Technical FAQs 4

What is the current status of Vietnam's power system?

(i)Current status of Vietnam's power system with high RE (solar and wind power) rate, and the capacity of RE projects is greatly fluctuated. (ii) Advantages and disadvantages of operating a power system with a high RE rate. (iii) Demand and necessity of electricity storage in the current and future power system of Vietnam.

Is energy storage system a good investment?

According to international energy experts, when RE electricity rate reachs 15% up, the investment in energy storage system is economically efficient. So, in many countries over the world, the energy storage systems have become the necessary technologies in demand side management, RE and smart grid development.

Should energy storage systems be included in the power development planning VIII?

In the immediate future, it is proposed to add the amount of energy storage systems in the list 2021-2030 of the Power Development Planning VIII to serve as a basis for implementation.

What is the lagest energy storage system in the world?

In the world, at present, beside pump-storage hydropower plant for peak covering, the lagest power storage system reachs only 150 MW and same projects with 500 -600 MW are developing in Australia. III. A number of proposals for energy storage development:
