Island economy: can not do without reliable power support

The blue sea and soft sandy beaches are desirable. 

In recent years, the popularity of "island tour", "island + camping" and "island + brigade shooting" has continued to rise. 

According to statistics, Hainan (China's second largest island) received more than 90 million domestic and foreign tourists in 2023. 

The development of island economy needs stable electric energy guarantee. 

In recent years, relevant policies have been issued across the country to promote island microgrids, such as the "14th five-year Plan", "guidance on promoting the Construction of New Energy Microgrid demonstration projects", "notice on Printing and Printing of Guangdong Province to promote the Development of New Energy Storage Power stations", "Ten measures to support Island Revitalization issued by the Office of the people's Government of Fuding City" and so on. 

Build new power systems such as island microgrid, offshore charging network and high-energy distribution network to create a low-carbon ecological island.

                                                                                 What is the island microgrid?

The power grid is composed of distributed power generation, power load, energy storage facilities, distribution facilities, system monitoring and protection devices, etc., with complete power generation, transmission and distribution functions, including power generation, power consumption, energy storage, regulation and protection and so on. 

Island microgrid is a kind of microgrid specially used in island environment.

Microgrid can be regarded as a small power system, which supports off-grid spontaneous self-use and local consumption. It is suitable for islands, remote areas and other areas where large power grids are difficult to reach, to ensure the power supply of local areas. 

As a "potential stock" in the electric power field, the value of microgrid is that it can realize the spontaneous self-use of electric power, realize compatibility and complementarity with large power grid, and enable the power grid to absorb a large amount of renewable distributed energy and promote the efficient use of green energy. 

Microgrid can be connected to the external grid or run off the grid, which is an important part of the smart grid.

                                                         Why do island microgrids need to store energy?      

The microgrid is mainly distributed power supply, which can be adjusted by energy storage system and control device to meet the load demand. 

The addition of energy storage system can reduce the abandonment of wind and light, make the microgrid have the characteristics of a new power system, make the microgrid more flexible, stable and reliable, solve the problem of source load imbalance of new energy connected to the grid, and realize the local absorption of new energy. promote the coordinated development of "source network load", and at the same time solve the problems of "uninterrupted power" and "good use of electricity" for the islands.

In the island application scenario, the combination of microgrid and energy storage closely meets the needs of the new power system, solves the problem of mechanization and simplification of large power grid, and improves energy efficiency and power supply reliability.

                                                 Kortrong helps the Island to realize "Free use of electricity"

Kortrong energy storage, born in Zhuhai, a city of a hundred islands, gives full play to its geographical advantages, makes an in-depth analysis of the island's energy demand, and innovates the "island microgrid + energy storage solution" to support photovoltaic access and firewood access. It can build off-grid / parallel-grid island microgrid and configure self-developed energy storage system (integrated optical storage machine, integrated liquid-cooled energy storage system, etc.). 

And through the energy management system EMS accurately coordinated control of power generation, energy storage, power consumption conditions, support the use of peak-valley price spread arbitrage to achieve higher returns and meet more personalized needs under the "dual-carbon policy".

This scheme can effectively solve the energy consumption problems of island residents and tourists, ensure a stable power supply on the island, realize the coordinated control of "source-network-load-storage" and economic operation, and provide reliable power supply for the development of island economy, island tourism and other emerging industries. 

Microgrid is the basis and premise of market-oriented transaction of distributed generation. After the completion of parallel microgrid, it can apply for power supply business license like incremental distribution network.
