// The following are the common application scenarios of the PV-storage Flexible DC Integrated Machine:

1.  Distributed Energy Connection

Driven by the "dual carbon" goals, distributed energy has been developing rapidly. However, traditional connection methods often lead to problems such as voltage fluctuations and harmonic interference. Through flexible DC transmission technology, the PV-storage Flexible DC Integrated Machine can efficiently connect distributed photovoltaic power generation and energy storage systems to the power grid, ensuring stable energy transmission. For example, after a certain industrial park installed a photovoltaic power generation system on the rooftops, with the help of the PV-storage Flexible DC Integrated Machine, it not only achieved on-site consumption of the photovoltaic power generation but also increased the efficiency of feeding surplus electricity into the grid by 15%, effectively solving the power quality problems in the connection of distributed energy.

2.  Microgrids

The construction of microgrids in remote areas faces challenges such as unstable energy supply and difficulties in interconnection with the main power grid. The PV-storage Flexible DC Integrated Machine can serve as the core equipment of a microgrid, precisely coordinating the energy flow among power sources, energy storage, and loads. Taking an island microgrid as an example, the PV-storage Flexible DC Integrated Machine makes full use of the abundant solar energy on the island. Combined with the energy storage system, it provides stable power for the island residents and industries. Even when the microgrid is separated from the main power grid, it can still maintain independent and stable operation for more than 72 hours, significantly reducing the dependence on traditional energy sources such as diesel power generation.

3.  Energy Storage Power Stations

Energy storage power stations have extremely high requirements for the precision of charge and discharge control and energy management. Relying on advanced control algorithms and flexible DC transmission technology, the PV-storage Flexible DC Integrated Machine greatly improves the response speed and regulation ability of energy storage power stations. In a certain large-scale energy storage power station project, the PV-storage Flexible DC Integrated Machine helps the power station achieve a millisecond-level response to changes in the power grid load, efficiently perform peak shaving and valley filling operations during peak and off-peak periods, increasing the operation efficiency of the power grid by about 20%. At the same time, in case of a power grid failure, it can provide up to 4 hours of emergency power support for important surrounding users.

4.  Smart Grids

In the construction of smart grids, the PV-storage Flexible DC Integrated Machine is a key node for realizing two-way interaction between the power grid and users. Through in-depth integration with devices such as smart meters and smart homes, it can accurately sense users' electricity consumption demands and the operation status of the power grid. When the power grid is under peak load, the PV-storage Flexible DC Integrated Machine can automatically guide users to reduce unnecessary electricity consumption; during off-peak load periods, it can encourage users to increase electricity consumption, achieving the optimal allocation of power resources. After a certain pilot community applied this device, the power grid load rate increased by 18%, and the average electricity consumption cost for users decreased by 12%.

5.  Electric Vehicle Charging

With the rapid increase in the number of electric vehicles in use, the pressure exerted by traditional charging piles on the power grid has become increasingly prominent. The PV-storage Flexible DC Integrated Machine provides DC fast charging services for electric vehicles and combines with photovoltaic power generation and energy storage to create a green and intelligent charging mode. At the charging stations in expressway service areas, the PV-storage Flexible DC Integrated Machine uses photovoltaic power generation to charge electric vehicles, and the energy storage system supplements electricity when the photovoltaic power is insufficient. This not only reduces the impact of the charging stations on the power grid but also increases the charging efficiency of a single pile by 30%, effectively alleviating the problem of queuing for charging during holidays.

6.  Power Supply in Remote Areas

In areas such as mountainous regions and grasslands far from the main power grid, the extension of conventional power grids is costly and difficult. The PV-storage Flexible DC Integrated Machine can utilize the abundant local solar energy resources and, through flexible DC transmission technology, transmit electricity tens of kilometers away. After the PV-storage Flexible DC Integrated Machine project was completed in a certain border village, it ended the long history of no electricity supply in the area, provided 24-hour stable power for the villagers, and also supported the development of small-scale processing industries, contributing to rural economic revitalization.
