatic control component 15 ensures that the water temperature in the tank is always maintained within a suitable range, avoiding excessively high or low temperatures and providing a comfortable water experience.
