While wind and solar energy are clean and renewable energy sources, they are intermittent and unstable, meaning their power generation fluctuates with weather and time variations. To address this, energy storage technology is introduced into the system to store excess energy and release it when needed, thus balancing supply and demand. In practical applications, wind, solar, and energy storage equipment can improve the utilization rate and reliability of intermittent power sources, achieving uninterrupted and stable power supply. Furthermore, to achieve deep integration of wind, solar, and energy storage, multiple aspects need to be considered, including grid connection stability, power generation costs, energy storage utilization rate, and technological maturity. Energy storage technology is crucial for new energy systems, improving the utilization rate and absorption capacity of wind and solar power generation, forming a stable system to address future energy security issues.

[0028] This invention proposes a wind-solar-storage equipment 100.

[0029] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the wind-solar-storage equipment 100 includes a housing 1, a power supply device 2, a converter 3, an inverter 4, and an energy storage system 5. The housing 1 is provided with an installation slot 1a and also includes two partitions 11, both of which are connected to the housing 1 and are located within the installation slot 1a. Both partitions 11 extend along the bottom to the opening of the installation slot 1a, dividing the installation slot 1a into three compartments 11a. The power supply device 2 is used to provide electrical energy to the wind-solar-storage equipment 100 and is located outside the housing 1. The converter 3 and the power supply device 4 are connected to the installation slot 1a. The power supply unit 2 is electrically connected to the converter 3, which is capable of converting and distributing the electrical energy provided by the power supply unit 2. The converter 3 is movably connected to the enclosure 1. The inverter 4 is electrically connected to the converter 3 and is used to convert the electrical energy converted by the converter 3 into AC power. The inverter 4 is movably connected to the enclosure 1. The energy storage system 5 is electrically connected to the converter 3 and is used to store the electrical energy converted by the converter 3. The energy storage system 5 is movably connected to the enclosure 1. The converter 3, inverter 4, and energy storage system 5 are arranged at intervals, and the converter 3, inverter 4, and energy storage system 5 are each located in a compartment 11a.

[0030] In this embodiment, the interior of the enclosure 1 is divided into three compartments 11a by partitions 11. These three compartments 11a are used to house the converter 3, inverter 4, and energy storage system 5, respectively, thereby optimizing space utilization and improving the stability of equipment operation. Specifically, the interior of the enclosure 1 is divided into three compartments 11a by two partitions 11, with each compartment 11a independently housing the converter 3, inverter 4, and energy storage system 5. This modular design facilitates the transportation, installation, and maintenance of the equipment, while also improving its neatness and aesthetics. The design of the compartments 11a also helps to isolate heat and electromagnetic interference generated by different components, thereby improving the stability and lifespan of the system. The power supply unit 2, located outside the enclosure 1, provides electrical energy to the wind-solar-storage equipment 100. This design makes it easy for the power supply unit 2 to be connected to independent wind and solar power generation systems, and also facilitates the maintenance and upgrading of the power supply unit 2. The converter 3 is electrically connected to the power supply unit 2 and is responsible for converting and distributing the electrical energy provided by the power supply unit 2. The converter 3 is movably connected to the enclosure 1, facilitating replacement or maintenance when needed. Inverter 4 is electrically connected to converter 3, converting the DC power generated by converter 3 into AC power for equipment use or grid connection. Inverter 4 also employs a movable connection to improve maintenance convenience. Energy storage system 5 is electrically connected to converter 3 to store excess energy and release it when needed. The movable connection design of energy storage system 5 also considers ease of maintenance and upgrades. The enclosure 1 and partition 11 are typically made of durable, environmentally resistant materials such as aluminum alloy, stainless steel, or high-strength plastics to ensure their strength and durability, while also considering corrosion resistance and insulation to protect internal components and ensure safe operation.

[0031] In one embodiment, the power supply unit 2 refers to an integrated system of wind power generation and solar power generation, which together provide electrical energy to the wind-solar-storage device 100. The wind turbine captures wind energy and converts it into mechanical energy, which is then converted into electrical energy by a generator. The selection principle for the rated power and rated wind speed of the wind turbine is that although wind energy itself does not incur usage costs, the power generation equipment used to realize the energy conversion process does. Therefore, the efficiency of the wind turbine directly affects the emission reduction effect and the return on investment. When selecting a wind turbine, its performance under low wind speed conditions should be considered, as low-wind-speed models typically generate more electrical energy at the same rated power. The solar photovoltaic cell array directly converts sunlight into electrical energy through solar cells. The configuration of the solar photovoltaic cell array should be designed according to the local sunshine hours and solar radiation intensity to ensure that the system can maximize the utilization of solar energy resources.

[0032] It should be noted that converter 3 is generally a DC converter 3 or an AC converter 3. In this wind-solar-storage equipment 100, a DC multi-port converter 313 is commonly used. Specifically, the DC multi-port converter 313 can achieve efficient power conversion between multiple DC ports. The DC multi-port converter 313 adopts a design using a shared switching transistor or a shared magnetic core. Through inductor current multiplexing, power exchange between multiple ports can be achieved with only a single inductor, reducing the cost and size of converter 3. For example, the photovoltaic DC / DC converter 3, medium-voltage DC / DC converter 3, bidirectional DC / DC converter 3, and DC / AC converter 3 are all connected via a DC bus. Each converter 3 serves as one port of the multi-port DC converter 3, connecting to different power sources or loads. Each converter 3 controls its own operating state based on the DC bus voltage and the deviation between the reference bus voltage and its corresponding value, maintaining the DC bus voltage as the voltage reference value. This control method achieves autonomous switching of DC bus voltage control, ensuring stable system operation even in the event of a port failure. An inverter is a power electronic device that converts direct current (DC) to alternating current (AC) and is widely used in photovoltaic power generation, wind power generation, and electric vehicles.

[0033] The compartment 11a design optimizes the internal space layout and improves the space utilization of the equipment. Converter 3, inverter 4, and energy storage system 5 are all movably connected to enclosure 1, facilitating maintenance and upgrades. The compartment 11a design helps isolate interference between different components, improving system stability and lifespan. By rationally configuring the energy storage capacity, the complementary characteristics of wind, solar, and energy storage systems can be fully utilized, optimizing the economy of energy storage system 5 and tie-line power fluctuations. Regarding the material of enclosure 1, durable and environmentally resistant materials such as aluminum alloy, stainless steel, or high-strength plastics are typically chosen to ensure the strength and durability of enclosure 1, while also considering corrosion resistance and insulation to protect internal components and ensure safe operation.

The partitions 11 extend from the bottom to the opening of the installation slot 1a, dividing it into three compartments 11a. This achieves a compact and reasonable layout of the converter 3, inverter 4, and energy storage system 5. Specifically, by providing three compartments 11a within the housing 1, the wind-solar-storage equipment 100 isolates and houses the converter 3, inverter 4, and energy storage system 5, ensuring the independence of each component and ease of maintenance. Furthermore, the design of the partitions 11 enhances the overall stability and safety of the equipment. This layout effectively improves space utilization, reduces the complexity of internal wiring, and minimizes energy loss during transmission, thereby increasing energy conversion efficiency. Furthermore, the flexible connection design allows converter 3, inverter 4, and energy storage system 5 to be flexibly configured according to actual needs, enhancing the adaptability and scalability of the equipment.
